兔哥，你ajax是type: "get"，但是activiti-rest源码 https://gist.github.com/4452848 里面

  String assignee = null;
  if(taskJSON.path("assignee") != null && taskJSON.path("assignee").getTextValue() != null) {
    assignee = taskJSON.path("assignee").getTextValue();
    task.setAssignee(assignee);
  }

这个方法是在
@post
public TaskResponse updateTask(Representation entity) {}里面
，我不太懂，
get调用的时候按我的理解应该调用的是

@get
public TaskResponse getTask() {}方法呀？

【注】：router.attach("/tasks", TasksResource.class);

请兔哥指教下，这个restlet在route绑定类后（这个类有get、put、post、delete方法）是如何在ajax中去区分调用的

ajax调用的时候有type来对于get、put、post、delete，问题是restlet里面java的方法如何对应的去调用？
