问题 (Question)

I am getting the following warning: Request method 'POST' not supported.

Controller method:

@Controllerpublic class UserServiceController {@RequestMapping(value = "/login", method = RequestMethod.POST)@Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class)public String login(@RequestParam Map<String,String> requestParams) throws Exception{    System.out.println(requestParams.values());    loginService.userAuthentication(requestParams.get("loginuname"), requestParams.get("loginpassword"));    System.out.println("Before return");    return "static/profile.html";}}

Dispatcher-servlet.xml

<mvc:resources mapping="/static/**" location="/WEB-INF/static/" />

index.html

<script language="javascript" type="text/javascript">function submitForm(){    document.login.submit();}</script><div id="login" class="login">   <form action="http://localhost:8080/SampleApp/login" name="login" method="post">      <input type="text" value = "Email" name="loginuname" id="loginuname" class="loginbasetxt">      <input type="text" value="Password" name="loginpassword" id="loginpassword" class="loginbasetxt">      <img src="static/img/tb-login-button.png" onclick="submitForm()"/></form>  </div>

However, if i would change the method=RequestMethod.GET and correspondingly at login page then it would work.

Please note, problem is at return "static/profile.html";

FYI location of profile.html is WEB-INF/static/

Thanks!!

我得到以下警告：请求方法后不。

控制器的方法：

@Controllerpublic class UserServiceController {@RequestMapping(value = "/login", method = RequestMethod.POST)@Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class)public String login(@RequestParam Map<String,String> requestParams) throws Exception{    System.out.println(requestParams.values());    loginService.userAuthentication(requestParams.get("loginuname"), requestParams.get("loginpassword"));    System.out.println("Before return");    return "static/profile.html";}}

dispatcher-servlet.xml

<mvc:resources mapping="/static/**" location="/WEB-INF/static/" />

index.html

<script language="javascript" type="text/javascript">function submitForm(){    document.login.submit();}</script><div id="login" class="login">   <form action="http://localhost:8080/SampleApp/login" name="login" method="post">      <input type="text" value = "Email" name="loginuname" id="loginuname" class="loginbasetxt">      <input type="text" value="Password" name="loginpassword" id="loginpassword" class="loginbasetxt">      <img src="static/img/tb-login-button.png" onclick="submitForm()"/></form>  </div>

然而，如果我能改变的方法requestmethod.get对应在登录页面，然后它会工作。

请注意，问题是返回“静态HTML /配置文件。”；

仅供参考位置profile.html是WEB-INF /静态/

谢谢！！

最佳答案 (Best Answer)

When you POST a form to an HTTP server, the form's contents aren't sent as query parameters; instead, the form is (usually) uploaded as an entity of type application/x-www-form-urlencoded. Instead of using @RequestParam in your method, define a Java class that has fields corresponding to the form fields, and use @ModelAttribute FormClass form.

当你POST一个形成一个HTTP服务器，表单的内容不是作为查询参数发送；相反，形式（通常）作为实体类型上传application/x-www-form-urlencoded。而不是使用@RequestParam在你的方法，定义了一个Java类，对应于形成域域，并使用@ModelAttribute FormClass form。

答案 (Answer) 2

you should try this:

return "forward:/static/profile.html";

你应该试试这个：

return "forward:/static/profile.html";
