使用GeneratorConfig自动生成Java类和XML文件

1.新建generatorConfig.xml在src/resources下

<?xml version="1.0" encoding="UTF-8"?>  
<!DOCTYPE generatorConfiguration  
      PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"  
      "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
	<!-- 数据库驱动 -->
	<classPathEntry location="C:\Users\d\.m2\repository\mysql\mysql-connector-java\5.1.36\mysql-connector-java-5.1.36.jar" />
	<context id="DB2Tables" targetRuntime="MyBatis3">
		<commentGenerator>
			<property name="suppressDate" value="true" />
			<!-- 是否去除自动生成的注释 true：是 ： false:否 -->
			<property name="suppressAllComments" value="true" />
		</commentGenerator>
		<!--数据库链接URL，用户名、密码 -->
		<jdbcConnection driverClass="com.mysql.jdbc.Driver"
			connectionURL="jdbc:mysql://localhost/ming_data" userId="root" password="root">
		</jdbcConnection>
		<javaTypeResolver>
			<property name="forceBigDecimals" value="false" />
		</javaTypeResolver>
		<!-- 生成模型的包名和位置 -->
		<javaModelGenerator targetPackage="cn.ming.data.repository.model" targetProject="src/main/java">
			<property name="enableSubPackages" value="true" />
			<property name="trimStrings" value="true" />
		</javaModelGenerator>
		<!-- 生成映射文件的包名和位置 -->
		<sqlMapGenerator targetPackage="cn.ming.data.repository.model.mapper" targetProject="src/main/java">
			<property name="enableSubPackages" value="true" />
		</sqlMapGenerator>
		<!-- 生成DAO的包名和位置 -->
		<javaClientGenerator type="XMLMAPPER" targetPackage="cn.ming.data.repository.dao" targetProject="src/main/java">
			<property name="enableSubPackages" value="true" />
		</javaClientGenerator>
		<!-- 要生成哪些表 -->
		<table tableName="data_table" domainObjectName="DataTable"
			enableCountByExample="false" enableUpdateByExample="false"
			enableDeleteByExample="false" enableSelectByExample="false"
			selectByExampleQueryId="false"></table>
		<table tableName="data_column" domainObjectName="DataColumn"
			enableCountByExample="false" enableUpdateByExample="false"
			enableDeleteByExample="false" enableSelectByExample="false"
			selectByExampleQueryId="false"></table>
	</context>
</generatorConfiguration>

2.配置pom.xml

<build>
	<plugins>
		<plugin>
			<groupId>org.mybatis.generator</groupId>
			<artifactId>mybatis-generator-maven-plugin</artifactId>
			<version>1.3.2</version>
			<configuration>
				<verbose>true</verbose>
				<overwrite>true</overwrite>
			</configuration>
		</plugin>
	</plugins>
</build>

3.执行

mvn mybatis-generator:generate
