代码结构

这里写图片描述

程序清单

AppConfig.java：

package com.wiley.beginningspring.ch3.config;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.view.InternalResourceViewResolver;@Configuration@ComponentScan(basePackages = {"com.wiley.beginningspring.ch3"})public class AppConfig { @Bean public InternalResourceViewResolver getInternalResourceViewResolver() { InternalResourceViewResolver resolver = new InternalResourceViewResolver(); resolver.setPrefix("/WEB-INF/pages/"); resolver.setSuffix(".jsp"); return resolver; }}

web.xml：

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" ><web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"> <display-name>Archetype Created Web Application</display-name> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextClass</param-name> <param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value> </init-param> <init-param> <param-name>contextConfigLocation</param-name> <param-value>com.wiley.beginningspring.ch3.config.AppConfig</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping></web-app>
