1. 新建Web project
SSM框架搭建——我的第一个SSM项目
2. 添加ljar文件

3. web.xml文件

添加Source Foled 名称为config，添加如下文件
新建package

6.mybatis配置文件下的sqlMapConfig.xml文件

<?xml version="1.0" encoding="UTF-8" ?>

    </typeAliases>

    <!-- 配置mapper
    由于使用spring和mybatis的整合包进行mapper扫描，这里不需要配置了。
    必须遵循：mapper.xml和mapper.java文件同名且在一个目录
     -->

数据库连接信息db.properties

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

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

编写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;
}
}

在web-inf下新建jsp文件夹，添加index.jsp文件

<%@ 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>

14.发布网站，在浏览器输入 http://localhost:8080/FirstSSM/Index即可
