因为Struts2是线程安全的，每次请求的时候都会创建一个Action实例，在与spring集成的时候，基于注解，必须在控制器中加入@Scope("prototype")代码。
再研究Struts2的时候出现以下问题：
Java代码

struts.xml中是这样配置的
Java代码
- <context:component-scan base-package="net.shopin"/>
- <action name="*" class="LogAction" method="{1}">
- <result name="login">/WEB-INF/page/member/login.jsp</result>
- </action>
- <context:component-scan base-package="net.shopin"/>
- <action name="*" class="LogAction" method="{1}">
- <result name="login">/WEB-INF/page/member/login.jsp</result>
- </action>
以为以上用到了spring的自动扫描工程中的bean，所以class那写的不是bean的全名，研究了好久才发现原来class那写的时候，***个字母必须小写，改后，问题解决……
修改后的struts.xml
Java代码
- <context:component-scan base-package="net.shopin"/>
- <action name="*" class="logAction" method="{1}">
- <result name="login">/WEB-INF/page/member/login.jsp</result>
- </action>
