spring3MVC 事务无法回滚问题

 搭建好Spring3MVC,用@Transactional方式进行事务管理,发现方法体内出错后事务不会回滚,依然提交成功

网上查了下了发现是spring的<context:component-scan />标签使用有问题


如果是搭建Spring3MVC,一般情况下在web.xml中有2个地方要加载spring的xml文件:
第一个地方:

<servlet>
		<servlet-name>bms</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>
				classpath*:/spring/servlet/servlet-config.xml
			</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>bms</servlet-name>
		<url-pattern>*.html</url-pattern>
	</servlet-mapping>


第二个地方:

<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>
			classpath*:/applicationContext.xml
		</param-value>
	</context-param>

	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

第一个地方是专门用来解析springmvc控制层用的,也就是controller

第二个地方是解析除controller以外的一些bean,比如datasource,service,dao,事务等

本来我们只需在第一个地方做如下配置就行了:<context:component-scan base-package="com.xx" />
但是这样配置的话对事务不起作用

因此,我们要做如下配置:
去掉原先的<context:component-scan base-package="com.xx" />东东

 

在第一个地方配置:

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

这样配置就是让spring容器只扫描controller层

 

然后在第二个地方配置:

<context:component-scan base-package="com.xx">
		<context:exclude-filter expression="org.springframework.stereotype.Controller"
			type="annotation" />
	</context:component-scan>

从字面上就看的出来,是让spring容器只扫描除了controller层以外的bean


然后还要添加几个jar包,不然启动会报asm,aspectj一些错误,需要添加的jar包如下(版本不一大致相同即可):
asm-2.2.3.jar
aspectjrt.jar
aspectjweaver.jar
cglib-nodep-2.1_3.jar

如果启动报proxy10 cannot be cast to 的错误需要在第二个地方添加:
<aop:aspectj-autoproxy proxy-target-class="true" />

 

最后贴上我的配置代码:
我的项目是spring3mvc + ibatis
