Question

这是一个非常简单的代码，我正在努力开始使用Spring MVC，我已经尝试了解决这个问题的所有选项，但我无法做到。 Code运行正常以显示index.jsp（它告诉我DispatcherServlet和ViewResolver都正常工作），但是当我单击“LoginForm”以显示Login Form（loginform.jsp）以便用户可以提交用户名时和密码我得到以下异常。

       Here is what I am getting when I run my code

    "Sep 02, 2014 2:56:49 PM   org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver handleHttpRequestMethodNotSupported
    WARNING: Request method 'GET' not supported"

我非常感谢任何帮助。

以下是我的代码的一些部分

这是我的控制器

@Controller
public class LoginController {
    @RequestMapping(value = "/loginForm", method = RequestMethod.GET)
        public String showForm(Map model) {
                LoginForm loginForm = new LoginForm();
                model.put("loginForm", loginForm);
                return "/login/loginform";
        }
}

的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

        </init-param>

   </servlet>

   <servlet-mapping>
      <servlet-name>firstMvc</servlet-name>
      <url-pattern>/</url-pattern>
   </servlet-mapping>

</web-app>

index.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"

loginForm.jsp中

<body>

    <h3>Login Form</h3>

    </FONT>
    <form:form action="loginform.html" commandName="loginForm">
        <table>
            <tr>
                <td>User Name:<FONT color="red"><form:errors
                            path="userName" /></FONT></td>
            </tr>
            <tr>
                <td><form:input path="userName" /></td>
            </tr>
            <tr>
                <td>Password:<FONT color="red"><form:errors

            </tr>
            <tr>
                <td><form:password path="password" /></td>
            </tr>
            <tr>
                <td><input type="submit" value="Submit" /></td>
            </tr>
        </table>
      </form:form>
      </body>

春天你不必* .html。只需使用控制器值。在views.xml中，您必须将值设置为jsp文件。

<form:form action="/loginform" commandName="loginForm">
        <table>
            <tr>
                <td>User Name:<FONT color="red"><form:errors
                            path="userName" /></FONT></td>
            </tr>
            <tr>
                <td><form:input path="userName" /></td>
            </tr>
            <tr>
                <td>Password:<FONT color="red"><form:errors
                            path="password" /></FONT></td>
            </tr>
            <tr>
                <td><form:password path="password" /></td>
            </tr>
            <tr>
                <td><input type="submit" value="Submit" /></td>
            </tr>
        </table>
      </form:form>

SpringMVC请求方法'GET'不受支持？
