SSM项目的环境搭建：

一、项目的目录结构如下：

![Image 1][]![Center][]

二、导入的jar包：WEB-INF/lib下

![Image 1][]

![Center 3][]

三、resources下的几个配置文件+WEB-INF下的web.xml文件需要自己配置：

**wei.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" 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>pmis</display-name>
     
     
    	<filter>
    		<filter-name>characterEncoding</filter-name>
    		<filter-class> org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    		<init-param>
    		  <param-name>encoding</param-name>
    		  <param-value>UTF8</param-value>
    		</init-param>
    	</filter>
    	<filter-mapping>
    		<filter-name>characterEncoding</filter-name>
    		<url-pattern>/*</url-pattern>
    	</filter-mapping>
      
      
      
      <listener>
          <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
      
      <context-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:beans.xml</param-value>
      </context-param>
      
      
      
      <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>
      </servlet>
      <servlet-mapping>
          <servlet-name>springmvc</servlet-name>
          <url-pattern>*.do</url-pattern>
      </servlet-mapping>
     
      <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
      </welcome-file-list>
    </web-app>

beans.xml

mybatis.xml

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE configuration
    PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
    "http://mybatis.org/dtd/mybatis-3-config.dtd">
    <configuration>
    
    </configuration>

其中，配置数据源时，用到的数据库连接的资源文件jdbc.properties:
    jdbc.url = jdbc\:mysql\://localhost:3306/lanou
    jdbc.driver = com.mysql.jdbc.Driver
    jdbc.username= root
    jdbc.password= 123456

日志文件log4j.properties（不需要自己手写）
    log4j.rootLogger=debug,stdout,logfile
    ### \u628A\u65E5\u5FD7\u4FE1\u606F\u8F93\u51FA\u5230\u63A7\u5236\u53F0 ###
    log4j.appender.stdout=org.apache.log4j.ConsoleAppender
    #log4j.appender.stdout.Target=System.err
    log4j.appender.stdout.layout=org.apache.log4j.SimpleLayout
    ### \u628A\u65E5\u5FD7\u4FE1\u606F\u8F93\u51FA\u5230\u6587\u4EF6\uFF1Ajbit.log ###
    log4j.appender.logfile=org.apache.log4j.FileAppender
    log4j.appender.logfile.File=D:/test.log
    log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
    log4j.appender.logfile.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %F %p %m%n
     
    ###\u663E\u793ASQL\u8BED\u53E5\u90E8\u5206
    log4j.logger.com.ibatis=DEBUG
    log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG
    log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG
    log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG
    log4j.logger.java.sql.Connection=DEBUG
    log4j.logger.java.sql.Statement=DEBUG
    log4j.logger.java.sql.PreparedStatement=DEBUG
    log4j.logger.java.sql=debug

四、编写一个测试类：SSMTest.java

package cn.com.lanou.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    @Controller
    public class SSMTest {
    
    	@RequestMapping("/SSMtest")
    	public String test(){
    		return "HelloSSM";
    	}
    	
    }

返回视图：HelloSSM.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
        pageEncoding="UTF-8"%>
    <!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=UTF-8">
    <title>Insert title here</title>
    </head>
    <body>
    <h1>Hello SSM.....</h1>
    </body>
    </html>
