mybatis-generatorで使用し、ideaでマッピングプロファイル、daoインタフェース、エンティティクラスを自動的に生成します.

プロセス
##1.依存関係の導入

        <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.6</version>
        </dependency>

##2.プロファイルmybatis-generatorconfig.xml
公式ドキュメントのリンクによると:mybatis-generator.

<?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="DB2Tables" targetRuntime="MyBatis3">
        <!--         ，   DefaultCommentGenerator         -->
    <commentGenerator>
    <property name="suppressAllComments" value="true"/>
</commentGenerator>
    <!--       -->
  <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>
    <!--  javabean     -->
    <javaModelGenerator targetPackage="test.model" targetProject="\MBGTestProject\src">
      <property name="enableSubPackages" value="true" />
      <property name="trimStrings" value="true" />
    </javaModelGenerator>
 <!--  sql        -->
    <sqlMapGenerator targetPackage="test.xml"  targetProject="\MBGTestProject\src">
      <property name="enableSubPackages" value="true" />
    </sqlMapGenerator>
  <!--  dao        mapper  -->
    <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>

##3.テストクラス作成実行生成

   public class Generator {
    public static void main(String[] args) throws Exception {
        List<String> warnings = new ArrayList<String>();
        boolean overwrite = true;
        File configFile = new File("mybatis-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);
    }
}
