In this article, we discuss how to create a user registration form with Spring Boot, Spring Security, Hibernate, and Thymeleaf. We validate the user registration fields with hibernate validator annotations and a custom field matching validator to validate if the email and/or password fields match. We will create Role-based Spring security with a MySQL database.
Basically, we will develop a simple User Registration Module using Role-based Spring security which can use in any spring MVC-based project.
We create User and Role tables with many to many relationships between them that is one user can have multiple roles and one role can be assigned to multiple users.
In the previous article, we have learned Spring Boot + Spring MVC + Role Based Spring Security + JPA + Thymeleaf + MySQL Tutorial
Let's get started with our objective of what we'll build?
What we’ll build?
We will develop a simple User Registration Module using Spring Boot 2, Spring MVC, Spring Security, Hibernate 5, Thymeleaf, and MySQL. We validate the user registration fields with hibernate validator annotations and a custom field matching validator to validate if the email and/or password fields match. We will create Role-based Spring security with a MySQL database.
We will develop two main functionalities:
1. Register a user (stored data into MySQL database).
2. Login Authentication - validate user login credentials with database email and password.

Project Structure
Let’s start by looking at the project structure.
The pom.xml File - Maven Dependencies

Spring Security Configuration
We secure our application using Spring Security Form Authentication using the following configuration. Make sure you permit all access to the /registration page and your static resources.
package net.javaguides.springboot.springsecurity.config; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.security.authentication.dao.DaoAuthenticationProvider; import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder; import org.springframework.security.config.annotation.web.builders.HttpSecurity; import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter; import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder; import org.springframework.security.web.util.matcher.AntPathRequestMatcher; import net.javaguides.springboot.springsecurity.service.UserService; @Configuration public class SecurityConfiguration extends WebSecurityConfigurerAdapter { @Autowired private UserService userService; @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .antMatchers( "/registration**", "/js/**", "/css/**", "/img/**", "/webjars/**").permitAll() .anyRequest().authenticated() .and() .formLogin() .loginPage("/login") .permitAll() .and() .logout() .invalidateHttpSession(true) .clearAuthentication(true) .logoutRequestMatcher(new AntPathRequestMatcher("/logout")) .logoutSuccessUrl("/login?logout") .permitAll(); } @Bean public BCryptPasswordEncoder passwordEncoder() { return new BCryptPasswordEncoder(); } @Bean public DaoAuthenticationProvider authenticationProvider() { DaoAuthenticationProvider auth = new DaoAuthenticationProvider(); auth.setUserDetailsService(userService); auth.setPasswordEncoder(passwordEncoder()); return auth; } @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth.authenticationProvider(authenticationProvider()); } }
Configure MySQL and View Resolver
We configure Hibernate using the application.properties file located in the src/main/resources/ folder. Note that we also configure thymeleaf view resolver.
## Spring view resolver set up spring.mvc.view.prefix=/WEB-INF/jsp/ spring.mvc.view.suffix=.jsp ## Spring DATASOURCE (DataSourceAutoConfiguration & DataSourceProperties) spring.datasource.url = jdbc:mysql://localhost:3306/registration_module?useSSL=false spring.datasource.username = root spring.datasource.password = root ## Hibernate Properties # The SQL dialect makes Hibernate generate better SQL for the chosen database spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5InnoDBDialect # Hibernate ddl auto (create, create-drop, validate, update) spring.jpa.hibernate.ddl-auto = update
Database Create SQL Scripts
As we specified spring.jpa.hibernate.ddl-auto = update property will auto create tables in MySQL database. The below are create statements of three tables.
