java - Jersey Web 服务发送 415 状态代码

Question

我已经使用 jersey 为使用 servlet 创建的 Jave EE Web 应用程序创建了一个 Web 服务。我发现我收到 415 错误代码。

我通常会重定向到另一个 servlet 或重定向到 jsp(从技术上讲，它是我的应用程序中的 servlet)。我应该使用哪种 mime-type使用？

  SEVERE: A message body reader for Java class javax.servlet.http.HttpServletRequest,   and Java type interface javax.servlet.http.HttpServletRequest, and MIME media type application/octet-stream was not found.
   The registered message body readers compatible with the MIME media type are:
   application/octet-stream ->
   com.sun.jersey.core.impl.provider.entity.ByteArrayProvider
   com.sun.jersey.core.impl.provider.entity.FileProvider
   com.sun.jersey.core.impl.provider.entity.InputStreamProvider
   com.sun.jersey.core.impl.provider.entity.DataSourceProvider
   com.sun.jersey.core.impl.provider.entity.RenderedImageProvider
   */* ->

这是 Google Chrome 中的网络选项卡:

更新:

删除了代码的所有注释并将 servlet 添加到 web.xml 文件中:

是否建议使用我的 servlet 包作为 Web 服务的包？

Answer 1

将 @Context 属性添加到服务方法的 HttpServletRequest 参数
