SpringMVC MyBatis 配置

693579551

　　spring mvc 配置事务时，总是不回滚 报 Closing non transactional SqlSession的错
　　因为spring的扫描注入需要在两个地方进行配置
　　一个是servle的配置文件xml中 一个是springcontext的配置xml中  

servlet的xml配置文件中需要添加的是

<!-- 注解探测器 -->
<context:component-scan base-package="com.mtz">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/>
</context:component-scan>
 

 


　　1在springmvc-context.xml的配置中 

写道

<!-- 注解探测器 ， 在JUnit测试的时候需要 -->
<context:component-scan base-package="com.mtz">
</context:component-scan>
 

 
　　 要添加 service的排除掉
　　2在设置Spring容器加载配置文件也要添加扫描配置

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:config/spring/applicationContext-*.xml</param-value>
</context-param>
　　 即在applicContext-common的xml中也添加扫描配置

写道

<context:component-scan base-package="com.mtz">
</context:component-scan>

原来一直不能回滚是因为没有在servlet的xml文件配置排除service的设置。
