Question

当我在Tomcat 7.0服务器上运行我的应用程序时，我的 index.jsp 文件被执行，如果我点击 LOGIN（href）到 loginPage .jsp 它不会被执行。

我的TOMCAT中出现了以下错误，因为请求的资源不可用。我已经搜索了很多但是仍然无法摆脱这个。

实际上是尝试使用 java4sController.java和UserDetails.java类来验证我的 loginPage.jsp 文件。

我的web.xml

我的Tomcat7.0出错。。

   HTTP Status 404 - /Mvcvalid/displayForm.htm

--------------------------------------------------------------------------------

type Status report

message /Mvcvalid/displayForm.htm

description The requested resource is not available.


--------------------------------------------------------------------------------

Apache Tomcat/7.0.42

Answer 1

尝试删除UserDetails作为

方法的参数

@RequestMapping(value="displayForm", method=RequestMethod.GET)
    public String helloWorld(UserDetails ud) {
        return "loginPage";            
    }

希望这能解决它。

请求不由DispatcherServlet处理＆＃34; HTTP状态404 - /Mvcvalid/displayForm.html（请求的资源不可用）＆＃34;
