MyBatis Generator使用

这里讲述的是在Maven环境下如何使用，pom全配置

</project>

generatorConfig.xml配置：

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

 "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
	<classPathEntry location="D:/app_data/apache-maven-repository/mysql/mysql-connector-java/5.1.46/mysql-connector-java-5.1.46.jar" />
	<context id="my" targetRuntime="MyBatis3">
		<commentGenerator>

		</commentGenerator>
		<!-- mysql数据库连接 -->
		<jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://1.1.1.1:3306/hahaha" userId="root" password="123456" />

		<!-- 生成model实体类文件位置 -->
		<javaModelGenerator targetPackage="com.wang.dao.dataobj" targetProject="src/main/java">
			<property name="enableSubPackages" value="true" />

		<!-- 需要生成的实体类对应的表名，多个实体类复制多份该配置即可 -->
		<table tableName="audio_chapter" domainObjectName="AudioChapterDO" enableCountByExample="true" enableUpdateByExample="true" enableDeleteByExample="true" enableSelectByExample="true" selectByExampleQueryId="true">
		</table>

	</context>
</generatorConfiguration>

然后在eclipse中run as maven build...输入goal：mybatis-generator:generate
