Json with java hashmap

问题

I have hashmap object,

Map testData=new HashMap();
testData.put("test","test1");

I am able to convert this map using json file with Gson library. I know how to get that data using jQuery getJSON.

My question is: how to display both key and value pairs?

回答1:

What about using gson on the server side, and use jQuery's .getJSON on the client-side?

EDIT: added a for-each example according to your changed question, try it here: http://jsfiddle.net/5gEYf/

var response =  {"test": "test1"};
$.each(response, function(key, value) { 
    alert(key + ' -> ' + value); 
});

EDIT:

I stumbled upon this two year old answer of mine, and like to add that I would use Jackson for JSON de- / serialization in Java nowadays.
