比如说现在申请人需要往下一个审批人传一些值告诉他我是谁谁谁，然后审批人获取该值，那么可以这么做，具体操作如下：

1）使用processEngine.getTaskService().setVariable(String taskId, String variableName, Object value)来设置传递值：

在上一篇原有上加processEngine.getTaskService().setVariable("57505","name","我是menco");//第一个为任务id,第二个为所谓的自定义标示key,第三个为value

   @Test   publicvoid completeTask(){        Map<String,Object> map= newHashMap<String,Object>();        map.put("user", "cwh");        map.put("day",3);        String taskId = "57505";        processEngine.getTaskService().setVariable(taskId, "name", "我是menco");        processEngine.getTaskService().complete(taskId,map);//完成任务        System.out.println("完成任务，任务ID"+taskId);}

这样提交之后经理审批就可以同variableName来拿到对应的value了

2）使用processEngine.getTaskService().getVariable(String taskId, StringvariableName)来获取值

         @Test          publicvoid getVariable(){           TaskService taskService = processEngine.getTaskService();           String taskid = "55003";           String name =(String) taskService.getVariable(taskid, "name");//“name”对应前面set的variableName           System.out.println(name);  }

运行后得到：

Ok这样就可以了，但是平时我们需要的是一个对象来传递，比如申请人在页面填写申请表单，然后提交上去，这样的话我们后台传的是一个表单对象，那么对应对象怎么传值取值，其实和上面差不多，不过要注意一点就是传的对象类需要实现系列化Serializable，具体操作如下：

1）创建一个taskform.java:

  package com.cwh.activiti; import java.io.Serializable; publicclass Taskform implements Serializable{  privatestaticfinallongserialVersionUID= 8571222190258948731L;  privateintday;  private String type;  private String reason;   public Taskform(int day, String type, String reason) {      super();      this.day = day;      this.type = type;      this.reason = reason;  }  publicint getDay() {      returnday;  }  publicvoid setDay(intday) {      this.day = day;  }  public String getType() {      returntype;  }  publicvoid setType(String type) {      this.type = type;  }  public String getReason() {      returnreason;  }  publicvoid setReason(String reason) {      this.reason = reason;  }  @Override  public String toString() {      return"Taskform[day=" + day + ", type="+ type+ ", reason=" + reason              + "]";  } }

2）操作提交申请

 @Test    publicvoid completeTask(){        Map<String,Object> map= newHashMap<String,Object>();        Taskform taskform = new Taskform(3, "事假", "今天老子不想上班");        map.put("user", "cwh");        map.put("day", taskform.getDay());        String taskId = "57505";        processEngine.getTaskService().setVariable(taskId,"taskform", taskform);        processEngine.getTaskService().complete(taskId,map);//完成任务        System.out.println("完成任务，任务ID"+taskId);   }

3）获取对象值：

  /**     * 获取流程变量     */    @Test    publicvoid getVariable(){        TaskService taskService = processEngine.getTaskService();        String taskid = "65006";        Taskform taskform =(Taskform) taskService.getVariable(taskid, "taskform");        System.out.println(taskform.toString());   }

运行后：
