声明注解式事务
参考错误解决:
终于找到全annotation配置springMVC的方法了（事务不失效): http://icanfly.iteye.com/blog/778401
解决 spring mvc 3.0 结合 hibernate3.2 使用<tx:annotation-driven>声明式事务无法提交的问题:

留言下面写到:mvc 的只扫描controller组件 注意使用 use-default-filters="false"
<context:component-scan base-package="com.fengzhiyin" use-default-filters="false" >
<context:include-filter expression="org.springframework.stereotype.Controller" type="annotation"/>
</context:component-scan>

主体的扫描除controller外的所有组件
<context:component-scan base-package="com.fengzhiyin" >
<context:exclude-filter expression="org.springframework.stereotype.Controller" type="annotation"/>
</context:component-scan>

产生问题:
java.lang.NoClassDefFoundError: org/objectweb/asm/Type:

java.lang.NoSuchMethodError: org.objectweb.asm.org.objectweb.asm.ClassWriter.:

同时，抛出异常应该是RuntimeException类型的异常，否则事务失败。
throw new RuntimeException("@@@@@@@@@@@@@@@@@@ RollBack...............");


配置原则:
spring-servlet.xml只负责扫描controller类。
applicationContext.负责扫描controller以外的类。
因为spring的context是父子容器，所以会产生冲突，Controller会先进行扫描装配，而此时的Service还没有进行事务的增强处理，得到的将是原样的Service（没有经过事务加强处理，故而没有事务处理能力） ，最后才是applicationContext.xml中的扫描配置进行事务处理。
xml被扫描顺序参考： http://sence-qi.iteye.com/blog/1328902
由于服务器启动时的加载配置文件的顺序为web.xml---root-context.xml(Spring的配置文件)---servlet-context.xml(SpringMVC的配置文件)，由于root-context.xml配置文件中Controller会先进行扫描装配，但是此时service还没有进行事务增强处理，得到的将是原样的Service（没有经过事务加强处理，故而没有事务处理能力）

配置文件:
applicationContext.xml

可以让

<bean id="sessionFactory">

去配置，就不用每个都写一句。
