要求：打印出数据库的sql语句日志
这里要强调的是，这里的数据库配置是直接放在了spring-mybatis.xml中，所以mybatis-config.xml是为了打印数据库日志单独加的
下面是mybatis-config.xml的内容：
<?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> <setting name="logImpl" value="LOG4J"/> </settings> </configuration>
下面是spring-mybatis.xml的内容：
