从REST访问请求对象

在JAX-RS上,您必须注释 Request 参数与 @Context :

 @GET  
 public Response foo(@Context Request request) {

 }

也可以选择注入:

• UriInfo
• HttpHeaders
• SecurityContext
• HttpServletRequest

为了详细说明@dfa对备选方案的回答,我发现这比在每个资源方法签名上指定变量要简单:

public class MyResource {

  @Context
  private HttpServletRequest httpRequest;

  @GET  
  public Response foo() {  
    httpRequest.getContentType(); //or whatever else you want to do with it
  }
}
