Activiti6自学之路（六）——Activiti中用户与用户组

桃扇骨 2022-01-16 07:49 1603阅读 1赞

Activiti中内置了一套用户、用户组关系，以及对它们的操作API。关于用户和用户组表工业四张，如下图

## 一、用户与用户组表的介绍 ##

**1、ACT\_ID\_USER（用户信息表）**

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI5OTE0ODM3_size_16_color_FFFFFF_t_70]

**2、ACT\_ID\_INFO（用户扩展信息表）**

**3、ACT\_ID\_GROUP（用户组信息表）**

**4、ACT\_ID\_MEMBERSHIP（用户与用户组关系信息表）**

## 二、项目中用户和角色与Activiti中的用户、用户组整合 ##

通常来说在项目中都已经是有了用户和角色权限功能。比如我创建了一个springboot项目，已经创建了用户表和角色表，那么如何将项目本身的用户和角色与activiti的用户、用户组整合在一起啦。

我的思路：在项目中创建了用户时，同时也需要将用户与Activiti的用户关联起来，直接通过id关联即可。

## 三、创建Activiti用户 ##

package com.springboot.activiti.eimm.leave.controller;
    
    import java.io.FileInputStream;
    import java.io.FileNotFoundException;
    import java.io.InputStream;
    import java.util.zip.ZipInputStream;
    
    import org.activiti.engine.HistoryService;
    import org.activiti.engine.IdentityService;
    import org.activiti.engine.ProcessEngine;
    import org.activiti.engine.RepositoryService;
    import org.activiti.engine.RuntimeService;
    import org.activiti.engine.TaskService;
    import org.activiti.engine.identity.Group;
    import org.activiti.engine.identity.User;
    import org.activiti.engine.repository.Deployment;
    import org.junit.Test;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    import com.springboot.activiti.eimm.leave.dao.LeaveMapper;
    import com.springboot.activiti.eimm.leave.service.LeaveService;
    
    import lombok.extern.slf4j.Slf4j;
    
    @Controller
    @Slf4j
    @RequestMapping("/leave")
    public class LeaveController {
    
    	@Autowired
    	LeaveMapper leaveMapper;
    	
    	@Autowired
    	private RuntimeService runtimeService;
    
    	@Autowired
    	private TaskService taskService;
    
    	@Autowired
    	private IdentityService identityService;
    
    	@Autowired
    	private RepositoryService repositoryService;
    
    	@Autowired
    	private ProcessEngine processEngine;
    
    	@Autowired
    	private HistoryService historyService;
    	
    	@Autowired
    	private LeaveService leaveService;
    	
    	//1、部署流程资源【第一种方式：classpath】
    	@RequestMapping("/deploy1")
    	public void deploy1( ){	
    		Deployment deployment = processEngine.getRepositoryService()//获取流程定义和部署对象相关的Service
    				.createDeployment()//创建部署对象
    				.name("请假申请审核流程")//声明流程的名称
    				.addClasspathResource("processes/leave.bpmn")//加载资源文件，一次只能加载一个文件
    				.addClasspathResource("processes/leave.png")//
    				.deploy();//完成部署
    		System.out.println("部署ID："+deployment.getId());//1
    		System.out.println("部署时间："+deployment.getDeploymentTime());
     
    	}
    	
     
    	
    	//2、创建Activiti用户
      	@RequestMapping("/addUser")
      	public void addUser( ){	
      		//项目中每创建一个新用户，对应的要创建一个Activiti用户,两者的userId和userName一致
      		  
      		//添加用户
      		User user1 = identityService.newUser("user1");
      		user1.setFirstName("张三");
      		user1.setLastName("张");
      		user1.setPassword("123456");
      		user1.setEmail("zhangsan@qq.com");
      	    identityService.saveUser(user1);
      	      
      	    User user2 = identityService.newUser("user2");
      	    user2.setFirstName("李四");
      	  	user2.setLastName("李");
      	  	user2.setPassword("123456");
      	  	user2.setEmail("lisi@qq.com");
      	    identityService.saveUser(user2);
      		  
