SSM 框架的搭建

1、新建一个web项目 

 

2、新建包和添加配置文件

 

 

3、修改配置文件 applicationContext.xml

配置文件 mybatis.config.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>
    <settings>
        <!-- 打印查询语句 -->
        <setting name="logImpl" value="STDOUT_LOGGING" />
    </settings>
</configuration>

 

 

 

生成数据库中映射的文件

 

把生成的文件放进项目中

 

 

配置 web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

添加 jre

添加服务，然后启动，这样就搭建成功一个SSM框架
