Json 在Jersey中重写MessageBodyReader以包装反序列化过程

json rest serialization jersey

Json 在Jersey中重写MessageBodyReader以包装反序列化过程,json,rest,serialization,jersey,jackson,Json,Rest,Serialization,Jersey,Jackson,我有一个使用Grizzly、Jersey和Jackson stack的restful服务。如果我在请求中提供了错误的输入值，例如：一个随机字符串而不是UUID，那么Jackson会抛出一个无效的格式或无法识别的属性异常。出于安全目的，我为大多数通用异常添加了异常映射程序，以隐藏异常详细信息。但对于这种非常特殊的情况，如果用户提供了错误的数据，反序列化失败，我想向用户反馈调用失败的原因我认为，如果我可以包装从Jersey到Jackson的反序列化调用，那么我可以抛出一个带有适当数据的自定义异常，

我有一个使用Grizzly、Jersey和Jackson stack的restful服务。如果我在请求中提供了错误的输入值，例如：一个随机字符串而不是UUID，那么Jackson会抛出一个无效的格式或无法识别的属性异常。出于安全目的，我为大多数通用异常添加了异常映射程序，以隐藏异常详细信息。但对于这种非常特殊的情况，如果用户提供了错误的数据，反序列化失败，我想向用户反馈调用失败的原因

我认为，如果我可以包装从Jersey到Jackson的反序列化调用，那么我可以抛出一个带有适当数据的自定义异常，并为自定义异常添加一个映射器

因此，我创建了一个新类，该类重写JacksonJaxbJsonProvider，并将包装器代码添加到readFrom

@Provider
@Consumes(MediaType.WILDCARD) // NOTE: required to support "non-standard" JSON variants
@Produces(MediaType.WILDCARD)
public class JacksonJaxbJsonProviderOverride extends JacksonJaxbJsonProvider {
  private static final Logger logger = LoggerFactory.getLogger(JacksonJaxbJsonProviderOverride.class);

  @Override
  public Object readFrom(
      Class<Object> type,
      Type genericType,
      Annotation[] annotations,
      MediaType mediaType,
      MultivaluedMap<String, String> httpHeaders,
      InputStream entityStream)
      throws IOException {
    try {
      return super.readFrom(type, genericType, annotations, mediaType, httpHeaders, entityStream);
    } catch (Exception ex) {
      throw new ObjectDeserializationException(ex.getMessage());
    }
  }

但是对反序列化的调用不会影响覆盖。你有没有想过为什么会这样

看起来不像是完整的stacktrace。你能把整件事都贴出来吗？顺便说一下，错误响应是由ExceptionMappers发送的。Jackson为JsonMappingException和JsonParseException提供了一个。您不能注册这些，也不能注册您的own@peeskillet我添加了完整的堆栈跟踪。ExceptionMappers不起作用，因为我在其他地方使用Jackson进行序列化/反序列化。如果为每个序列化/反序列化添加异常映射器，则可能会向用户泄漏信息。我想告诉Jersey，只有在反序列化过程中，如果它抛出错误，然后将其包装到自定义异常中，我可以为其添加异常映射器。可能有不同的方法来执行此操作。configure（反序列化功能。wrap_EXCEPTIONS，false）；也许这会有帮助。。。
