这期内容当中小编将会给大家带来有关Struts2和Spring集成小问题是怎么样的,文章内容丰富且以专业的角度为大家分析和叙述,阅读完这篇文章希望大家可以有所收获。
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>
