在myeclipse中示例

一：ibatis自动生成代码

安装下面的插件：http://ibatis.apache.org/tools/abator

配置文件如下：abatorConfig.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE abatorConfiguration PUBLIC "-//Apache Software Foundation//DTD Abator for iBATIS Configuration 1.0//EN" "http://ibatis.apache.org/dtd/abator-config_1_0.dtd" >
<abatorConfiguration ><abatorContext ><!--  数据库连接的信息：驱动类、连接地址、用户名、密码--><jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver" connectionURL="jdbc:oracle:thin:@192.168.4.136:1521:sgmparts" userId="flycartest" password="flycartest" ><!--classPathEntry 数据库的JDBC驱动的jar包地址--><classPathEntry location="E:\MyWorkSpace\flycar-parent\web-demo\lib\ojdbc6.jar" /></jdbcConnection><!--生成java实体类对应的项目以及所在的包--><javaModelGenerator targetPackage="test.model" targetProject="web-demo" /><!--生成mapper.xml对应的项目以及所在的包--><sqlMapGenerator targetPackage="test.mapper" targetProject="web-demo" /><!--生成dao层java类对应的项目以及所在的包--><daoGenerator targetPackage="test.dao" targetProject="web-demo" type="GENERIC-CI" /><!--数据相关表配置,schema即为数据库名,tableName为表名,domainObjectName是要生成的实体类--><table schema="" tableName="Student" domainObjectName="Student">    </table></abatorContext>
</abatorConfiguration>

然后右键单击选择

这样就OK了，自动生成了相关代码

二：mybatis自动生成代码

首先配置maven插件：pom.xml

       <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>

然后是配置文件：generatorConfig.xml

<?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="E:\MyWorkSpace\flycar-parent\web-demo\lib\ojdbc6.jar" />  --><!-- classPathEntry:数据库的JDBC驱动的jar包地址--> <classPathEntry location="E:\MyWorkSpace\mysql-connector-java-5.1.6-bin.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>  <!--数据库连接的信息：驱动类、连接地址、用户名、密码 --> <jdbcConnection driverClass="com.mysql.jdbc.Driver"  connectionURL="jdbc:mysql://127.0.0.1:3306/develop" userId="develop" password="develop">  </jdbcConnection>  <javaTypeResolver>  <property name="forceBigDecimals" value="false" />  </javaTypeResolver>  <javaModelGenerator targetPackage="com.raxtone.flycar.admin.entity"  targetProject="E:\MyWorkSpace\flycar-parent\web-demo\src\main\java"> <!-- enableSubPackages:是否让schema作为包的后缀 -->       <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>  <sqlMapGenerator targetPackage="com.raxtone.flycar.admin.mapper"  targetProject="E:\MyWorkSpace\flycar-parent\web-demo\src\main\java"><!-- enableSubPackages:是否让schema作为包的后缀 -->   <property name="enableSubPackages" value="false" />  </sqlMapGenerator>  <javaClientGenerator type="XMLMAPPER"  targetPackage="com.raxtone.flycar.admin.mapper" targetProject="E:\MyWorkSpace\flycar-parent\web-demo\src\main\java">  <!-- enableSubPackages:是否让schema作为包的后缀 --> <property name="enableSubPackages" value="true" />  </javaClientGenerator>  <!-- tableName:用于自动生成代码的数据库表；domainObjectName:对应于数据库表的javaBean类名 --><!--  schema即为数据库名, tableName为对应的数据库表, domainObjectName是要生成的实体类,如果想要mapper配置文件加入sql的where条件查询, 可以将enableCountByExample等设为true,这样就会生成一个对应domainObjectName的Example类, enableCountByExample等设为false时,就不会生成对应的Example类了. --><table tableName="t_apply_person" domainObjectName="ApplyPerson" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" >  </table>  </context>  
</generatorConfiguration> 

然后执行下图操作

mybatis-generator:generate
