SpringBoot怎么整合Activiti7

本篇内容主要讲解“SpringBoot怎么整合Activiti7”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“SpringBoot怎么整合Activiti7”吧!

1.使用idea创建springboot项目

在工程的pom.xml文件中引入相关的依赖，具体依赖如下所示

<?xml version="1.0" encoding="utf-8"?> <project xmlns="http://maven.apache.org/pom/4.0.0" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"      xsi:schemalocation="http://maven.apache.org/pom/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">   <modelversion>4.0.0</modelversion>   <parent>     <groupid>org.springframework.boot</groupid>     <artifactid>spring-boot-starter-parent</artifactid>     <version>2.2.1.release</version>     <relativepath/> <!-- lookup parent from repository -->   </parent>   <groupid>com.example</groupid>   <artifactid>activiti</artifactid>   <version>0.0.1-snapshot</version>   <name>activiti</name>   <description>demo project for spring boot</description>   <properties>     <project.build.sourceencoding>utf-8</project.build.sourceencoding>     <project.reporting.outputencoding>utf-8</project.reporting.outputencoding>     <java.version>1.8</java.version>   </properties>   <dependencies>     <dependency>       <groupid>org.springframework.boot</groupid>       <artifactid>spring-boot-starter-jdbc</artifactid>     </dependency>     <dependency>       <groupid>org.springframework.boot</groupid>       <artifactid>spring-boot-starter-web</artifactid>     </dependency>     <dependency>       <groupid>org.springframework.boot</groupid>       <artifactid>spring-boot-starter-test</artifactid>       <scope>test</scope>     </dependency>     <dependency>       <groupid>org.activiti</groupid>       <artifactid>activiti-spring-boot-starter</artifactid>       <version>7.0.0.beta2</version>     </dependency>     <dependency>       <groupid>org.mybatis</groupid>       <artifactid>mybatis</artifactid>       <version>3.4.5</version>     </dependency>     <dependency>       <groupid>mysql</groupid>       <artifactid>mysql-connector-java</artifactid>       <version>5.1.27</version>     </dependency>     <dependency>       <groupid>org.projectlombok</groupid>       <artifactid>lombok</artifactid>       <optional>true</optional>     </dependency>   </dependencies>   <build>     <plugins>       <plugin>         <groupid>org.springframework.boot</groupid>         <artifactid>spring-boot-maven-plugin</artifactid>       </plugin>     </plugins>   </build> </project>

2.application.yml文件配置

为了能够实现activiti7生成的表放到mysql数据库中，需要在配置文件application.yml中添加相关的配置

server:  port: 8085 spring:  application:   name: spring-activiti  datasource:   url: jdbc:mysql://localhost:3306/activiti?useunicode=true&characterencoding=utf8&servertimezone=gmt&nullcatalogmeanscurrent=true   username: root   password: 123456   driver-class-name: com.mysql.jdbc.driver  activiti:   #1.flase： 默认值。activiti在启动时，会对比数据库表中保存的版本，如果没有表或者版本不匹配，将抛出异常   #2.true： activiti会对数据库中所有表进行更新操作。如果表不存在，则自动创建   #3.create_drop： 在activiti启动时创建表，在关闭时删除表（必须手动关闭引擎，才能删除表）   #4.drop-create： 在activiti启动时删除原来的旧表，然后在创建新表（不需要手动关闭引擎）   database-schema-update: true   #检测历史表是否存在   db-history-used: true   #记录历史等级 可配置的历史级别有none, activity, audit, full   history-level: full   #校验流程文件，默认校验resources下的processes文件夹里的流程文件   check-process-definitions: false

3.添加springsecurity安全框架整合配置

activiti7与springboot整合后，默认情况下，集成了springsecurity安全框架，这样我们就要去准备springsecurity整合进来的相关用户权限配置信息

1）添加securityutil类

为了能够快速实现springsecurity安全框架的配置，所添加的一个组件。

@component public class securityutil {   private logger logger = loggerfactory.getlogger(securityutil.class);   @autowired   @qualifier("myuserdetailsservice")   private userdetailsservice userdetailsservice;   public void loginas(string username) {     userdetails user = userdetailsservice.loaduserbyusername(username);     if (user == null) {       throw new illegalstateexception("user " + username + " doesn't exist, please provide a valid user");     }     logger.info("> logged in as: " + username);     securitycontextholder.setcontext(new securitycontextimpl(new authentication() {       @override       public collection<? extends grantedauthority> getauthorities() {         return user.getauthorities();       }       @override       public object getcredentials() {         return user.getpassword();       }       @override       public object getdetails() {         return user;       }       @override       public object getprincipal() {         return user;       }       @override       public boolean isauthenticated() {         return true;       }       @override       public void setauthenticated(boolean isauthenticated) throws illegalargumentexception {       }       @override       public string getname() {         return user.getusername();       }     }));     org.activiti.engine.impl.identity.authentication.setauthenticateduserid(username);   } }

这个类可以从activiti7官方提供的example中找到。

2）添加demoapplicationconfig类

它的作用是为了实现springsecurity框架的用户权限的配置，这样我们就可以在系统中使用用户权限信息

@configuration public class demoapplicationconfiguration {   private logger logger = loggerfactory.getlogger(demoapplicationconfiguration.class);   @bean   public userdetailsservice myuserdetailsservice() {     inmemoryuserdetailsmanager inmemoryuserdetailsmanager = new inmemoryuserdetailsmanager();     string[][] usersgroupsandroles = {         {"salaboy", "password", "role_activiti_user", "group_activititeam"},         {"ryandawsonuk", "password", "role_activiti_user", "group_activititeam"},         {"erdemedeiros", "password", "role_activiti_user", "group_activititeam"},         {"other", "password", "role_activiti_user", "group_otherteam"},         {"system", "password", "role_activiti_user"},         {"admin", "password", "role_activiti_admin"},     };     for (string[] user : usersgroupsandroles) {       list<string> authoritiesstrings = arrays.aslist(arrays.copyofrange(user, 2, user.length));       logger.info("> registering new user: " + user[0] + " with the following authorities[" + authoritiesstrings + "]");       inmemoryuserdetailsmanager.createuser(new user(user[0], passwordencoder().encode(user[1]),           authoritiesstrings.stream().map(s -> new simplegrantedauthority(s)).collect(collectors.tolist())));     }     return inmemoryuserdetailsmanager;   }   @bean   public passwordencoder passwordencoder() {     return new bcryptpasswordencoder();   } }

4）创建测试类

@springboottest @slf4j class activitiapplicationtests {   @autowired   private processengine processengine;   /**    * 流程定义的部署    */   @test   public void createdeploy() {      repositoryservice repositoryservice = processengine.getrepositoryservice();     deployment deployment = repositoryservice.createdeployment()         .addclasspathresource("diagram/holiday.bpmn")//添加bpmn资源         .addclasspathresource("diagram/holiday.png")         .name("请假申请单流程")         .deploy();               log.info("流程部署id:" + deployment.getname());     log.info("流程部署名称:" + deployment.getid());   } }

运行结果：

遇到的问题：

1）历史表默认不会生成，需在application.yml中配置

spring:  activiti:   #检测历史表是否存在   db-history-used: true   #记录历史等级 可配置的历史级别有none, activity, audit, full   history-level: full
