SpringFrameworkでMyBatisを使ってみる(Javaアプリケーション)③
今回は、MyBatis GeneratorというDBアクセス関連のファイルを自動生成してくれるツールを使ってみます。このツールはMyBatisの公式ページ(http://www.mybatis.org/generator/ )で公開されています。
ダウンロード
公式ページよりリンクを辿り、Zipファイルをダウンロードし、適当なフォルダに解凍します。http://blog.mybatis.org/p/products.html
上記のリンクをクリックすると以下の画面に遷移します。
https://github.com/mybatis/generator/releases
上記、Zipファイルをダウンロードし、適当なフォルダに解凍します。
設定ファイルの作成
接続先DBや対象テーブルなどを指定する設定ファイルを作成します。
<?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="C:\Program Files (x86)\PostgreSQL\pgJDBC\postgresql-9.4.1208.jar"/>
<context id="PostgresTables" targetRuntime="MyBatis3">
<jdbcConnection driverClass="org.postgresql.Driver"
connectionURL="jdbc:postgresql://localhost:5432/postgres"
userId="postgres"
password="ps" />
<javaModelGenerator targetPackage="spring.test"
targetProject="C:\workspace\springApp\src" />
<sqlMapGenerator targetPackage="spring.test"
targetProject="C:\workspace\springApp\src" />
<javaClientGenerator targetPackage="spring.test"
targetProject="C:\workspace\springApp\src" type="XMLMAPPER" />
<table tableName="m_user" />
</context>
</generatorConfiguration>
今回は以下のテーブルより自動生成してみます。
create table public.m_user (
id character varying(8) not null
, name character varying(16)
, primary key (id)
);
自動生成ファイルの生成
Javaアプリケーションとして実行できます。
cd C:\work\hp\mybatis-generator-core-1.3.3
java -cp lib/mybatis-generator-core-1.3.3.jar org.mybatis.generator.api.ShellRunner -configfile generatorConfig.xml
↑画面表示が切れて行末まで見れない場合、以下となっています
java -cp lib/mybatis-generator-core-1.3.3.jar (改行)
org.mybatis.generator.api.ShellRunner (改行)
-configfile generatorConfig.xml
上記以外にも、Ant、Maven、Eclipseのプラグインなど様々な方法で実行することができますので、 興味があれば、公式ページなどで確認してください。
作成ファイル
上記までの操作で自動生成されたファイルは以下になります。SQL設定ファイル(MUserMapper.xml)
モデル(MUser.java)
条件クラス(MUserExample.java)
マッパークラス(MUserMapper.java)
SQL設定ファイル(MUserMapper.xml)
