spring mvc + mybatis + spring aop声明式事务管理没有作用
在最近的一个项目中,采用springMVC、mybatis,发现一个很恼人的问题:事务管理不起作用!!网上查阅了大量的资料,尝试了各种解决办法,亦未能解决问题!
spring版本:3.0.5
mybatis版本:3.2.2
1、applicationContext.xml配置:
[html] view plain copy print?
- <context:annotation-config />
- <!-- 引入jdbc属性配置文件 -->
- <context:property-placeholder location="classpath:jdbc.properties" />
- <!-- 数据源 -->
- <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">

由于之前没用过springMVC,对其原理一知半解,一直在考虑是不是aop配置出错等等无关问题,结果破费周折,未能解决!
今天,偶然间看到一篇文章,颇有启发:
[html] view plain copy print?
- 由于采用的是SpringMVC、 MyBatis,故统一采用了标注来声明Service、Controller
- <span style="color:#FF0000;"><strong>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)</strong></span>,所以我们必须在root-context.xml中不扫描Controller,配置如下:
- <!-- 自动扫描组件,这里要把controler下面的 controller去除,他们是在spring3-servlet.xml中配置的,如果不去除会影响事务管理的。 -->
- <context:component-scan base-package="com.sence">
- <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" />
- </context:component-scan>
- 在servlet-context.xml中扫描Controller同时不扫描Service,配置如下:
- <!-- 扫描所有的controller 但是不扫描service-->
- <context:component-scan base-package="com.sence">
- <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
- <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service" />
- </context:component-scan>
按照上述,修改了配置文件,将service的扫描放在applicationContext.xml中,controller的扫描放在springMVC.xml中,
applicationContext.xml中添加:
[html] view plain copy print?
- <context:component-scan base-package="com.wtas">
- <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" />
- </context:component-scan>
springMVC.xml中修改:
[html] view plain copy print?
- <!-- 扫描所有的controller(@Controller注解) 但是不扫描service(@Service注解,如果你在java类上使用的是@Component,下面的org.springframework.stereotype.Service要改为org.springframework.stereotype.Component,
- 但是这样就有一个问题,因为Component已经包含了Controller,这样的话,也就是将Controller也排除了,所以我们在定义组件的时候尽量不要使用Component,而要使用Service)-->
- <context:component-scan base-package="com.wtas">
- <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
- <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service" />
- </context:component-scan>
