以上是工程中原有spring配置文件。在测试事务时，事务不能回滚。原因是applicationContext.xml是主容器在扫描类中service，发现service进行事务处理。在主容器初始化后，springmvc-servlet在进行一次扫描，这次扫描是@Controller的注解bean，但是@service的bean只是作为普通bean进行处理，不进行事务处理。所有spring容器装载service的bean只是作为普通bean使用。

确认事务无法回滚的几个问题。

1.确认mysql表类型innodb类型

2.确认配置文件配置是否正确，包括：service中路径正确

3.在配置注解扫描时，主容器只扫描@service，mvc容器值扫描@controller的注解。

主容器

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

mvc容器

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