**2.创建log4j.properties**

# Global logging configuration
    log4j.rootLogger=DEBUG, stdout
    # MyBatis logging configuration...
    log4j.logger.org.mybatis.example.BlogMapper=TRACE
    # Console output...
    log4j.appender.stdout=org.apache.log4j.ConsoleAppender
    log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
    log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

**3.创建springmvc.xml \[springmvc的配置文件\]**

5.创建UserController

/**
     * 自定义控制器
     * @author LJH
     *
     */
    public class User01Controller implements Controller{
        
    	
    	@Override
    	public ModelAndView handleRequest(HttpServletRequest request,
    			HttpServletResponse response) throws Exception {
        
    		List<User> users=new  ArrayList<>();
    		for (int i = 1; i <=10; i++) {
        
    			users.add(new User(i, "小明"+i, "武汉"+i, new Date()));
    		}
    		ModelAndView modelAndView=new ModelAndView();
    		//设置要跳转的路径
    		modelAndView.setViewName("list.jsp");  
    		//reqest.getRequestDispatcher("list.jsp")
    		//设置数据
    		modelAndView.addObject("users", users);// 
    		request.setAttribute("users",users)
    		return modelAndView;
    	}
    
    
    
    }

6.创建index.jsp

**7.创建list.jsp**

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
    <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
    <%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
    <%
    	String path = request.getContextPath();
    	String basePath = request.getScheme() + "://"
    			+ request.getServerName() + ":" + request.getServerPort()
    			+ path + "/";
    %>
    
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
    <html>
    <head>
    <base href="<%=basePath%>">
    
    <title>用户列表</title>
    <meta http-equiv="pragma" content="no-cache">
    <meta http-equiv="cache-control" content="no-cache">
    <meta http-equiv="expires" content="0">
    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    <meta http-equiv="description" content="This is my page">
    
    </head>
    
    <body>
    	<h1>
    		所有用户
    	</h1>
    	<hr>
    	<table border="1" width="100%" cellpadding="5" cellspacing="5">
    		<tr>
    			<th>编号</th>
    			<th>姓名</th>
    			<th>地址</th>
    			<th>生日</th>
    		</tr>
    		<c:forEach var="sn" items="${users }">
    			<tr>
    				<td align="center">${
        sn.id }</td>
    				<td align="center">${
        sn.name }</td>
    				<td align="center">${
        sn.address }</td>
    				<td align="center">
    				<fmt:formatDate value="${sn.birth }" pattern="yyyy-MM-dd 
    				HH:mm:ss"/>
    				</td>
    			</tr>
    		</c:forEach>
    	</table>
    	<fmt:formatNumber value="1999.8899912312" pattern="#.##" >
    	</fmt:formatNumber>
    </body>
    </html>

**8.修改springmvc.xml**

<?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" 
    	xmlns:aop="http://www.springframework.org/schema/aop"
    	xsi:schemaLocation="http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans.xsd
                http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/context
    	http://www.springframework.org/schema/context/spring-context.xsd
            ">
       
       
       <bean id="user01Controller" name="/user01Controller.action" 
       class="com.sxt.controller.User01Controller"></bean>
       
    	<bean 
    	class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>
       
       
       
    	<bean 
    	class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>
    	
       
       
       <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
       		
       </bean>
       
       
       
    </beans>

**9.修改web.xml配置前端控制器**

<servlet>
      	<servlet-name>springmvc</servlet-name>
      	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-
      	class>
      	
      	<init-param>
    		<param-name>contextConfigLocation</param-name>
    		<param-value>classpath*:springmvc.xml</param-value>  	
      	</init-param>
      	
      	<load-on-startup>1</load-on-startup>
      </servlet>
      <servlet-mapping>
      	<servlet-name>springmvc</servlet-name>
      	
    		<url-pattern>*.action</url-pattern>
      </servlet-mapping>
