泽西岛没有捕获异常

Question

我对 ExceptionMapper 的实现如下所示：

@Provider
public class CaptureUnhandledExceptions implements ExceptionMapper<Throwable>
{
    private static final Logger LOGGER = LogFactory.getLogger(CaptureUnhandledExceptions.class);

    @Override
    public Response toResponse(Throwable exception)
    {
        LOGGER.error("Unhandled exception", exception);
        ErrorMessage em = new ErrorMessage(50099, ExceptionUtils.getRootCause(exception).getMessage(),
                exception.getMessage());
        return Response.status(Response.Status.INTERNAL_SERVER_ERROR).entity(em).build();
    }
}

在我的 REST api 中，我试图为我的 JSON 主体传递错误的值，但它抛出以下异常

Can not deserialize value of type com.abccompany.model.ConnectionEndpoint$Binding from String "RandomValue: value not one of declared Enum instance names: [POST, REDIRECT]
 at [Source: org.glassfish.jersey.message.internal.ReaderInterceptorExecutor$UnCloseableInputStream@3fce79f3; line: 16, column: 28] (through reference chain: com.abccompany.model.SpConnection["connection"]->com.abccompany.model.Connection["connectionendpoints"]->java.util.ArrayList[0]->com.abccompany.model.ConnectionEndpoint["endpointbinding"])

我错过了什么？我是否必须在 ResourceConfig 中注册我的提供商？

在应用的ResourceConfig中

this.register(com.abccompany.utils.CaptureUnhandledExceptions.class);

Answer 1

解决方法是在 ResourceConfig

中添加 this.register(com.fasterxml.jackson.jaxrs.json.JacksonJaxbJs‌onProvider.class);
