Spring MVC Hello World应用程序无法正常工作

我是Spring MVC的新手,我正在尝试编写一个简单的Web应用程序以开始使用Spring。

这是我所拥有的:

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"

xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

id="WebApp_ID" version="2.5">

<display-name>HatifimWeb</display-name>

<welcome-file-list>

<welcome-file>index.jsp</welcome-file>

</welcome-file-list>

<servlet>

<servlet-name>main</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>main</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>

</web-app>

main-servlet.xml

<?xml version="1.0" encoding="UTF-8"?> 

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.0.xsd">

<context:component-scan base-package="springapp.controller" />

<bean id="viewResolver"

class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<property name="viewClass"

value="org.springframework.web.servlet.view.JstlView" />

<property name="prefix" value="/WEB-INF/jsps/" />

<property name="suffix" value=".jsp" />

</bean>

</beans>

LoginController.java

package springapp.controller;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.servlet.ModelAndView;

@Controller

public class LoginController {

@RequestMapping("/Login")

public ModelAndView handleRequest() throws Exception {

System.out.println("Login...");

return new ModelAndView("Login", "message", "test");

}

}

index.jsp

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

pageEncoding="ISO-8859-1"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

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

<title>Insert title here</title>

</head>

<body>

Hello.

<br />

<a href="Login">login</a>

</body>

</html>

Login.jsp

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

pageEncoding="ISO-8859-1"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

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

<title>poopidipoo</title>

</head>

<body>

${message}

</body>

</html>

index.jsp可以很好地启动,但是当我单击导航到登录页面时,我得到404。我使用的是Tomcat7。由于想法不清,看来DispatcherServlet由于某种原因未被调用。

可能是什么问题呢?

提前致谢。

回答:

问题可能是您缺少页面中的上下文路径,请尝试以下方式:

<a href="${pageContext.request.contextPath}/Login">login</a>

您能否也添加 <mvc:annotation-driven/>到您的main-servlet.xml
