步骤 1 :

删除Product表所有数据

edit
为了观察事务现象,需要对数据做一些准备,首先把product_ 表里的数据都删除
delete from product_
delete from product_
步骤 2 :

先运行,看到效果,再测试

edit
访问地址:

http://127.0.0.1:8080/ssh/listProduct

会看到如图所示的异常(这是故意造成的)。
接着执行sql语句

select * from product_

会发现表里没有数据,即表明相关操作在事务里,当发生异常后,数据并没有被提交
先运行,看到效果,再测试
事务概念,表现在4个方面:
原子性(Atomicity),一致性(Consistency),隔离性(Isolation),持续性/永久性(Durability)
大家接触的最直接的是原子性,即要么都成功,要么都失败。

本知识点,在整合步骤的基础上进行,当数据库中没有产品的时候,会新创建5个产品。那么所谓的原子性就是,要么5个产品都创建成功,要么一个也别创建。
List<Product> products= productDAO.list(); if(products.isEmpty()){ for (int i = 0; i < 5; i++) { Product p = new Product(); p.setName("product " + i); productDAO.add(p); products.add(p); } }
        List<Product> products= productDAO.list();
        if(products.isEmpty()){
            for (int i = 0; i < 5; i++) {
                Product p = new Product();
                p.setName("product " + i);
                productDAO.add(p);
                products.add(p);
            }
        }
步骤 4 :

故意制造异常,观察无事务管理的结果

edit
在默认情况下是没有进行事务管理的,所以故意把代码修改,制造错误:
当i==2的时候,抛出一个运行时异常,这样,就只创建了2条,而不是本来计划5条数据。
修改后,清空product_表,重启tomcat,运行
1. 第一次运行会抛出异常
2. 第二次运行,因为已经有数据了,所以不会抛异常,但是只会看到2条数据。

这就是没有事务管理的后果,只有部分数据增加
故意制造异常,观察无事务管理的结果
package com.how2java.service.impl; import java.util.List; import org.springframework.orm.hibernate3.HibernateTemplate; import com.how2java.dao.ProductDAO; import com.how2java.pojo.Product; import com.how2java.service.ProductService; public class ProductServiceImpl implements ProductService { ProductDAO productDAO; public List<Product> list() { List<Product> products= productDAO.list(); if(products.isEmpty()){ for (int i = 0; i < 5; i++) { if(i==2) throw new RuntimeException(); Product p = new Product(); p.setName("product " + i); productDAO.add(p); products.add(p); } } return products; } public ProductDAO getProductDAO() { return productDAO; } public void setProductDAO(ProductDAO productDAO) { this.productDAO = productDAO; } }
步骤 5 :

配置事务管理

edit
SSH的配置事务管理是非侵入式的,所谓的非侵入式,就是指不需要修改一行java代码,只需要进行applicationContext.xml的配置,即可达到事务管理的效果。
1. 增加一个专门进行事务管理的bean

<tx:advice id="txadvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="add*" propagation="REQUIRED" rollback-for="Exception" />
<tx:method name="del*" propagation="REQUIRED" rollback-for="Exception"/>
<tx:method name="edit*" propagation="REQUIRED" rollback-for="Exception" />
<tx:method name="update*" propagation="REQUIRED" rollback-for="Exception"/>
<tx:method name="list*" propagation="REQUIRED" rollback-for="Exception"/>
</tx:attributes>
</tx:advice>

这里面的add*,del*等等,表示对于这些名词开头的方法,进行事务管理。
2. 配置切面

<aop:config>
<aop:pointcut id="serviceMethod" expression="execution(* com.how2java.service.*.*(..))"/>
<aop:advisor pointcut-ref="serviceMethod" advice-ref="txadvice"/>
</aop:config>

这里使用了AOP切面编程的配置手段,让前面配置的事务管理bean,去和业务方法编织在一起。
哪些业务方法呢?

execution(* com.how2java.service.*.*(..))

* 返回任意类型
com.how2java.service.* 包名以com.how2java.service 开头的类的任意方法
(..) 任意的参数类型
这样就达到了对ProductServiceImpl的list()方法,进行事务管理的效果

步骤 6 :

观察有事务管理的结果

edit
同样的,先删除掉product_里的所有数据,然后访问页面

http://127.0.0.1:8080/ssh/listProduct

就会观察到,无论访问多少次,都会抛出异常,并且数据库里的数据,一直都为空。
为什么呢?作为一个事务里的方法,当i==2的时候,抛出异常,这个事务就回滚了,在i==0,i==1的时候插入到数据库里的两条数据,也就回滚了。
从而达到了,要么一次性插入5条数据,要么一条也别插入的效果。
观察有事务管理的结果
步骤 7 :

Spring事务类型详解

edit
配置事务管理中有这么一行配置信息:

<tx:method name="add*" propagation="REQUIRED" rollback-for="Exception" />

这个REQUIRED,就是Spring事务类型,除了这种,还有其他好几种,都列罗在下:
REQUIRED--支持当前事务,如果当前没有事务,就新建一个事务。这是最常见的选择。
SUPPORTS--支持当前事务,如果当前没有事务,就以非事务方式执行。
MANDATORY--支持当前事务,如果当前没有事务,就抛出异常。
REQUIRES_NEW--新建事务,如果当前存在事务,把当前事务挂起。
NOT_SUPPORTED--以非事务方式执行操作,如果当前存在事务,就把当前事务挂起。
NEVER--以非事务方式执行,如果当前存在事务,则抛出异常。
NESTED--如果当前存在事务,则在嵌套事务内执行。如果当前没有事务,则进行与REQUIRED类似的操作。

最常见的就第一种REQUIRED,其他的,我也没怎么用过 -_-~
步骤 8 :

MYSQL 表的类型必须是INNODB才支持事务

edit
在Mysql中,只有当表的类型是INNODB的时候,才支持事务,所以需要把表的类型设置为INNODB,否则无法观察到事务.

修改表的类型为INNODB的SQL:

alter table product_ ENGINE = innodb;


查看表的类型的SQL

show table status from how2java;


不过有个前提,就是当前的MYSQL服务器本身要支持INNODB,如果不支持,请看 开启MYSQL INNODB的办法

可以在DAO的spring配置中加上 <property name="checkWriteOperations" value="false" /> 就可以进行写操作了;
<bean name="productDAOImpl" class="DAO.ProductDAOImpl">
        <property name="sessionFactory" ref="sf" />
        <property name="checkWriteOperations" value="false" />
</bean>

这个问题我也遇到了,配置事务管理后就解决。这个是dao层抛出的异常哈

2017-09-04 关于切点
冇杀我啊

execution(* com.how2java.service.*.*(..)) 怎么达到了对ProductServiceImpl的list()方法,进行事务管理的效果 不是应该修改成execution(* com.how2java.service.impl.*.*(..)) 吗?

包含子包应该是execution(* com.how2java.service..*.*(..)) service后面两个.. 站长这里实际上是对接口方法定义了切点导致事物生效。

老师你好,请问execution(* com.how2java.service.*.*(..)) 和execution(* com.how2java.service.*(..)) 有啥区别?之前在AOP切面编程老师你写的是第二种写法,愚生不解,望赐教。

execution(* com.how2java.service.*.*(..)) 包含了子包呢: execution(* com.how2java.service.impl.*.*(..))
