spring boot使用jackson处理前端返回的json？-灵析社区
雁过留痕前端返回的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？ 
庆广大拆分嘛，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)
