Spring整合Mybatis搭建框架步骤

1.建立java项目，创建所需package

2. 引入所需jar文件

3.配置config配置文件

1. Mybatis配置文件

   datasource.properties文件配置

2. configuration.xml文件配置

   <?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>
   <typeAliases>
   <package name="com.wbhz.pojo"/>
   </typeAliases>
   </configuration>

Spring配置文件

applicationContext.xml文件配置

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