1.建立maven專案
2.配置pom.xml檔案

3.資料庫配置:database.properties

driver=com.mysql.jdbc.Driver
url=jdbc:mysql:///mysql
username=root
password=root

4.mybatis配置檔案:mybatis-config.xml

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

    "http://mybatis.org/dtd/mybatis-3-config.dtd">

    <!-- 註冊對映元檔案 -->
    <mappers>
        <mapper resource="com/lq/mapper/UserBeanMapper.xml"/>
    </mappers>
</configuration>

5.日誌輸出配置:log4j.properties

log4j.rootLogger=ALL, Console
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=%m%n


log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
log4j.logger.java.sql.ResultSet=INFO

6.反向工程檔案配置:generator.xml

<!DOCTYPE generatorConfiguration
