作者使用MyEclipse 2014版本
本博客所编写程序源码为：

1. 新建Web project
2. 添加ljar文件
3. web.xml文件
<?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_3_0.xsd" id="WebApp_ID" version="3.0">

</listener>
<!-- springmvc前端控制器，rest配置 -->
<servlet>
<servlet-name>springmvc_rest</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- contextConfigLocation配置springmvc加载的配置文件（配置处理器映射器、适配器等等） 如果不配置contextConfigLocation，默认加载的是/WEB-INF/servlet名称-serlvet.xml（springmvc-servlet.xml） -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/springmvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>

<url-pattern>/</url-pattern>
</servlet-mapping>

<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>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" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!-- 全局setting配置，根据需要添加 -->
<!-- 配置别名 -->
<typeAliases>
<!-- 批量扫描别名 -->
<package name="com.ssm.po"/>
</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
-->
<!-- <mappers>
</mappers> -->
</configuration>- spring下的applicationContext-dao.xml

<!-- 可以扫描controller、service、...

<!--注解映射器 -->
<!-- <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/> -->
<!--注解适配器 -->
<!-- <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"/> -->
<!-- 使用 mvc:annotation-driven代替上边注解映射器和注解适配器配置
mvc:annotation-driven默认加载很多的参数绑定方法，
比如json转换解析器就默认加载了，如果使用mvc:annotation-driven不用配置上边的RequestMappingHandlerMapping和RequestMappingHandlerAdapter
实际开发时使用mvc:annotation-driven
-->
<mvc:annotation-driven ></mvc:annotation-driven>
<!-- 视图解析器
解析jsp解析，默认使用jstl标签，classpath下的得有jstl的包
-->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<!-- 设置上传文件的最大尺寸为5MB -->
<property name="maxUploadSize">
<value>5242880</value>
</property>
</bean>
</beans>- 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
至此，第一个SSM项目已经编写完成！