CREATE TABLE `role` ( `id` bigint(20) NOT NULL, `name` varchar(255) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci; CREATE TABLE `user` ( `id` bigint(20) NOT NULL, `email` varchar(255) DEFAULT NULL, `first_name` varchar(255) DEFAULT NULL, `last_name` varchar(255) DEFAULT NULL, `password` varchar(255) DEFAULT NULL, PRIMARY KEY (`id`), UNIQUE KEY `UKob8kqyqqgmefl0aco34akdtpe` (`email`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci; CREATE TABLE `users_roles` ( `user_id` bigint(20) NOT NULL, `role_id` bigint(20) NOT NULL, KEY `FKt4v0rrweyk393bdgt107vdx0x` (`role_id`), KEY `FKgd3iendaoyh04b95ykqise6qh` (`user_id`), CONSTRAINT `FKgd3iendaoyh04b95ykqise6qh` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`), CONSTRAINT `FKt4v0rrweyk393bdgt107vdx0x` FOREIGN KEY (`role_id`) REFERENCES `role` (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;
Spring Rest Controller - UserRegistrationController.java
This controller is mapped to “/registration” URI. We use the UserRegistrationDto to process and validate the user registration form and inject it using the @ModelAttribute("user") annotation. When the form is submitted it’s automatically validated and errors are available in the BindingResult. Next, we check if a user doesn’t already exist with the submitted email. If the form has any errors, we return to the registration page. Otherwise, we redirect and inform the user the registration procedure is complete.
package net.javaguides.springboot.springsecurity.web; import javax.validation.Valid; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.validation.BindingResult; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.ModelAttribute; import org.springframework.web.bind.annotation.PostMapping; import org.springframework.web.bind.annotation.RequestMapping; import net.javaguides.springboot.springsecurity.model.User; import net.javaguides.springboot.springsecurity.service.UserService; import net.javaguides.springboot.springsecurity.web.dto.UserRegistrationDto; @Controller @RequestMapping("/registration") public class UserRegistrationController { @Autowired private UserService userService; @ModelAttribute("user") public UserRegistrationDto userRegistrationDto() { return new UserRegistrationDto(); } @GetMapping public String showRegistrationForm(Model model) { return "registration"; } @PostMapping public String registerUserAccount(@ModelAttribute("user") @Valid UserRegistrationDto userDto, BindingResult result) { User existing = userService.findByEmail(userDto.getEmail()); if (existing != null) { result.rejectValue("email", null, "There is already an account registered with that email"); } if (result.hasErrors()) { return "registration"; } userService.save(userDto); return "redirect:/registration?success"; } }
Spring Rest Controller - MainController.java
This is a simple controller for managing trivial thymeleaf pages.
package net.javaguides.springboot.springsecurity.web; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.GetMapping; @Controller public class MainController { @GetMapping("/") public String root() { return "index"; } @GetMapping("/login") public String login(Model model) { return "login"; } @GetMapping("/user") public String userIndex() { return "user/index"; } }
Data Transfer Object - UserRegistrationDto.java
We use the UserRegistrationDto to validate the user registration form. This DTO is annotated using Hibernate-Validation annotations which validate trivial fields on empty and our own custom @FieldMatch annotations which validates if the password is equal to the confirm password and the email address field is equal to the confirm email address field.
package net.javaguides.springboot.springsecurity.web.dto; import javax.validation.constraints.AssertTrue; import javax.validation.constraints.Email; import javax.validation.constraints.NotEmpty; import net.javaguides.springboot.springsecurity.constraint.FieldMatch; @FieldMatch.List({ @FieldMatch(first = "password", second = "confirmPassword", message = "The password fields must match"), @FieldMatch(first = "email", second = "confirmEmail", message = "The email fields must match") }) public class UserRegistrationDto { @NotEmpty private String firstName; @NotEmpty private String lastName; @NotEmpty private String password; @NotEmpty private String confirmPassword; @Email @NotEmpty private String email; @Email @NotEmpty private String confirmEmail; @AssertTrue private Boolean terms; public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } public String getLastName() { return lastName; } public void setLastName(String lastName) { this.lastName = lastName; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getConfirmPassword() { return confirmPassword; } public void setConfirmPassword(String confirmPassword) { this.confirmPassword = confirmPassword; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public String getConfirmEmail() { return confirmEmail; } public void setConfirmEmail(String confirmEmail) { this.confirmEmail = confirmEmail; } public Boolean getTerms() { return terms; } public void setTerms(Boolean terms) { this.terms = terms; } }
Creating Field Matching Validator
We created a special @FieldMatch annotation to support the validation process of comparing fields with each other if they match. We can input two fields first and second and an optional message.
