javaのSpringとMybatisについて調査した。（今年はPHPじゃないのをはじめた）
javaのSpringとMybatisについて調査した
１．mybatis-jpetstore-6.0.1-bundle.zip（http://code.google.com/p/mybatis/downloads/list?q=Product=Sample）のソースを流用（これ自体はWEBシステムのサンプルなので）してJAVAバッチを作った。
２．今回は動的SQLを使わなかったがここ（http://www.mybatis.org/core/ja/dynamic-sql.html）を参考にしてあとで試す。
３．pom.xmlを作るのにここ（http://brightgenerous.blogspot.jp/2012/01/spring3-mybatis3.html）を見本にした。
■eclipseでMavenのプロジェクトにした
■App.java(JAVAバッチ)のサンプル
package org.mybatis.jpetstore.app;
import java.util.List;
import org.mybatis.jpetstore.domain.Category;
import org.mybatis.jpetstore.domain.Signon2;
import org.mybatis.jpetstore.service.CatalogService;
import org.mybatis.jpetstore.service.Signon2Service;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class App {
private static ApplicationContext context;
/**
* @param args
*/
public static void main(String[] args) {
System.out.println("start");
context = new ClassPathXmlApplicationContext("applicationContext.xml");
CatalogService catalogService = context.getBean(CatalogService.class);
Category category = catalogService.getCategory("FISH");
System.out.println("category=" + category.toString());
List<Category> list = catalogService.getCategoryList();
System.out.println("list=" + list);
System.out.println("------");
Signon2Service sigon2Service = context.getBean(Signon2Service.class);
Signon2 signon2 = sigon2Service.getSignon2("ACID");
System.out.println("sigon2=" + signon2.toString());
signon2 = sigon2Service.getSignon2("ACID","ACID");
System.out.println("sigon2=" + signon2.toString());
System.out.println("------");
Signon2 signon2a = new Signon2();
signon2a.setUserName("ACID");
signon2a.setPassWord("ACID");
signon2 = sigon2Service.getSignon2(signon2a);
System.out.println("sigon2=" + signon2.toString());

try {
sigon2Service.doAll();
} catch (Exception up) {
System.out.println("------");
System.out.println("---Exception---");
System.out.println("Exception==" + up.toString());
}
System.out.println("==after doAll========================");
System.out.println("////////");
signon2a = new Signon2();
signon2a.setUserName("ACID");
signon2a.setPassWord("ACID");
Signon2 signon2b = sigon2Service.getSignon2(signon2a);
if (signon2b != null) {
System.out.println("sigon2b=" + signon2b.toString());
} else {
System.out.println("------");
System.out.println("---sigon2b null---");
}
}
}■applicationContext.xml ←Springを使う為の基本となる構成ファイル

package org.mybatis.jpetstore.domain;

}

}
}■Signon2Dao.java ←Daoのサンプル。MapperなのだけどDaoという名前のほうが一般的なのでSignon2Dao.javaにした。「getSignon2ByUsername(String userName);」は直接@Selectアノテーションを使ってみた。
package org.mybatis.jpetstore.persistence;
import org.apache.ibatis.annotations.Select;
import org.mybatis.jpetstore.domain.Signon2;
public interface Signon2Dao {

"PASS_WORD FROM SIGNON2 " +
"WHERE USER_NAME = #{userName}")
Signon2 getSignon2ByUsername(String userName);
Signon2 getSignon2ByUsernameAndPassword(String userName, String passWord);
Signon2 getSignon2ByUsernameAndPassword2(Signon2 signon2);
void insertSignon2(Signon2 signon2);
void updateSignon2(Signon2 signon2);
}■Signon2Dao.xml ←Daoのサンプル。Mapper.xmlなのだけどDaoという名前のほうが一般的なのでSignon2Dao.xmlにした。
