Question

在我的Spring Data Rest项目中，我有一个Competition实体，它引用一个GeoLocation实体：

public class Competition {
    @Id
    private String uname;

    [...]

    @NotNull
    @OneToOne(cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.LAZY)
    private GeoLocation geoLocation;
}

public class GeoLocation {
    @Id private Long id;
    private Double latitude;
    private Double longitude;
}

由于每个Competition必须定义一个GeoLocation，因此Competition实体通过cascade处理创建。通过POST创建新的Competition实体时，收到以下响应：

{
    "uname": "Some Competition",
    "geoLocation": {
        [content of geoLocation]
    },
    "_links": {
        [...]
    }
}

但是当我调用新创建的竞赛时，GeoLocation的内容将被包装在content字段中。

{
    "uname": "Some Competition",
    "geoLocation": {
        "content": {
            [content of geoLocation]
        }        
    },
    "_links": {
        [...]
    }
}

我希望这两个请求都能提供相同的响应？

@JsonUnwrapped为我解决了这个问题：

public class Competition {
    @Id
    private String uname;

    [...]

    @NotNull
    @JsonUnwrapped
    @OneToOne(cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.LAZY)
    private GeoLocation geoLocation;
}

Spring Data Rest POST响应与GET响应不同
