事务配置

切点 pointcut

下面给出一些常见切入点表达式的例子：
任意公共方法的执行：
execution(public * *(..))
任何一个以“set”开始的方法的执行：
execution(* set*(..))
AccountService 接口的任意方法的执行：
execution(* com.xyz.service.AccountService.*(..))
定义在service包里的任意方法的执行：
execution(* com.xyz.service.*.*(..))
定义在service包或者子包里的任意类的任意方法的执行：
execution(* com.xyz.service..*.*(..))

事务隔离级别
一、Propagation（事务的传播属性）, key属性确定代理应该给哪个方法增加事务行为。这样的属性最重要的部份是传播行为。有以下选项可供使用：
Enumerated Values :
- 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

Isolation (事务隔离等级): 属性一共支持五种事务设置，具体介绍如下：
Enumerated Values :
- DEFAULT 使用数据库设置的隔离级别 ( 默认 ) ，由 DBA 默认的设置来决定隔离级别 .
- READ_UNCOMMITTED 会出现脏读、不可重复读、幻读 ( 隔离级别最低，并发性能高 )
- READ_COMMITTED 会出现不可重复读、幻读问题（锁定正在读取的行）
- REPEATABLE_READ 会出幻读（锁定所读取的所有行）
- SERIALIZABLE 保证所有的情况不会发生（锁表）

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<aop:config> 
<aop:pointcut id="pointcut" expression="execution(public * com.microcloud.mcc.service.impl..*.*(..))" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="pointcut" />
</aop:config>
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="add*" propagation="REQUIRED" />
<tx:method name="insert*" propagation="REQUIRED" />
<tx:method name="del*" propagation="REQUIRED" />
<tx:method name="modify*" propagation="REQUIRED" />
<tx:method name="update*" propagation="REQUIRED" />
<tx:method name="save*" propagation="REQUIRED" />
<tx:method name="import*" propagation="REQUIRED" />
<tx:method name="*" propagation="REQUIRED" read-only="true" />
</tx:attributes>
</tx:advice>

<aop:aspectj-autoproxy proxy-target-class="true" />

资源文件配置
<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basenames">
<list>
<value>resources.localization_zh_CN</value>
</list>
</property>
<property name="useCodeAsDefaultMessage" value="true" />
</bean>

<bean id="demoTask" class="com.DemoTask"/>
