@JsonView不过滤属性(Spring 4.1.0.RC2,Jackson 2.3.2)

标签: java json spring jackson json-view

我有一个实体(使用lombok)和一些带注释的@JsonView注释。

@Entity
@Table(name = "`order`")
@Getter
@Setter
@ToString
@Description("Приказ")
public class Order extends Auditable {


    private static final long serialVersionUID = -1299630493411381582L;

    @JsonView(JsonViews.OrderAdvancedSearch.class)
    @ManyToOne
    private School school;

    @Column(length = 50)
    private String number;
}

有一个用@JsonView注释注释的控制器方法。

@Secured(value = {"ROLE_AUTHENTICATED_USER"})
@RequestMapping(value = "/order", method = RequestMethod.GET, headers = {"Content-Type=application/json"})
@JsonView(JsonViews.OrderAdvancedSearch.class)
@ResponseBody
public ResponseEntity<Order> getOrder(HttpServletRequest request) throws IOException, DnevnikException, RestException {
    Order order = orderRepository.findOne(292L); // just for example
    return new ResponseEntity<>(order,HttpStatus.OK);
}

我预计输入将只包含用@JsonView注释的字段。 但我充满了各种各样的领域。

我正在尝试调试spring和jackson来源。 在com.fasterxml.jackson.databind.SerializationConfig中,我看到活动视图是我的类JsonViews.OrderAdvancedSearch.class 但是在com.fasterxml.jackson.databind.ser.std.BeanSerializerBase变量中,filteredProps总是具有我实体的所有属性。

尝试调整Jackson对象映射器:

// disable this feature so that attributes with no view definition
// do not get serialized / deserialized
mapper.disable(MapperFeature.DEFAULT_VIEW_INCLUSION);

@Attila T的答案已经足够,但我已经发布了如何调整对象映射器并在任何地方使用它的代码

控制器代码:

@Autowired
JSONMapper objectMapper;

@RequestMapping
public ResponseEntity<> getSchoolDetails(ParameterMapper mapper,HttpServletResponse           response) throws JsonGenerationException, JsonMappingException, IOException
{
     Order order =  orderRepository.findOne(292L);
    ObjectWriter w = objectMapper.writerWithView(SomeClass.class);
    objectWriter.writeValue(response.getWriter(),order);
  return new ResponseEntity<>(order,HttpStatus.OK);
}

自定义对象映射器

@Component
public class JSONMapper extends ObjectMapper {


public JSONMapper() {

    Hibernate4Module hm = new Hibernate4Module();
    registerModule(hm);
    configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
    configure(SerializationFeature.INDENT_OUTPUT , false);
    configure(MapperFeature.DEFAULT_VIEW_INCLUSION, false);
    setSerializationInclusion(Include.NON_EMPTY);  
}
}

调度程序配置(相应地更改基于xml的配置)

   @Override
        public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {

            MappingJackson2HttpMessageConverter jsonConvertor = new MappingJackson2HttpMessageConverter(new JSONMapper());
            List<MediaType> jsonMediaTypes =new ArrayList<MediaType>();
            jsonMediaTypes.add(MediaType.APPLICATION_JSON);
            jsonConvertor.setSupportedMediaTypes(jsonMediaTypes);
            converters.add(jsonConvertor);    
            addDefaultHttpMessageConverters(converters);

       }
