1.web.xml配置

<!--
第一个*代表不仅在class路径查找，还会在jar中的class路径查找；
第二**代表class路径下的任意目录
第三个*任意以application-context开头的文件
-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:**/application-context*.xml</param-value>
</context-param>

<!-- Spring Configuration Spring配置 -->
<listener>
<listener-class>        org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>

2.application-context.xml配置

<?xml version="1.0" encoding="utf-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
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-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd">

<!-- 隐式地向 Spring 容器注册 AutowiredAnnotationBeanPostProcessor、CommonAnnotationBeanPostProcessor、PersistenceAnnotationBeanPostProcessor 以及equiredAnnotationBeanPostProcessor 这 4 个 BeanPostProcessor -->
<context:annotation-config/>

<context:component-scan base-package="com.anonymity.mobile.blog.*"/>
</beans>

3.Service类

package com.anonymity.mobile.blog.service;

import java.util.List;

import com.anonymity.mobile.blog.entity.Users;

public interface UserService {

/**
* 用户列表
* @return
*/
public List<Users> userList();
}

4.ServiceImpl类

package com.anonymity.mobile.blog.serviceimpl;

import java.util.ArrayList;
import java.util.List;

import org.springframework.stereotype.Component;

import com.anonymity.mobile.blog.entity.Users;
import com.anonymity.mobile.blog.service.UserService;

@Component("userServcie")
public class UserServiceImpl implements UserService {

/**
* 用户列表
* @return
* @see com.anonymity.mobile.blog.service.UserService#userList()
*/
@Override
public List<Users> userList() {
List<Users> list = new ArrayList<Users>();
Users u1 = new Users();
u1.setUserName("admin");
u1.setPwd("000000");
Users u2 = new Users();
u2.setUserName("guest");
u2.setPwd("000000");
list.add(u1);
list.add(u2);
return list;
}
}

5.JSP页面

<%@page import="java.util.*"%>
<%@page import="com.anonymity.mobile.blog.entity.*"%>
<html>
<body>
<%
List<Users> userList = (List<Users>)request.getAttribute("userList");
for(Users user:userList){
out.println("<h1>"+user.getUserName()+"</h1>");
}
%>
</body>
</html>

6.备注

6.1调整web.xml配置

<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>

<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*.json</url-pattern>
</servlet-mapping>

6.2调整dispatch-servlet.xml配置

<!--
<mvc:resources mapping="/WEB-INF/jsp/demo/**" location="/WEB-INF/jsp/demo/" cache-period="31556926"/>
-->

InternalResourceViewResolver将视图名解析为一个url，可以理解为转发获取jsp页面。如果使用/*拦截，则需要配置
<mvc:resources mapping="/WEB-INF/jsp/demo/**" location="/WEB-INF/jsp/demo/" cache-period="31556926"/>标签或者 <mvc:default-servlet-handler/>，就可以访问静态资源了。但是这样的话就显示jsp源码了，并没有解析为servlet。所以使用*.html拦截。