package net.javaguides.springboot.springsecurity.constraint; import javax.validation.Payload; import javax.validation.Constraint; import java.lang.annotation.Documented; import java.lang.annotation.Retention; import java.lang.annotation.Target; import static java.lang.annotation.ElementType.ANNOTATION_TYPE; import static java.lang.annotation.ElementType.TYPE; import static java.lang.annotation.RetentionPolicy.RUNTIME; @Target({ TYPE, ANNOTATION_TYPE }) @Retention(RUNTIME) @Constraint(validatedBy = FieldMatchValidator.class) @Documented public @interface FieldMatch { String message() default "{constraints.field-match}"; Class < ? > [] groups() default {}; Class < ? extends Payload > [] payload() default {}; String first(); String second(); @Target({ TYPE, ANNOTATION_TYPE }) @Retention(RUNTIME) @Documented @interface List { FieldMatch[] value(); } }
Next, we create a custom validator by implementing the ConstraintValidator. Here we can validate if the given input fields match. If they do we return true if the fields don’t match we return false.
package net.javaguides.springboot.springsecurity.constraint; import javax.validation.ConstraintValidator; import javax.validation.ConstraintValidatorContext; import org.apache.commons.beanutils.BeanUtils; public class FieldMatchValidator implements ConstraintValidator < FieldMatch, Object > { private String firstFieldName; private String secondFieldName; @Override public void initialize(final FieldMatch constraintAnnotation) { firstFieldName = constraintAnnotation.first(); secondFieldName = constraintAnnotation.second(); } @Override public boolean isValid(final Object value, final ConstraintValidatorContext context) { try { final Object firstObj = BeanUtils.getProperty(value, firstFieldName); final Object secondObj = BeanUtils.getProperty(value, secondFieldName); return firstObj == null && secondObj == null || firstObj != null && firstObj.equals(secondObj); } catch (final Exception ignore) {} return true; } }
Service Layer - UserService.java
The UserService extends the UserDetailsService interface.
package net.javaguides.springboot.springsecurity.service; import org.springframework.security.core.userdetails.UserDetailsService; import net.javaguides.springboot.springsecurity.model.User; import net.javaguides.springboot.springsecurity.web.dto.UserRegistrationDto; public interface UserService extends UserDetailsService { User findByEmail(String email); User save(UserRegistrationDto registration); }
Service Layer - UserServiceImpl.java
In the UserServiceImpl we implement the methods to lookup a user by email and to save the user registration using the UserRegistrationDto. Make sure when you save the user you’ll encode his password using the BCryptPasswordEncoder. Otherwise, a database administrator will be able to see his password in clear text.
package net.javaguides.springboot.springsecurity.service; import java.util.Arrays; import java.util.Collection; import java.util.stream.Collectors; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.security.core.GrantedAuthority; import org.springframework.security.core.authority.SimpleGrantedAuthority; import org.springframework.security.core.userdetails.UserDetails; import org.springframework.security.core.userdetails.UsernameNotFoundException; import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder; import org.springframework.stereotype.Service; import net.javaguides.springboot.springsecurity.model.Role; import net.javaguides.springboot.springsecurity.model.User; import net.javaguides.springboot.springsecurity.repository.UserRepository; import net.javaguides.springboot.springsecurity.web.dto.UserRegistrationDto; @Service public class UserServiceImpl implements UserService { @Autowired private UserRepository userRepository; @Autowired private BCryptPasswordEncoder passwordEncoder; public User findByEmail(String email) { return userRepository.findByEmail(email); } public User save(UserRegistrationDto registration) { User user = new User(); user.setFirstName(registration.getFirstName()); user.setLastName(registration.getLastName()); user.setEmail(registration.getEmail()); user.setPassword(passwordEncoder.encode(registration.getPassword())); user.setRoles(Arrays.asList(new Role("ROLE_USER"))); return userRepository.save(user); } @Override public UserDetails loadUserByUsername(String email) throws UsernameNotFoundException { User user = userRepository.findByEmail(email); if (user == null) { throw new UsernameNotFoundException("Invalid username or password."); } return new org.springframework.security.core.userdetails.User(user.getEmail(), user.getPassword(), mapRolesToAuthorities(user.getRoles())); } private Collection < ? extends GrantedAuthority > mapRolesToAuthorities(Collection < Role > roles) { return roles.stream() .map(role - > new SimpleGrantedAuthority(role.getName())) .collect(Collectors.toList()); } }
Spring Data Repository - UserRepository.java
We create the UserRepository by extending the JpaRepository interface. This is a Spring Data interface and gives us all the CRUD operations automatically.
