@Data
public class Account {
@JsonUnwrapped
private Location location;
@JsonUnwrapped
private PersonInfo personInfo;
@Data
public static class Location {
private String provinceName;
private String countyName;
}
@Data
public static class PersonInfo {
private String userName;
private String fullName;
}
}
未扁平化之前：
{
"location": {
"provinceName":"广东",
"countyName":"深圳"
},
"personInfo": {
"userName": "111",
"fullName": "222"
}
}
使用 @JsonUnwrapped 扁平对象之后：
{
"provinceName":"广东",
"countyName":"深圳",
"userName": "111",
"fullName": "222"
}
不同对象间有相同名称的属性？会怎么样，会报错吗？答案是不会，都会正常返回，只是对前端而言有歧义罢了~，此时可以借助
@JsonUnwrapped的 suffix 和 prefix 来规避这个问题
