Java中用fastjson对String、JSONObject、JSONArray相互转换

fastjson是阿里巴巴的开源JSON解析库，它可以解析JSON格式的字符串，支持将Java Bean序列化为JSON字符串，也可以从JSON字符串反序列化到JavaBean

下面主要是本人在工作中经常用到的关于String、JSONObject、JSONArray的相互装换

• String——>>>JSONArray

String st = "[{name:Tim,age:25,sex:male},{name:Tom,age:28,sex:male},{name:Lily,age:15,sex:female}]";
JSONArray tableData = JSONArray.parseArray(st);

• JSONArray——>>>JSONObject

JSONObject rowData = new JSONObject();
for(int i;i

• String——>>>JSONObject

String st = "{name:Tim,age:25,sex:male}";
JSONObject rowData = JSONObject.parseObject(st);

• JSONObject——>>>JSONArray

JSONObject rowData = {info:
                            [
                                {
                                    name:Tim,
                                    age:25,
                                    sex:male
                                },{
                                    name:Tom,
                                    age:28,
                                    sex:male
                                },{
                                    name:Lily,
                                    age:15,
                                    sex:female
                                }
                            ]
                        };
JSONArry tableData = rowData.get("info");
