Activiti任务权限查询

一代码

package com.syc.activiti;


import java.util.ArrayList;
import java.util.List;


import org.activiti.engine.IdentityService;
import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.TaskService;
import org.activiti.engine.identity.Group;
import org.activiti.engine.identity.User;
import org.activiti.engine.task.IdentityLink;
import org.activiti.engine.task.Task;


public class Query {


    public static void main( String[] args ) {
        //获取流程引擎实例
        ProcessEngine engine = ProcessEngines.getDefaultProcessEngine();
        // 获取身份服务组件
        IdentityService identityService = engine.getIdentityService();
        // 新建用户
        User user = creatUser(identityService, "user1", "张三", "last", "abc@163.com", "123");
        // 新建用户组
        Group groupA = createGroup(identityService, "group1", "经理组", "manager");
        Group groupB = createGroup(identityService, "group2", "员工组", "employee");
        // 获取任务服务组件
        TaskService taskService = engine.getTaskService();
        //保存第一个Task
        Task task1 = taskService.newTask("task1");
        task1.setName("申请假期");
        taskService.saveTask(task1);
        //保存第二个Task
        Task task2 = taskService.newTask("task2");
        task2.setName("审批假期");
        taskService.saveTask(task2);
        //绑定权限
        taskService.addCandidateGroup("task1", groupA.getId());
        taskService.addCandidateGroup("task2", groupB.getId());
        taskService.addCandidateUser("task2", user.getId());
        //根据用户组查询任务
        List<Task> tasks = taskService.createTaskQuery().taskCandidateGroup(groupA.getId()).list();
        System.out.println("经理组的候选任务有：");
        for (Task task : tasks) {
            System.out.println("   " + task.getName());
        }
        //根据用户查询任务
        tasks = taskService.createTaskQuery().taskCandidateUser(user.getId()).list();
        System.out.println("张三的候选任务有");
        for (Task task : tasks) {
            System.out.println("   " + task.getName());
        }
        //调用taskCandidateGroupIn
        List<String> groupIds = new ArrayList<String>();
        groupIds.add(groupA.getId());
        groupIds.add(groupB.getId());
        tasks = taskService.createTaskQuery().taskCandidateGroupIn(groupIds).list();
        System.out.println("经理组与员工组的任务有：");
        for (Task task : tasks) {
            System.out.println("   " + task.getName());
        }
        //查询权限数据
        List<IdentityLink> links = taskService.getIdentityLinksForTask(tasks.get(1).getId());
        System.out.println("关系数据量: " + links.size());
    }


    // 将用户组数据保存到数据库中
    static Group createGroup( IdentityService identityService, String id,
                              String name, String type ) {
        // 调用newGroup方法创建Group实例
        Group group = identityService.newGroup(id);
        group.setName(name);
        group.setType(type);
        identityService.saveGroup(group);
        return identityService.createGroupQuery().groupId(id).singleResult();
    }


    //创建用户方法
    static User creatUser( IdentityService identityService, String id, String first,
                           String last, String email, String passwd ) {
        // 使用newUser方法创建User实例
        User user = identityService.newUser(id);
        // 设置用户的各个属性
        user.setFirstName(first);
        user.setLastName(last);
        user.setEmail(email);
        user.setPassword(passwd);
        // 使用saveUser方法保存用户
        identityService.saveUser(user);
        return identityService.createUserQuery().userId(id).singleResult();
    }
}

二运行结果

经理组的候选任务有：
   申请假期
张三的候选任务有
   审批假期
经理组与员工组的任务有：
   申请假期
   审批假期
关系数据量: 2
