스프링,아이바티스트랜잭션예제[Spring Framework3.X,Transaction,iBATIS, @Transactional]

스프링,아이바티스트랜잭션예제[Spring Framework3.X,Transaction,iBATIS, @Transactional]
 
스프링의 트랜잭션 관리 방법중 @Transactional 애노테이션을 이용하여 iBATIS와 연동하는 간단 예제이다.(오라클 emp 테이블에 Data 1건 insert..)

먼저 Spring MVC 프로젝트 하나 생성하자.

2. 컨트롤러
 
package onj.edu.transaction;
import java.util.Locale;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class HomeController {
 @Autowired
 private TransactionMain transactionMain;

 @RequestMapping(value = "/hello", method = RequestMethod.GET)
 public String home(Locale locale, Model model) {
  String msg = "";
  try {
   msg = transactionMain.insert();
  } catch (Throwable e) {
   msg = "Transaction 오류";
   e.printStackTrace();
  }
  model.addAttribute("msg", msg );
  return "onj";
 }
}
 
3. 트랜잭션 메인 클래스
 
package onj.edu.transaction;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
public class TransactionMain {
 @Autowired
 private Tran1 tr1;

 @Transactional(propagation = Propagation.REQUIRED)
 public String insert() throws Throwable {
  tr1.insertTest();
 
  return "Transaction Success!!";
 }
}

4. 트랜잭션 처리 클래스(간단히 EMP 테이블에 한건 인서트)

package onj.edu.transaction;
import java.util.HashMap;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.ibatis.SqlMapClientTemplate;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
public class Tran1 {
 @Autowired
 private SqlMapClientTemplate sqlMapClientTemplate;

 @Transactional(propagation = Propagation.REQUIRED)
 public void insertTest() {
  HashMap<String, String> hashMap = new HashMap<String, String>();
  hashMap.put("empno", "101");
  hashMap.put("ename", "오엔제이");
  sqlMapClientTemplate.insert("sql.empinsert1", hashMap);
 }
}
