rest – 请求io.undertow.servlet.spec.HttpServletRequestImpl不是原始的或包装器

我尝试将请求转发到WildFly 8.1中的Rest方法的JSP页面,但这会引发异常:

Caused by: java.lang.IllegalArgumentException: UT010023: Request io.undertow.servlet.spec.HttpServletRequestImpl@88ad706 was not original or a wrapper

代码:

@GET
@Path("/my-path")
public void myRestMethod(@Context final HttpServletResponse response,
        @Context final HttpServletRequest request) throws ServletException, IOException {

     RequestDispatcher dispatcher = request.getRequestDispatcher("/path/to/jsp");
     dispatcher.forward(request, response);
}

这段代码在Jboss 7.1中没有问题.

我没有足够的调试来理解为什么/何时添加了这些检查(显然这是Servlet规范所要求的),但Undertow中有一个选项可以禁用它:

在standalone / configuration / standalone.xml文件中,更改servlet-container XML元素,使其具有allow-non-standard-wrappers =“true”属性.

有关详细信息,请检查the official documentation(Servlet容器配置部分).
