不处于事务控制下
无论是否发生导常
都 不提交记录

-----------------------------------------------------------------------------------------------------------

处于事务控制下
发生导常
不提交记录
-----------------------------------------------------------------------------------------------------------

配置文件最好分开

<prop key="hibernate.show_sql">true</prop>
-----------------------------------------------------------------------------------------------------------
drop TABLE sampledb.orders;
CREATE TABLE sampledb.orders(
`ID` BIGINT NOT NULL,
`ORDER_NUMBER` VARCHAR(15),
`CUSTOMER_ID` BIGINT,
PRIMARY KEY(`ID`)
)
ENGINE = InnoDB;

drop TABLE `sampledb`.`customers`;
CREATE TABLE `sampledb`.`customers` (
`ID` BIGINT NOT NULL,
`NAME` VARCHAR(45),
PRIMARY KEY(`ID`)
)
ENGINE = InnoDB;


alter table sampledb.orders
add constraint constraint_constraint_fk
foreign key (CUSTOMER_ID)
references sampledb.customers(ID);

用BeanNameAutoProxyCreator测试事务异常
BeanNameAutoProxyCreator总结
配置文件分开
-----------------------------------------------------------------------------------------------------------

先添加Spring Capabilities
再添加Hibernate Capabilities


-----------------------------------------------------------------------------------------------------------


package service;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class ServiceFactory {
public static ApplicationContext ctx;
public static ApplicationContext getApplicationContext() {
if (ctx == null) {
ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
}
return ctx;
}
}

-----------------------------------------------------------------------------------------------------------

package service;
import db.Customers;
public interface CustomersService {
public void save(Customers c);
}

-----------------------------------------------------------------------------------------------------------

package service;
import javax.sql.DataSource;
import org.springframework.jdbc.datasource.DataSourceUtils;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.support.TransactionTemplate;
import db.Customers;
import db.CustomersDAO;
public class CustomersServiceImpl extends HibernateDaoSupport implements
CustomersService {
private TransactionTemplate transactionTemplate;
public void setTransactionManager(
PlatformTransactionManager transactionManager) {
this.transactionTemplate = new TransactionTemplate(transactionManager);
}
public void save(Customers c) {
CustomersDAO dao = (CustomersDAO) ServiceFactory
.getApplicationContext().getBean("CustomersDAO");
dao.save(c);
// 下面两行代码没有实际意义，仅仅为了引发数据库异常
//DataSource ds = null;
//DataSourceUtils.getConnection(ds);
}
}
-----------------------------------------------------------------------------------------------------------

package test;
import service.CustomersService;
import service.ServiceFactory;
import db.Customers;
public class Demo {
public static void main(String[] args) {
CustomersService service = (CustomersService) ServiceFactory
.getApplicationContext().getBean("CustomersServiceImpl");
Customers c = new Customers();
c.setId(1l);
c.setName("xiong");
service.save(c);
System.out.println("END");
}
}
