jfinal 前台ajax发送json数据（java对象），controller接收json数据，并转化对象

	    var obj = new Object();
	    obj.taskType = task_type;
	    obj.taskName = task_name;
	    obj.createTime = create_time;
	    obj.executionInterval = execution_interval;
	    obj.taskDec = task_dec;
	    console.log(obj);
	    $.ajax({
	        url : 'mod3/addTaskInfo',
	        data : JSON.stringify(obj),
	        type : 'POST',
	        dataType : 'json',
	        success : function(data) {
		        if (data) {
		        	
		        } else {
		        	
		        }
	        }
	    });

	public void addTaskInfo() {
		String jsonString = HttpKit.readData(getRequest());
		TaskInfoVo taskInfoVo = FastJson.getJson().parse(jsonString, TaskInfoVo.class);
    }
