Java - Spring Security Configuration filter any requests except a specific endpoint?

In Spring Security, you can configure a security filter to allow access to a specific endpoint while securing all other requests. Here's an example using Java configuration:

import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.security.config.annotation.web.builders.HttpSecurity; import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity; import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter; import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter; @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .antMatchers("/your-specific-endpoint").permitAll() // Allow access to a specific endpoint .anyRequest().authenticated() // Secure all other requests .and() .addFilterBefore(yourCustomFilter(), UsernamePasswordAuthenticationFilter.class); } @Bean public YourCustomFilter yourCustomFilter() { return new YourCustomFilter(); } }

In this example:

  1. antMatchers("/your-specific-endpoint").permitAll() allows unrestricted access to the specified endpoint (/your-specific-endpoint in this case).
  2. anyRequest().authenticated() ensures that all other requests are subject to authentication.

Make sure to replace "/your-specific-endpoint" with the actual endpoint path you want to allow unrestricted access to.

Additionally, you can define a custom filter (YourCustomFilter) and add it using addFilterBefore(yourCustomFilter(), UsernamePasswordAuthenticationFilter.class). This allows you to customize the security behavior for specific requests or endpoints.

import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter; public class YourCustomFilter extends UsernamePasswordAuthenticationFilter { // Your custom filter logic goes here }

This is a basic example, and you may need to customize it further based on your specific requirements and the authentication mechanisms you are using in your application.

Examples

  1. "Spring Security allow access to specific endpoint only"

    • Code:
      @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .antMatchers("/specificEndpoint").permitAll() .anyRequest().authenticated() .and() .formLogin() .and() .httpBasic(); } }
    • Description: Use antMatchers to allow access to "/specificEndpoint" and authenticate any other requests.

  2. "Spring Security allow access to multiple specific endpoints"

    • Code:
      @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .antMatchers("/specificEndpoint1", "/specificEndpoint2").permitAll() .anyRequest().authenticated() .and() .formLogin() .and() .httpBasic(); } }
    • Description: Extend antMatchers to allow access to multiple specific endpoints.

  3. "Spring Security filter all requests except one endpoint for authenticated users"

    • Code:
      @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .antMatchers("/specificEndpoint").authenticated() .anyRequest().denyAll() .and() .formLogin() .and() .httpBasic(); } }
    • Description: Authenticate users for "/specificEndpoint" and deny access to all other requests.

  4. "Spring Security allow access to specific endpoint based on role"

    • Code:
      @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .antMatchers("/specificEndpoint").hasRole("ROLE_USER") .anyRequest().authenticated() .and() .formLogin() .and() .httpBasic(); } }
    • Description: Allow access to "/specificEndpoint" only for users with the role "ROLE_USER."

  5. "Spring Security filter all requests except one endpoint for specific user"

    • Code:
      @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .antMatchers("/specificEndpoint").hasUsername("specificUser") .anyRequest().denyAll() .and() .formLogin() .and() .httpBasic(); } }
    • Description: Allow access to "/specificEndpoint" only for a specific user and deny access to all other requests.

  6. "Spring Security filter requests based on IP address"

    • Code:
      @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .antMatchers("/specificEndpoint").hasIpAddress("192.168.1.1") .anyRequest().denyAll() .and() .formLogin() .and() .httpBasic(); } }
    • Description: Allow access to "/specificEndpoint" only for requests from the specified IP address.

  7. "Spring Security allow access to specific endpoint without authentication"

    • Code:
      @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .antMatchers("/specificEndpoint").permitAll() .anyRequest().authenticated() .and() .formLogin() .and() .httpBasic(); } }
    • Description: Allow access to "/specificEndpoint" without authentication and authenticate all other requests.

  8. "Spring Security allow access to specific endpoint for anonymous users"

    • Code:
      @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .antMatchers("/specificEndpoint").anonymous() .anyRequest().authenticated() .and() .formLogin() .and() .httpBasic(); } }
    • Description: Allow access to "/specificEndpoint" for anonymous users and authenticate all other requests.

  9. "Spring Security allow access to specific endpoint for specific authentication method"

    • Code:
      @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .antMatchers("/specificEndpoint").permitAll() .anyRequest().authenticated() .and() .formLogin() .and() .httpBasic() .and() .oauth2Login(); } }
    • Description: Allow access to "/specificEndpoint" for all authentication methods and authenticate all other requests.

  10. "Spring Security allow access to specific endpoint with custom access decision"

    • Code:
      @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .antMatchers("/specificEndpoint").access("@customAccessDecisionService.check(authentication)") .anyRequest().authenticated() .and() .formLogin() .and() .httpBasic(); } @Bean public CustomAccessDecisionService customAccessDecisionService() { return new CustomAccessDecisionService(); } }
    • Description: Use a custom access decision service to control access to "/specificEndpoint" based on custom logic.
