不支持内容类型的内部服务器错误

Question

我已经构建了一个RESTendpoint，它使用Spring和Apache CXF2.5来使用和生成Application/JSON。

@POST
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Response search(MyPostedObject obj) {
  ...
}

配置：

<jaxrs:server id="myEndPoint" address="/myendpoint" >
    <jaxrs:serviceBeans>
        <ref bean="myrestservice" />
    </jaxrs:serviceBeans>
    <jaxrs:providers>               
        <bean class="org.codehaus.jackson.jaxrs.JacksonJsonProvider"/>
    </jaxrs:providers>
</jaxrs:server>

当我使用不受支持的内容类型（如application/xml）发送请求（使用REST客户端应用程序）时，我会得到一个内部服务器错误。我希望是405，因为endpoint不支持任何其他内容类型。为什么我会得到这个例外？

Answer 1

我相信我找到了答案。我使用的是Apache CXF的2.5.11版本，它似乎不完全符合javax.ws.rs-api2.0。相反，我切换到JSR311-API，现在一切都像例外一样工作。
