How to POST Json to a Play Framework Morphia controller

I first tried using play 1.2.4 with morphia 1.2.6a to post json data to my controller. That always ended with a null pointer exception somewhere inside play, so I switched to play 1.2.3 and i got a bit further, but am still confused. The post call now succeeds but the data never seems to arrive.

route



    POST /mytest    mycontroller.myposttest

mycontroller.java



    public static void myposttest(SampleObject item){
       Gson gs = new GsonBuilder().create();
       System.out.printf(gs.toJson(item));
       //NOTE: item is empty every time
    }

mytest.java



    String jsonText = "{name=\"foo\"}"; 
    Response response = POST("/mytest/","application/json",jsonText);
    //NOTE: the post call succeeds but the jsonText data is not found on the other side

The examples I have read show this as just working, but I have been messing with this for a very long time and have not figured it out. How is this intended to work?

  1. Play cannot bind Json to object direclty
  2. Your post data has no parameter named "item"

You should change your post code to:

Response response = POST("/mytest/","application/json",{item: jsonText});

And your controller code should be:

public static void myposttest(String item){
    Gson gs = new GsonBuilder().create();
    SampleObject obj = gs.fromJson(item);
    obj.save();
    ok();
}