package net.javaguides.springboot.springsecurity.repository; import org.springframework.data.jpa.repository.JpaRepository; import org.springframework.stereotype.Repository; import net.javaguides.springboot.springsecurity.model.User; @Repository public interface UserRepository extends JpaRepository < User, Long > { User findByEmail(String email); }
Create JPA Entities
PA entity - User.java
We have annotated our User and Role objects with Java Persistence API annotations. These annotations are used to map our pojo’s to the database.
package net.javaguides.springboot.springsecurity.model; import javax.persistence.*; import java.util.Collection; @Entity @Table(uniqueConstraints = @UniqueConstraint(columnNames = "email")) public class User { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; private String firstName; private String lastName; private String email; private String password; @ManyToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL) @JoinTable( name = "users_roles", joinColumns = @JoinColumn( name = "user_id", referencedColumnName = "id"), inverseJoinColumns = @JoinColumn( name = "role_id", referencedColumnName = "id")) private Collection < Role > roles; public User() {} public User(String firstName, String lastName, String email, String password) { this.firstName = firstName; this.lastName = lastName; this.email = email; this.password = password; } public User(String firstName, String lastName, String email, String password, Collection < Role > roles) { this.firstName = firstName; this.lastName = lastName; this.email = email; this.password = password; this.roles = roles; } public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } public String getLastName() { return lastName; } public void setLastName(String lastName) { this.lastName = lastName; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public Collection < Role > getRoles() { return roles; } public void setRoles(Collection < Role > roles) { this.roles = roles; } @Override public String toString() { return "User{" + "id=" + id + ", firstName='" + firstName + '\'' + ", lastName='" + lastName + '\'' + ", email='" + email + '\'' + ", password='" + "*********" + '\'' + ", roles=" + roles + '}'; } }
JPA entity - Role.java
package net.javaguides.springboot.springsecurity.model; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; @Entity public class Role { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; private String name; public Role() {} public Role(String name) { this.name = name; } public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } @Override public String toString() { return "Role{" + "id=" + id + ", name='" + name + '\'' + '}'; } }
Spring Boot Application Running
We use spring boot to start our application.
package net.javaguides.springboot.springsecurity; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } }
Thyemeleaf Templates
The thymeleaf pages are built with bootstrap and jquery. All templates are located in the src/main/resources/templates folder. Note that we have used webjars to manage client-side dependencies.
User Registration Page
In the user registration page, we have multiple input fields. For each input field, we have a corresponding error message. On the top of the form, we also have some global error messages.

ReplyDeleteHi there!
ReplyDeleteDownloaded the project via your github link, imported and get the error when running the Application.java file:
"WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.springframework.cglib.core.ReflectUtils$1 (file:/C:/Users/GavinBeere/.m2/repository/org/springframework/spring-core/5.0.8.RELEASE/spring-core-5.0.8.RELEASE.jar) to method java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain)
WARNING: Please consider reporting this to the maintainers of org.springframework.cglib.core.ReflectUtils$1
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release"
Wondering if you have come across this, as I can't find a solution online.
Thanks,
Gav
