想要配置Mybatis，至少需要三个文件与jar包
其中，dbconfig.properties存放的是连接数据库的相关数据
driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/springmvx?characterEncoding=utf-8
user=root
psw=root123
log4j.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<appender name="STDOUT" class="org.apache.log4j.ConsoleAppender">
<param name="Encoding" value="GBK" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p %d{MM-dd HH:mm:ss,SSS} %m (%F:%L) \n" />
</layout>
</appender>
<logger name="java.sql">
<level value="debug" />
</logger>
<logger name="org.apache.ibatis">
<level value="info" />
</logger>
<root>
<level value="debug" />
<appender-ref ref="STDOUT" />
</root>
</log4j:configuration>
resource.xml中则是配置所需要的属性:
<?xml version="1.0" encoding="UTF-8"?>
