将String转换为JSON对象数组并解析它们

Question

I have a string in the format like this

[{name:"abc",test:"123",jack:{tret:"abc",cold:"yes"},killer:"yes"},{name:"pqr",test:"456",jack:{tret:"hg",cold:"No"},killer:"No"}]

I know that this is an array of JSON objects.How do I convert this so?

As of now i am just using split and removing all the commas and other things from the string and storing in an array.Is there any better way to do so?

Answer 1

Use the https://code.google.com/p/json-simple/ library for handling JSON.

Here is a sample code:

JSONObject json = (JSONObject)new JSONParser().parse("{\"name\":\"MyNode\", \"width\":200, \"height\":100}");
System.out.println("name=" + json.get("name"));
System.out.println("width=" + json.get("width"));

Please refer to this stackoverflow answer for more answers in this matter.

Answer 2

Using a JSON library is definitely the way to go, but I might suggest one that's being actively developed such as jackson or gson . Both have extensive documentation and examples.

Answer 3

我使用谷歌的Gson库

JsonElement parse = (new JsonParser()).parse(jsonString);

你可以使用杰克逊库，你可以通过它来解析http://www.mkyong.com/java/jackson-tree-model-example/
