我尝试将请求从 WildFly 8.1 中的 Rest 方法转发到 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
    at io.undertow.servlet.spec.RequestDispatcherImpl.forward(RequestDispatcherImpl.java:103) [undertow-servlet-1.0.15.Final.jar:1.0.15.Final]

编码:

@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);
}

此代码在 Jboss 7.1 中没有问题。

我没有进行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),但是在 Undertow 中有一个选项可以禁用它:

standalone/configuration/standalone.xml文件中更改servlet-containerXML 元素,使其具有属性allow-non-standard-wrappers="true"

有关详细信息,请查看官方文档(the Servlet container configurationsection)。
