使用MyBatis Generator自动生成代码

参考：MyBatis Generator API
http://generator.sturgeon.mopaas.com/
1、新建MAVEN项目
2、pom.xml中添加generator的依赖
<dependency>
<groupId>org.mybatis.generator</groupId>  
<artifactId>mybatis-generator-core</artifactId>  
<version>1.3.2</version>  
</dependency>
...
...
...
<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>
<dependencies>
<dependency>
<groupId>mygroup</groupId>
<artifactId>myproject</artifactId>
<version>${version}</version>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>

3、配置
<?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>
<classPathEntry location="D:/Maven/repo/mysql/mysql-connector-java/5.1.30/mysql-connector-java-5.1.30.jar" />
<context id="DB2Tables" targetRuntime="MyBatis3" defaultModelType="flat">
<property name="autoDelimitKeywords" value="true"/>
<property name="beginningDelimiter" value="`"/>
<property name="endingDelimiter" value="`"/>
<plugin type="org.mybatis.generator.plugins.EqualsHashCodePlugin" />
<plugin type="org.mybatis.generator.plugins.RowBoundsPlugin"></plugin>
<commentGenerator>
<property name="suppressAllComments" value="true"/>
<property name="suppressDate" value="true" />
</commentGenerator>
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/kv_pz?useUnicode=true"
userId="root" password="">
</jdbcConnection>
<javaTypeResolver>
<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>
<javaModelGenerator targetPackage="com.mybatis.model" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
<property name="trimStrings" value="true"/>
<property name="rootClass" value="com.mybatis.model.Entity"/>
</javaModelGenerator>
<sqlMapGenerator targetPackage="sqlmap" targetProject="src/main/resources">
<property name="enableSubPackages" value="true"/>
</sqlMapGenerator>
<javaClientGenerator type="XMLMAPPER" targetPackage="com.mybatis.dao" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
<property name="rootInterface" value="com.mybatis.dao.BaseDao"/>
</javaClientGenerator>
<table tableName="config" domainObjectName="Config">
<generatedKey column="id" sqlStatement="MySql" identity="true"/>
</table>
</context>
</generatorConfiguration>

4、代码生成
run as => maven build => 在弹出框中的goals处输入mybatis-generator:generate => OK
代码自动生成了
如果重复生成，mapper文件中的内容是不会被覆盖的，而是在最后面进行追加，所以如果连续生成两次，mapper文件就会出错，所以在生成前最好将原来生成的文件全部删除
