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

  4.0.0      org.springframework.boot    spring-boot-starter-parent    2.2.1.release         com.example  activiti  0.0.1-snapshot  activiti  demo project for spring boot      utf-8    utf-8    1.8              org.springframework.boot      spring-boot-starter-jdbc              org.springframework.boot      spring-boot-starter-web              org.springframework.boot      spring-boot-starter-test      test              org.activiti      activiti-spring-boot-starter      7.0.0.beta2              org.mybatis      mybatis      3.4.5              mysql      mysql-connector-java      5.1.27              org.projectlombok      lombok      true                          org.springframework.boot        spring-boot-maven-plugin            

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: 8085spring: 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。

@componentpublic 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 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

@configurationpublic 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 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@slf4jclass 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
