spring boot使用jackson处理前端返回的json？

Question

前端返回的json如下：

{    "username": {        "__v_isShallow": false,        "dep": {            "w": 0,            "n": 0        },        "__v_isRef": true,        "_rawValue": "1111",        "_value": "1111"    },    "password": {        "__v_isShallow": false,        "dep": {            "w": 0,            "n": 0        },        "__v_isRef": true,        "_rawValue": "12",        "_value": "12"    }}

请问pojo类（如下图）里面相应变量类型应当如何定义？

Answer 1

pojo/Account.java

用内部类配合lombok

package com.xxx.pojo;import lombok.Data;@Datapublic class Account {    private Field username;    private Field password;}@Dataclass Dep {    private int w;    private int n;}@Dataclass Field {    private boolean __v_isShallow;    private Dep dep;    private boolean __v_isRef;    private String _rawValue;    private String _value;}

Answer 2

拆分嘛，嵌套太多层或者感觉乱的时候就拆成多个类不用内部类了，改起来也不会眼花缭乱

public class User2{    private Username username;    private Password password;    //getter、setter方法省略}

public class Username{    private boolean __v_isShallow;    private Dep dep;    private boolean __v_isRef;    private String _rawValue;    private String _value;    //getter、setter方法省略}

public class Password{    private boolean __v_isShallow;    private Dep dep;    private boolean __v_isRef;    private String _rawValue;    private String _value;    //getter、setter方法省略}

public class Dep{    private int w;    private int n;    //getter、setter方法省略}

如果你想实体类属性和json字符串的key值不必一一对应，可以用@JsonProperty注解标在对应的实体类属性上，标在getter和setter上也是可以的(如果要标就一起标上)
