Spring中的事务管理实例详解(5)
public UserAccountException() {
super();
// TODO Auto-generated constructor stub
}
public UserAccountException(String arg0, Throwable arg1, boolean arg2,
boolean arg3) {
super(arg0, arg1, arg2, arg3);
// TODO Auto-generated constructor stub
}
public UserAccountException(String arg0, Throwable arg1) {
super(arg0, arg1);
// TODO Auto-generated constructor stub
}
public UserAccountException(String arg0) {
super(arg0);
// TODO Auto-generated constructor stub
}
public UserAccountException(Throwable arg0) {
super(arg0);
// TODO Auto-generated constructor stub
}
}
Cashier
package com.yl.spring.tx;
import java.util.List;
public interface Cashier {
public void checkout(String username, List<String>isbns);
}
CashierImpl。CashierImpl.checkout和bookShopService.purchase联合测试了事务的传播行为
package com.yl.spring.tx;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
@Service("cashier")
public class CashierImpl implements Cashier {
@Autowired
private BookShopService bookShopService;
@Transactional
@Override
public void checkout(String username, List<String> isbns) {
for(String isbn : isbns) {
bookShopService.purchase(username, isbn);
}
}
}
测试类：
package com.yl.spring.tx;
import java.util.Arrays;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class SpringTransitionTest {
private ApplicationContext ctx = null;
private BookShopDao bookShopDao = null;
private BookShopService bookShopService = null;
private Cashier cashier = null;
{
ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
bookShopDao = ctx.getBean(BookShopDao.class);
bookShopService = ctx.getBean(BookShopService.class);
cashier = ctx.getBean(Cashier.class);
}
@Test
public void testBookShopDaoFindPriceByIsbn() {
System.out.println(bookShopDao.findBookPriceByIsbn("1001"));
}
