Question

我尝试将请求从WildFly 8.1中的Rest方法转发到JSP页面，但这会抛出异常：

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），但是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，使其具有属性allow-non-standard-wrappers="true"。

有关详细信息，请查看the official documentation（Servlet container configuration部分）。

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