      	    User user3 = identityService.newUser("user3");
      	    user3.setFirstName("王五");
      	    user3.setLastName("王");
      		user3.setPassword("123456");
      		user3.setEmail("wangwu@qq.com");
      		 identityService.saveUser(user3);
    	  	
    	  	 User user4 = identityService.newUser("user4");
    	  	 user4.setFirstName("吴六");
    	  	 user4.setLastName("吴");
    	  	 user4.setPassword("123456");
    	  	 user4.setEmail("wuliu@qq.com");
    	  	 identityService.saveUser(user4);
      	      
      	}
    	
    	
    }

启动程序：[http://127.0.0.1:8080/项目名称/leave/addUser][http_127.0.0.1_8080_leave_addUser]

发现 act\_id\_user表 新增了四条用户信息

## 四、查询Activiti用户 ##

Activiti提供很多方法来查询用户，我们这里采用根据用户id来查询

//3、根据id查询Activiti用户
      	@RequestMapping("/queryUser")
      	public void queryUser( ){	
      		 
      		User user = identityService.createUserQuery().userId("user1").singleResult(); 
      		System.out.println(user.getId());
      		System.out.println(user.getFirstName());
      		System.out.println(user.getLastName());
      		System.out.println(user.getPassword());
      		System.out.println(user.getEmail());
      	      
      	}

![在这里插入图片描述][20190615160521330.png]

## 四、创建Activiti用户组 ##

Activiti中的用户组信息相当于权限系统当中的角色，用户可以属于多个用户组，用户组也可以包含多个用户，同一个用户组当中的用户具有相同的权限。

//4、创建Activiti用户组
      	@RequestMapping("/addGroup")
      	public void addGroup( ){	
      		 
      		Group group1 = identityService.newGroup("group1");
            group1.setName("员工组");
           group1.setType("员工组");
            identityService.saveGroup(group1);
            
            Group group2 = identityService.newGroup("group2");
            group2.setName("总监组");
            group2.setType("总监阻");
            identityService.saveGroup(group2);
            
            Group group3 = identityService.newGroup("group3");
            group3.setName("经理组");
            group3.setType("经理组");
            identityService.saveGroup(group3);
            
            Group group4 = identityService.newGroup("group4");
            group4.setName("人力资源组");
            group4.setType("人力资源组");
            identityService.saveGroup(group4);
      	      
      	}

![在这里插入图片描述][20190615162248436.png]

## 五、查询Activiti用户组 ##

//5、通过用户组id查询Activiti用户组
      	@RequestMapping("/queryGroup")
      	public void queryGroup( ){	
      		 
      		Group group = identityService.createGroupQuery().groupId("group1").singleResult();
      		System.out.println(group.getId());
      		System.out.println(group.getName());
      		System.out.println(group.getType());
      		 
      	}

![在这里插入图片描述][20190615162427264.png]

## 六、创建Activiti（用户-用户组）关系 ##

//6、创建Activiti（用户-用户组）关系
      	@RequestMapping("/addMembership")
      	public void addMembership( ){	
      		 
      		identityService.createMembership("user1", "group1");//user1 在员工阻
      		identityService.createMembership("user2", "group2");//user2在总监组
      		identityService.createMembership("user3", "group3");//user3在经理组
      		identityService.createMembership("user4", "group4");//user4在人力资源组
      		 
      	}

![在这里插入图片描述][20190615162500510.png]

## 七、查询属于用户组group1的用户 ##

//7、查询属于组group1的用户
      	@RequestMapping("/queryUserListByGroup")
      	public void queryUserListByGroup( ){	
      		 
      	    //查询属于组group1的用户
      		List<User> usersInGroup = identityService.createUserQuery().memberOfGroup("group1").list();
      		for (User user : usersInGroup) {
    			System.out.println(user.getFirstName());
    		}
      		 
      	}

![在这里插入图片描述][20190615162635955.png]

## 八、查询用户user1所属于的用户组 ##

//8、查询user1所属于的组
      	@RequestMapping("/queryGroupListByUser")
      	public void queryGroupListByUser( ){	
      		 
      	    //查询user1所属于的组
      		List<Group> groupsForUser = identityService.createGroupQuery().groupMember("user1").list();
      		for (Group group : groupsForUser) {
    			System.out.println(group.getName());
    		}
      		 
      	}
