测试
1先查看陈经理的当前任务

    /**查询当前人的个人任务*/
    @Test
    public void findMyPersonalTask(){
        String assignee = "陈经理";
        List<Task> list = processEngine.getTaskService()//与正在执行的任务管理相关的Service
                        .createTaskQuery()//创建任务查询对象
                        /**查询条件（where部分）*/
                        .taskAssignee(assignee)//指定个人任务查询，指定办理人
//                      .taskCandidateUser(candidateUser)//组任务的办理人查询
//                      .processDefinitionId(processDefinitionId)//使用流程定义ID查询
//                      .processInstanceId(processInstanceId)//使用流程实例ID查询
//                      .executionId(executionId)//使用执行对象ID查询
                        /**排序*/
                        .orderByTaskCreateTime().asc()//使用创建时间的升序排列
                        /**返回结果集*/
//                      .singleResult()//返回惟一结果集
//                      .count()//返回结果集的数量
//                      .listPage(firstResult, maxResults);//分页查询
                        .list();//返回列表
        if(list!=null && list.size()>0){
             System.out.println("--关联表：  ACT_RU_TASK----");
                for(Task task:list){
                       System.out.println("--------"+task.getAssignee()+"任务:"+task.getName()+"-----------------");
                        System.out.println("任务ID:"+task.getId());
                        System.out.println("任务名称:"+task.getName());
                        System.out.println("任务的创建时间:"+task.getCreateTime());
                        System.out.println("任务的办理人:"+task.getAssignee());
                        System.out.println("流程实例ID："+task.getProcessInstanceId());
                        System.out.println("执行对象ID:"+task.getExecutionId());
                        System.out.println("流程定义ID:"+task.getProcessDefinitionId());
//                      任务ID:2704
//                      任务名称:部门经理审批
//                      任务的创建时间:Wed Sep 06 20:23:31 CST 2017
//                      任务的办理人:陈经理
//                      流程实例ID：2701
//                      执行对象ID:2701
//                      流程定义ID:sequenceFlow:4:2604
                }
        }
    }

2通过流程变量来控制流程连线

    /**完成我的任务*/
    @Test
    public void completeMyPersonalTask(){
        //任务ID
        String taskId = "2704";
        //完成任务的同时，设置流程变量，使用流程变量用来指定完成任务后，下一个连线，对应sequenceFlow.bpmn文件中${message=='不重要'}
        Map<String, Object> variables = new HashMap<String, Object>();
        variables.put("message", "一级费用");//通过流程变量来控制流程的路线
        processEngine.getTaskService()//与正在执行的任务管理相关的Service
                    .complete(taskId,variables);
        System.out.println("完成任务：任务ID："+taskId);
//      完成任务：任务ID：2704
    }

查看数据库当前运行的任务表

可以看到任务已经走到总经理审批了。

同理当完成任务那里设置流程变量为二级费用，那么任务就走向结束
