此三个类的作用就是在datasource.xml文件中描述的，把spring与datasource.xml中的datasource和transaction连接起来，此处尤其是“IBatis3SQLSessionFactoryBean”的写法，它通过spring中的“注入”特性，把iBatis的配置注入进spring并委托spring的context来管理iBatis（此属网上没有的资料，全部为本人在历年工程中的经验总结，并且已经在至少3个项目中进行了集成使用与相关测试）。
建立iBatis配置文件
我们先在/src/main/resources目录下建立一个叫sqlmap.xml的文件，内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//ibatis.apache.org//DTD Config 3.0//EN" "http://ibatis.apache.org/dtd/ibatis-3-config.dtd">
<configuration>
<mappers>
<mapper resource="ibatis/index.xml" />
<mapper resource="ibatis/login.xml" />
</mappers>
</configuration>
然后我们在/src/main/resources 目录下建立index.xml与login.x
