Mybatis的逆向工程（generator）。由表帮我们生成dao，bean，xml映射文件。
在http://www.mybatis.org/generator/index.html上可以找到我们所需要的资料。
具体操作流程如下：
1.在该网页中选择快速入门
2.引入mybatis-generator的jar包
3.设置xml配置文件
复制点击此链接之后的代码
<?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="/Program Files/IBM/SQLLIB/java/db2java.zip" /> <context id="DB2Tables" targetRuntime="MyBatis3"> <jdbcConnection driverClass="COM.ibm.db2.jdbc.app.DB2Driver" connectionURL="jdbc:db2:TEST" userId="db2admin" password="db2admin"> </jdbcConnection> <javaTypeResolver > <property name="forceBigDecimals" value="false" /> </javaTypeResolver> <javaModelGenerator targetPackage="test.model" targetProject="\MBGTestProject\src"> <property name="enableSubPackages" value="true" /> <property name="trimStrings" value="true" /> </javaModelGenerator> <sqlMapGenerator targetPackage="test.xml" targetProject="\MBGTestProject\src"> <property name="enableSubPackages" value="true" /> </sqlMapGenerator> <javaClientGenerator type="XMLMAPPER" targetPackage="test.dao" targetProject="\MBGTestProject\src"> <property name="enableSubPackages" value="true" /> </javaClientGenerator> <table schema="DB2ADMIN" tableName="ALLTYPES" domainObjectName="Customer" > <property name="useActualColumnNames" value="true"/> <generatedKey column="ID" sqlStatement="DB2" identity="true" /> <columnOverride column="DATE_FIELD" property="startDate" /> <ignoreColumn column="FRED" /> <columnOverride column="LONG_VARCHAR_FIELD" jdbcType="VARCHAR" /> </table> </context> </generatorConfiguration>
在自己的工程中需要对源码进行修改
4.运行generator文件
将此链接中的代码复制到新建的TestGRT.java中
List<String> warnings = new ArrayList<String>();
boolean overwrite = true;
File configFile = new File("generatorConfig.xml");
ConfigurationParser cp = new ConfigurationParser(warnings);
Configuration config = cp.parseConfiguration(configFile);
DefaultShellCallback callback = new DefaultShellCallback(overwrite);
MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
myBatisGenerator.generate(null);
然后开始导包（导包快捷键CTRL+shift+o）
刷新工程，可以看见生成的bean包，dao包和mapper包。
