#### 调用第三方接口时经常要按照约束文档构建各种格式的JSON对象 ####

构建一个格式稍微复杂点的JSON对象
    对象里边包含普通键值对、数组、对象等
    {
        "total": "1",
        "hits": [
            {
                "id": ".watcher-history-3-2017.09.7",
                "index": "logstash",
                "jsaInnerJso": {
                    "message": "测试数据查看返回值",
                    "hostIP": "22.5.254.175"
                }
            }
        ]
    }

public class CreatJSONObject { 
    
        /** * * { "total": "1", "hits": [ { "id": ".watcher-history-3-2017.09.7", "index": "logstash", "jsaInnerJso": { "message": "测试数据查看返回值", "hostIP": "22.5.254.175" } } ] } */
        public static JSONObject createJSONObject(){
            //最外层的JSON对象
            JSONObject jso = new JSONObject();
            jso.put("total", "1");
            //hits的值是一个数组
            JSONArray jsa = new JSONArray();
            //数组里边装着个对象
            JSONObject jsaInnerJso = new JSONObject();
            jsaInnerJso.put("id", ".watcher-history-3-2017.09.7");
            jsaInnerJso.put("index", "logstash");
    
            //数组里边对象的source元素的值也是一个对象
            JSONObject jsaInner_inner_JsoValue = new JSONObject();
            jsaInner_inner_JsoValue.put("hostIP","22.5.254.175");
            jsaInner_inner_JsoValue.put("message", "测试数据查看返回值");
    
            //不数组里边对象的source元素添加进去
            jsaInnerJso.put("jsaInnerJso", jsaInner_inner_JsoValue);
    
            //将数组里边的对象添加进数组
            jsa.add(jsaInnerJso);
    
            //最外层的JSON对象添加hits元素
            jso.put("hits", jsa);
            //搞定
            return jso;
        }
        //测试一下
        public static void main(String[] args) {
            System.out.println(createJSONObject());
        }

结果：

{"total":"1","hits":[{"id":".watcher-history-3-2017.09.7","index":"logstash","jsaInnerJso":{"message":"测试数据查看返回值","hostIP":"22.5.254.175"}}]}
