1、spring mvc配置异常事物回滚机制
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
......(省略)
</bean>
<!-- 事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<!-- 事务控制 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="save*" propagation="REQUIRED" rollback-for="Exception" />
<tx:method name="do*" propagation="REQUIRED" rollback-for="Exception" />
<tx:method name="insert*" propagation="REQUIRED" rollback-for="Exception" />
<tx:method name="add*" propagation="REQUIRED" rollback-for="Exception" />
<tx:method name="update*" propagation="REQUIRED" rollback-for="Exception" />
<tx:method name="edit*" propagation="REQUIRED" rollback-for="Exception" />
<tx:method name="remove*" propagation="REQUIRED" rollback-for="Exception" />
<tx:method name="delete*" propagation="REQUIRED" rollback-for="Exception" />
<tx:method name="get*" read-only="true" />
<tx:method name="select*" read-only="true" />
<tx:method name="find*" read-only="true" />
</tx:attributes>
</tx:advice>
2、在特殊情况下使用手动事物回滚，如下
注：手动事物回滚写法简单，但不符合spring提倡的无入侵性，并会使代码与spring框架的事物高度耦合。
TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
