spring-boot/Healthendpoint升级到1.3.0后不支持媒体类型xml

Question

 @Configuration
 public class XStreamMarshallerConfiguration extends WebMvcConfigurerAdapter {

     @Autowired
     private Jackson2ObjectMapperBuilder jackson2ObjectMapperBuilder;

     @Override
     public void configureMessageConverters( final List<HttpMessageConverter<?>> converters ) {
         converters.add( createJsonConverter() ); // support JSON as default (because it is the first)
         converters.add( createXmlHttpMessageConverter() ); // support XStream XML
         super.configureMessageConverters( converters );
     }

     private MappingJackson2HttpMessageConverter createJsonConverter() {
         ObjectMapper jsonMapper = this.jackson2ObjectMapperBuilder.build();
         return new MappingJackson2HttpMessageConverter( jsonMapper );
     }

     private HttpMessageConverter<Object> createXmlHttpMessageConverter() {
         MarshallingHttpMessageConverter xmlConverter = new MarshallingHttpMessageConverter();

         XStreamMarshaller xstreamMarshaller = new XStreamMarshaller();
         configureXStream( xstreamMarshaller.getXStream() ); // my XStream setup

         xmlConverter.setMarshaller( xstreamMarshaller );
         xmlConverter.setUnmarshaller( xstreamMarshaller );

         return xmlConverter;
     }

 }

endpoint只被设计为生成JSON响应。Spring Boot 1.2.x中有一个bug，这意味着如果有合适的转换器可用并且Accept标头要求返回XML，它就可以返回XML，但存在XML格式错误的风险。

Spring Boot1.3通过限制endpoint只生成application/json，而不管可用的HTTP消息转换器是什么来解决这个问题。

如果您希望执行器正式支持XML响应，那么请打开一个增强请求。
