Question

我在java web项目中使用struts 2。我想将Action成功重定向到另一个jsp但它不起作用。这是我的代码：

public class ConfigurerDureeStockageAction extends ActionSupport implements ServletRequestAware{
private final static Logger logger = Logger.getLogger(ConfigurerDureeStockageAction.class);
    private static final long serialVersionUID = 1L;

    private HttpServletRequest request;

    public void setServletRequest(HttpServletRequest request){
            this.request = request;
        }

    public String execute()throws Exception{
        logger.debub("Execute SUCCESS");
        return SUCCESS;

        }

        public String savePeriod(){
            logger.debub("savePeriod SUCCESS");
            return SUCCESS;
        }

}

我的struts.xml是

<action name="AdminIndex" class="fr.si2m.occ.web.actions.admin.AdminIndexAction"
            method="execute">
            <result name="success">adminIndex.jsp</result>
        </action>
    <action name="ConfigurerDureeStockageSave" class="fr.si2m.occ.web.actions.admin.ConfigurerDureeStockageAction"
                method="savePeriod">
                <result name="success">adminIndex.jsp</result>
            </action>

我试试这个

<action name="ConfigurerDureeStockageSave" class="fr.si2m.occ.web.actions.admin.ConfigurerDureeStockageAction"
            method="savePeriod">
            <result name="success" type="redirect"> 
             <param name="location">adminIndex.jsp</param >
            </result>
        </action>

和这个

<action name="ConfigurerDureeStockageSave" class="fr.si2m.occ.web.actions.admin.ConfigurerDureeStockageAction"
            method="savePeriod">
            <result name="success" type="redirect">
            <param name="actionName">AdminIndex</param>
            </result>
        </action>

最后一个配置给出了以下错误：

一直不工作。我的问题是： 1-为什么配置<result name="success">adminIndex.jsp</result>不起作用？ 2-为什么配置

<result name="success" type="redirect"> 
                 <param name="location">adminIndex.jsp</param >
                </result>

不起作用？ 3-为什么我收到配置错误

<result name="success" type="redirect">
            <param name="actionName">AdminIndex</param>
            </result>

？ AdminIndex操作在struts.xml中声明。我很迷惑。有人可以帮我吗？

Answer 1

你的问题是你不应该使用属性<param name="actionName">AdminIndex</param>，这是解决方案：

<result name="success" type="redirectAction">
    <param name="actionName">AdminIndex</param>
</result>

关于文档Struts2 Redirect Action Result Type，您应该使用redirectAction代替redirect

回答你的问题：

请提供更多详细信息。

试试这个（假设您的命名空间配置正确）：

<action name="ConfigurerDureeStockageSave" class="fr.si2m.occ.web.actions.admin.ConfigurerDureeStockageAction" method="savePeriod">
    <result name="success" type="redirect"> 
        <param name="location">adminIndex.action</param >
    </result>
</action>

或

<action name="ConfigurerDureeStockageSave" class="fr.si2m.occ.web.actions.admin.ConfigurerDureeStockageAction" method="savePeriod">
    <result name="success"> 
        <param name="location">adminIndex.jsp</param >
    </result>
</action>

因为结果类型redirect没有属性actionName，所以您应该使用具有此属性的redirectAction结果类型

Struts 2重定向到另一个jsp
