Struts2和Spring集成小問題是怎么樣的

這期內容當中小編將會給大家帶來有關Struts2和Spring集成小問題是怎么樣的，文章內容豐富且以專業的角度為大家分析和敘述，閱讀完這篇文章希望大家可以有所收獲。

因為Struts2是線程安全的，每次請求的時候都會創建一個Action實例，在與spring集成的時候，基于注解，必須在控制器中加入@Scope("prototype")代碼。

再研究Struts2的時候出現以下問題：

Java代碼

struts.xml中是這樣配置的

Java代碼

<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>

以為以上用到了spring的自動掃描工程中的bean，所以class那寫的不是bean的全名，研究了好久才發現原來class那寫的時候，***個字母必須小寫，改后，問題解決……

修改后的struts.xml

Java代碼

<context:component-scan base-package="net.shopin"/>     <action name="*" class="logAction" method="{1}">                 <result name="login">/WEB-INF/page/member/login.jsp</result>             </action>
