使用com.alibaba.fastjson.JSONObject构造一个简单的JSON数据，构造的数据类似于：
{
"data": {
"jfhf": "fff",
"otherData": [
{
"f445": "fff",
"f44": "fff",
"f12": "fff" }
],
"userData": {
"ff": "fff",
"f1f": "fff",
"f2f": "fff" },
"jf43hf": "ggg",
"jfh4f": "ggg"
},
"userName": "lin",
"password": "lin123"
}

list.add(param4);
}
param2.put("otherData", list);
JSONObject jsonObject1 = new JSONObject();
jsonObject1.put("data", param2);
JSONObject jsonThree = new JSONObject();
jsonThree.putAll(param1);
jsonThree.putAll(jsonObject1);
System.out.println(jsonThree.toString());

第一层就简单的包含{“userName”:”lin”,”password”:”lin123”}，第二层就为data层，即为代码中的param2集合，param2这个集合放置另一列表和另一集合，并且构造出需要的json数据，大家看代码理解吧，应该挺容易的！
