我正在尝试创建一个简单的Spring 3应用程序,并拥有以下文件。请告诉我这个错误的原因。
以下是我的web.xml文件。
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

id="WebApp_ID" version="3.0">
<display-name>Spring2</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>

</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
以下是我的index.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

<body>
Index Page<br/>
<form:form commandName="loginBean" method="POST" action="login">
<form:input path="userName" id="userName"/><br/>
<form:input path="password" id="password"/><br/>
<input type="submit" value="submit"/>
</form:form>
<a href="register.jsp">Go to Registration Page</a>
</body>
</html>
这里是我的dispatcher-servlet.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/" />
<property name="suffix" value=".jsp" />
</bean>
<bean name="/login" class="com.infy.controller.LoginController"/>
</beans>
这是LoginController.java文件
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class LoginController {
@RequestMapping(value="/login", method=RequestMethod.POST)
public ModelAndView loginAction(@ModelAttribute("loginBean")LoginBean bean){
return new ModelAndView("success", "success", "Successful Login");
}
}
最后是我的LoginBean
public class LoginBean {
private String userName;
private String password;
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
applicationContext.xml
