1. 新增Source Foled 名稱為config，新增如下檔案
   

2. 新建package
   
   6.mybatis配置檔案下的sqlMapConfig.xml檔案

<?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>

    <!-- 全域性setting配置，根據需要新增 -->

    <!-- 配置別名 -->
    <typeAliases>
        <!-- 批量掃描別名 -->
        <package name="com.ssm.po"/>
    </typeAliases>

    <!-- 配置mapper
    由於使用spring和mybatis的整合包進行mapper掃描，這裡不需要配置了。
    必須遵循：mapper.xml和mapper.java檔案同名且在一個目錄 
     -->

    <!-- <mappers>

    實際開發時使用mvc:annotation-driven
     -->
    <mvc:annotation-driven ></mvc:annotation-driven>

    <!-- 檢視解析器
    解析jsp解析，預設使用jstl標籤，classpath下的得有jstl的包

1. 資料庫連線資訊db.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mybatis
jdbc.username=root
jdbc.password=mysql

1. log4J配置 log4j.properties

# Global logging configuration\uff0c\u5efa\u8bae\u5f00\u53d1\u73af\u5883\u4e2d\u8981\u7528debug
log4j.rootLogger=DEBUG, stdout
# 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

1. 編寫FirstController

package com.ssm.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class FirstController {
@RequestMapping("Index")
public ModelAndView index(){
    ModelAndView mav = new ModelAndView();
    mav.addObject("hello", "Hello world!");
    mav.setViewName("index");
    return mav;
}
}

1. 在web-inf下新建jsp資料夾，新增index.jsp檔案

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
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>My JSP 'index.jsp' starting page</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">
    <!--
    <link rel="stylesheet" type="text/css" href="styles.css">
    -->
  </head>

  <body>
   ${hello}<br>
  </body>
</html>

至此，第一個SSM專案已經編寫完成！
