Spring中的事务管理实例详解(3)

public BookStockException(String arg0, Throwable arg1, boolean arg2,
            boolean arg3) {
        super(arg0, arg1, arg2, arg3);
        // TODO Auto-generated constructor stub
    }

public BookStockException(String arg0, Throwable arg1) {
        super(arg0, arg1);
        // TODO Auto-generated constructor stub
    }

public BookStockException(String arg0) {
        super(arg0);
        // TODO Auto-generated constructor stub
    }

public BookStockException(Throwable arg0) {
        super(arg0);
        // TODO Auto-generated constructor stub
    }
}

UserAccountException

 码如下:

package com.yl.spring.tx;
public class UserAccountException extends RuntimeException {

/**
    *
    */
    private static final long serialVersionUID = 1L;

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

代码如下:

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

代码如下:

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：

代码如下:

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"));
    }
