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> ${message} </body> </html>
index.jsp可以很好地启动,但是当我单击导航到登录页面时,我得到404。我使用的是Tomcat7。由于想法不清,看来DispatcherServlet由于某种原因未被调用。
可能是什么问题呢?
提前致谢。
问题可能是您缺少页面中的上下文路径,请尝试以下方式:
<a href="${pageContext.request.contextPath}/Login">login</a>
更新:
您能否也添加 <mvc:annotation-driven/>到您的main-servlet.xml
<mvc:annotation-driven/>
