检索js中嵌套对象的JSON

Question

I have built a web service using java, and the return value is a parsed object to JSON.

the problem is that I have an object that contains a Hashmap<> in it as a parameter, when I parse it to JSON and returns it, How could I handle it in js, how could I get the values of the hashmap.

Here is the object that I parse to JSON.

Object human;

 Hashmap<String, String> properties; properties.put("property1", "value"); properties.put("property2", "value"); properties.put("property3", "value"); /* here where I got the object that contains several attributes beside the hashmap that is considered as object*/ human.setProperties(properties); 

return aGson.toJson(human);

Answer 1

Once you've received your JSON text from the web service, parse it in JavaScript as

var human = JSON.parse( jsonTextFromWS );
console.log( human.properties.property1 ); // value

Answer 2

Use the org.json.JSONObject class, like this:

JSONObject jsonHuman = new JSONObject( human );

It should use reflection to find all the public fields and build a valid JSON object for you.
