最终编辑
所以经过研究,因为答案并没有因为我看到的,我发现,春天做一些奇怪的东西与扩展匹配.如果我提交了一个这样的请求,通过NameOrAtlName / myStringHere.1或者这个byNameOrAtlName / myStringHere.12,一切都很好,但是ByNameOrAtlName / myStringHere.123导致它与ByNameOrAtlName / myStringHere.com一样,但是byNameOrAtlName / myStringHere.co就可以,但是byNameOrAtlName / myStringHere.c不是. 总而言之,我不知道什么逻辑弹簧用来确定扩展的东西,但对于某些扩展名{varName：. }作为一种工作,但它看起来像您需要完全禁用点文件后缀来真正了解它. 使用Spring 4.1.6 Spring抛出以下异常org.springframework.web.HttpMediaTypeNotAcceptableException：找不到可接受的表示 我有以下代码,一切正常,除非字符串(名称)中有一个句点. @RestController
@RequestMapping(value = "/foo/")
public class Testing{
@RequestMapping(value = "byNameOrAltName/{name:.+}",method = RequestMethod.GET)
@Transactional(readOnly = true)
public Collection<MyDTO> getByNameOrAltNAme(@PathVariable("name") String name) {
return myRepo.getMyDTOsByNameOrAtlName(name);
}
}
所以这样做. http：// localhost：8080 / data / foo / byNameOrAtlName / myStringHere,但是如果我这样做,则失败http：// localhost：8080 / data / foo / byNameOrAtlName / myStringHere.fluffy 我读了关于这个例外的其他答案,但他们似乎都不适用于我的例子.起初我以为这是春天不喜欢时代的问题,而且我正是用正则表达式修正的.但是我尝试使用和不使用正则表达式,我得到相同的错误. 有什么想法为什么Spring会抛出这个？ 编辑 这是我的调试日志： 21:32:09,118 DEBUG work.orm.jpa.support.OpenEntityManagerInViewFilter: 161 -

Spring正在将点后的部分视为文件后缀,以尝试确定您实际想要的响应类型.
Here是Spring中内容谈判的体面写作.
那么发生什么事情是Spring正试图将结果呈现给一个内容类型,它找不到转换器. 要解决这个问题,你需要告诉spring关闭基于后缀的内容谈判： @Configuration
public class ContentNegotiationConfig extends WebMvcConfigurerAdapter {
@Override
void configureContentNegotiation(final ContentNegotiationConfigurer configurer) {
// Turn off suffix-based content negotiation
configurer.favorPathExtension(false);
}
}
更新： 我已经挖了一点,我想我可以解释发生了什么. 默认配置忽略未知的路径后缀,因此要解释这一点,我们需要知道Spring如何确定路径后缀是未知的,并且在PathExtensionContentNegotiationStrategy中归结为这段代码： @Override
protected MediaType handleNoMatch(NativeWebRequest webRequest,String extension)
throws HttpMediaTypeNotAcceptableException {
if (this.useJaf) {
MediaType jafMediaType = JafMediaTypeFactory.getMediaType("file." + extension);
if (jafMediaType != null && !MediaType.APPLICATION_OCTET_STREAM.equals(jafMediaType)) {
return jafMediaType;
}
}
if (!this.ignoreUnknownExtensions) {
throw new HttpMediaTypeNotAcceptableException(getAllMediaTypes());
}
return null;
}
那么发生了什么事情可能是Java Activation Framework正在识别你的某些后缀并为它们返回一个媒体类型 – .c扩展名可能会返回text / x-c,因为这会导致异常. （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
