我试图将请求从WildFly 8.1中的Rest方法转发到JSP页面,但这引发了异常:
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中运行得很顺利。
我没有进行足够的调试,无法理解为什么/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,使其具有属性allow-non-standard-wrappers="true"
。
有关详细信息,请查看官方文档(Servlet container configuration
部分)。
