json 字串解析

今天遇到一個請求json字串,格式如下

{"data":"{\"applyId\":\"123456\",\"status\":\"1\",\"result\":\"報備成功\"}","requestId":"123456","version":"1.0","timestamp":"2021-01-12 10:10:52.670"}

分析:

這個字串由data、其他欄位組成,其中data部分是帶轉義字元\的.

可見這個請求其實包含了兩個json串,一個是請求本身,一個是內部的data,所以對於內部的data要再進行一次解析轉換

{
    "data":"{"applyId":"123456","status":"1","result":"報備成功"}",
 

    "requestId":"123456",
    "version":"1.0",
    "timestamp":"2021-01-12 10:10:52.670"
}

方法1:

public void notice(@RequestBody String request){
　　JSONObject json = JSONObject.parseObject(request);
　　String dataStr = json.getString("data");
　　NoticeDO data = JSONObject.parseObject(dataStr,NoticeDO.class);
}

NoticeDo實體

public class NoticeDO {
    private String applyId;
    private String status;
    private String result;
}

方法2:

public void notice(@RequestBody NoticeReq request){
　　// 對data進行解析
　　NoticeDO data = JSONObject.parseObject(request.getData(),NoticeDO.class);
}

NoticeReq 實體類

public class NoticeReq {
    private String requestId;
    private String version;
    private String timestamp;
    private String data;
}
