隐藏Jersey RESTful中的JSON字段

问题是我想隐藏RESTFul
JSON响应中的null元素(如果可能的话).

REST控制器从Mongo数据库中检索信息,因为这些元素不存在,我想在它们为空时忽略它们.

这是我的REST控制器(用Jersey公开):

@Stateless
@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
@Path(PropertiesRestURIConstants.PROPERTIES)
@Produces(MediaType.APPLICATION_JSON)
@RequestScoped
public class GetPropertiesController {

    @EJB(mappedName = PropertiesManagerRemote.MAPPED_NAME)
    PropertiesManagerRemote propertiesManager;

    @GET
    @Path(PropertiesRestURIConstants.PROPERTIES_ALL)
    public List<PropertyEntity> getAllProperties() throws DBLayerException {
        return propertiesManager.getAllProperties();
    }

    ...
    ...
    ...
}

这是我的实体:

@Document(collection = "property")
public class PropertyEntity implements GenericEntity {

    @Id
    private String id;

    private String propertyName;
    private String propertyValue;

    public PropertyEntity() {
    }

    public PropertyEntity(String propertyName, String propertyValue) {
        this.propertyName = propertyName;
        this.propertyValue = propertyValue;
    }
...
...
...
}

这就是结果:

[{"id":"542c00c2ff5e0ba4ea58790d","propertyName":"property1","propertyValue":null},{"id":"542c00c2ff5e0ba4ea58790e","propertyName":"property2","propertyValue":null},{"id":"542c00c2ff5e0ba4ea58790f","propertyName":"property3","propertyValue":null}]

我将Spring Data用作持久层.我尝试使用JSONIgnore注释和类似的东西,但没有任何东西适合我.
欢迎任何帮助.

提前致谢.

最佳答案 尝试以这种方式注释:

@JsonInclude(Include.NON_EMPTY)
public class PropertyEntity implements GenericEntity {
