mybatis利用maven插件自动生成代码

第一种方式:

配置maven插件:

<plugin>
	   <groupId>org.mybatis.generator</groupId>
	   <artifactId>mybatis-generator-maven-plugin</artifactId>
	   <version>1.3.0</version>
	   <dependencies>
		   <dependency>
			  <groupId>mysql</groupId>
			  <artifactId>mysql-connector-java</artifactId>
			  <version>5.1.34</version>
		   </dependency>
	   </dependencies>
	   <configuration>
			 <overwrite>true</overwrite>
	   </configuration>
</plugin>

在src/main/resources下新建generatorConfig.xml 内容如下：

<?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>
	<context id="mysqlgenerator" targetRuntime="MyBatis3">
		<jdbcConnection driverClass="com.mysql.jdbc.Driver"
		                connectionURL="jdbc:mysql://10.230.10.27:3306/gw2_dianquan?useUnicode=true&amp;characterEncoding=UTF-8" 
		                userId="hongdian"
		                password="123456"/>
		<javaModelGenerator targetPackage="com.kongzhong.gw2.onepercentbg.domain" targetProject="src\main\java" />
		<sqlMapGenerator targetPackage="com.kongzhong.gw2.onepercentbg.mapper" targetProject="src\main\resources" />
		<javaClientGenerator type="XMLMAPPER" targetPackage="com.kongzhong.gw2.onepercentbg.mapper" targetProject="src\main\java" />
		<table tableName="t_yizhestore_item" domainObjectName="Items"/>
	</context> 
</generatorConfiguration>

maven命令：

mybatis-generator:generate

第二种方式:

配置maven插件:

<plugin>
    <groupId>org.mybatis.generator</groupId>
	<artifactId>mybatis-generator-maven-plugin</artifactId>
	<version>1.3.2</version>
	<configuration>
	     <overwrite>true</overwrite>
		 <verbose>true</verbose>
	</configuration>
	<dependencies>
	      <!--数据库驱动-->
		  <dependency>
		      <groupId>mysql</groupId>
			  <artifactId>mysql-connector-java</artifactId>
			  <version>5.1.34</version>
		  </dependency>
	</dependencies>
</plugin>

在src/main/resources下新建generatorConfig.xml 内容如下：

<?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> 
	<context id="sqlserverTables" targetRuntime="MyBatis3"> 
		<!-- 生成的pojo，将implements Serializable--> 
		<plugin type="org.mybatis.generator.plugins.SerializablePlugin"></plugin> 
		<commentGenerator> 
			<!-- 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://127.0.0.1:3306/thinkphp?useUnicode=true&amp;characterEncoding=UTF-8" 
		                userId="root" 
		                password="root"> 
		</jdbcConnection> 

		<!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer 
		true，把JDBC DECIMAL 和 NUMERIC 类型解析为java.math.BigDecimal 
		--> 
		<javaTypeResolver> 
		       <property name="forceBigDecimals" value="false" /> 
		</javaTypeResolver> 

		<!-- 生成model模型，对应的包路径，以及文件存放路径(targetProject)，targetProject可以指定具体的路径,如./src/main/java， 
		也可以使用“MAVEN”来自动生成，这样生成的代码会在target/generatord-source目录下 
		--> 
		<!--<javaModelGenerator targetPackage="com.joey.mybaties.test.pojo" targetProject="MAVEN">--> 
		<javaModelGenerator targetPackage="com.kongzhong.gw2.ccc.mapper" targetProject="./src/main/java"> 
			<property name="enableSubPackages" value="true"/> 
			<!-- 从数据库返回的值被清理前后的空格 --> 
			<property name="trimStrings" value="true" /> 
		</javaModelGenerator> 

		<!--对应的mapper.xml文件 --> 
		<sqlMapGenerator targetPackage="com.kongzhong.gw2.ccc.mapper" targetProject="./src/main/resources"> 
		       <property name="enableSubPackages" value="true"/> 
		</sqlMapGenerator> 

		<!-- 对应的Mapper接口类文件 --> 
		<javaClientGenerator type="XMLMAPPER" targetPackage="com.kongzhong.gw2.ccc.mapper" targetProject="./src/main/java"> 
		      <property name="enableSubPackages" value="true"/> 
		</javaClientGenerator> 


		<!-- 列出要生成代码的所有表，这里配置的是不生成Example文件 --> 
		<table tableName="tp_user" domainObjectName="User" 
		       enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" 
		       enableSelectByExample="false" selectByExampleQueryId="false" > 
		       <property name="useActualColumnNames" value="false"/> 
		</table> 

	</context> 
</generatorConfiguration>

执行maven命令

mybatis-generator:generate
