@JsonUnwrapped扁平化对象

使用扁平化前

@Getter
@Setter
@ToString
public class Account {
    private Location location;
    private PersonInfo personInfo;

  @Getter
  @Setter
  @ToString
  public static class Location {
     private String provinceName;
     private String countyName;
  }
  @Getter
  @Setter
  @ToString
  public static class PersonInfo {
    private String userName;
    private String fullName;
  }
}

结果

{
    "location": {
        "provinceName":"湖北",
        "countyName":"武汉"
    },
    "personInfo": {
        "userName": "coder1234",
        "fullName": "shaungkou"
    }
}

扁平化之后

@Getter
@Setter
@ToString
public class Account {
    @JsonUnwrapped
    private Location location;
    @JsonUnwrapped
    private PersonInfo personInfo;
    ......
}

结果

{
  "provinceName":"湖北",
  "countyName":"武汉",
  "userName": "coder1234",
  "fullName": "shaungkou"
}
