SPRING注解事务失效处理汇总
情况1:
在声明式事务和注解事务并存的情况下会出现注解事务失效的问题
处理方法如下:
方法1:

<aop:config><aop:pointcut id="transactionOperation"expression="execution(* com.comtop..*.facade.*.*(..))" /><aop:advisor advice-ref="txAdvice" pointcut-ref="transactionOperation" order="1"/></aop:config>

在配置中加上参数order="1" 设置时序 order越小 顺序越靠前

方法2:

 <tx:advice id="txAdvice" transaction-manager="transactionManager"><tx:attributes><tx:method name="get*" read-only="true"/><tx:method name="query*" read-only="true"/><tx:method name="*NoJTA" read-only="true"/><tx:method name="*" /></tx:attributes></tx:advice><aop:config><aop:pointcut id="transactionOperation"expression="execution(* com.comtop..*.facade.*.*(..))" /><aop:advisor advice-ref="txAdvice" pointcut-ref="transactionOperation" order="1"/></aop:config><tx:annotation-driven proxy-target-transaction-manager="transactionManager" />

将<tx:annotation-driven proxy-target-transaction-manager="transactionManager" />放在<aop:config>和<tx:advice>后面

情况2:
实例化@Controller类时，Spring会自动把关联的@Service（此@Service已做了@Transaction事务注解）类实例化，此时事务并未生效，导致@Transaction注解无效，事务未被注册
解决方法:

<context:component-scan base-package="com.comtop"  use-default-filters="false" >        <context:include-filter expression="org.springframework.stereotype.Controller" type="annotation"/> </context:component-scan> <context:component-scan base-package="com.comtop">         <context:exclude-filter expression="org.springframework.stereotype.Controller" type="annotation"/> </context:component-scan> 

use-default-filters="false" 的意思是不实例化关联到的servcie context:include和context:exclude分别是包含和屏蔽
