Spring事务配置

tx头配置文件(必须写):
 <beans xmlns="http://www.springframework.org/schema/beans" 
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
         xmlns:aop="http://www.springframework.org/schema/aop" 
         xmlns:tx="http://www.springframework.org/schema/tx" 
        xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.0.xsd 
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-2.0.xsd 
           http://www.springframework.org/schema/tx
           http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"> 


<!-- 声明式事务 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager" >transaction-manager默认就是transactionManager，假如你的事务ID为transactionManager的话，那写不写都无所谓
    <tx:attributes>
        <tx:method name="add*" propagation="REQUIRED"/>   
        <tx:method name="insert*" propagation="REQUIRED"/>
        <tx:method name="delete*" propagation="REQUIRED"/>
        <tx:method name="update*" propagation="REQUIRED"/>
        <tx:method name="test*" propagation="REQUIRED" rollback-for="Exception"/>结果不写 rollback-for它弄死都不给你回滚，这个东西弄了半天
        <tx:method name="*" propagation="REQUIRED" read-only="true"/>
    </tx:attributes>
</tx:advice>
<aop:config proxy-target-class="true">proxy-target-class默认是false，不写有可能给你报个错,报错信息blog最后写
    <aop:advisor advice-ref="txAdvice" pointcut="execution(* *..TestUserServiceTransManager.*(..))"/>
execution(* *..TestUserServiceTransManager.*(..))实现了TestUserServiceTransManager借口的所有bean,我也不晓得哪些*是怎么写的，照书炒的
execution(* com.my.service.*.*(..))
第一个*:返回类型
第二个*:com.my.service下的class类
第三个*:com.my.service下的class类的方法
(..):传递的参数
</aop:config>


<!-- 注解事务 -->
<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/>
proxy-target-class和上面aop的proxy-target-class一样的，不写可能会报错
@Transactional(propagation=Propagation.REQUIRED,rollbackFor=Exception.class)
propagation=Propagation.REQUIRED可写可不写默认就这样
rollbackFor和上面rollback-for一样的，不写打死不给你回滚

今天郁闷的很，报错报安逸了，就少了2个包,分别是:cglib-2.1.3.jar,asm.jar
报错信息:
org.springframework.beans.factory.BeanCreationException
asm.jar:
nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'testUserServiceTransManager' defined in ServletContext resource [/WEB-INF/classes/config/spring/spring_service_test.xml]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class net.sf.cglib.core.KeyFactory

cglib-2.1.3.jar:
nested exception is org.springframework.aop.framework.AopConfigException: Cannot proxy target class because CGLIB2 is not available. Add CGLIB to the class path or specify proxy interfaces.

不写proxy-target-class:
nested exception is java.lang.IllegalStateException: Cannot convert value of type [$Proxy4 implementing com.sjth.service.TestUserServiceTransManager,org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised] to required type [com.sjth.service.impl.TestUserServiceTransManageerImpl] for property 'testUserServiceTransManager': no matching editors or conversion strategy found
