MybatisXml的相关配置

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"?>
