Struts2 JPA 验证错误如何转发到操作而不丢失 ActionErrors 消息? [英] Struts2 JPA Validation error how to forward to action and not lose ActionErrors messages?

问题描述

我正在使用 Hibernate 验证器 4.1 来验证我的实体.

我有一个仪表板，我可以从操作 viewDashboard 访问它.在我的动作类中，我像这样设置了两个 List 的值.

<前>公共字符串执行()抛出异常{listDocteur = service.listDocteur();listUser = service.listUser();返回成功；}

在仪表板中，我有一个可以添加用户的提交按钮.

<前><action name="saveUser" class="com.test.action.CreateUserAction" method="execute"><interceptor-ref name="mybasicStackWithValidation" ><result name="input">/WEB-INF/jsp/viewDashboard.jsp</result><result name="success" type="redirectAction">viewDashboard</result>

如果我提交无效值，我会看到错误消息，但我会丢失我的 2 个列表.如果我有 type="redirectAction"，我会丢失错误消息.

在 Struts 1 中，我会在没有 redirect 的情况下转发到操作 viewDashboard.do 并且这会起作用.我如何在 Struts2 中实现这一点?

解决方案

我找到了解决方案.我必须使用 <input type="redirectAction">youraction ..

并且需要把它放在你的 SAVEAction

<前>STORE

最后，在您的 displayAction(将显示错误消息)中

<前><param name="operationMode">AUTOMATIC</param>

或恢复

I'm using Hibernate validator 4.1 to validate my Entity.

I have a dashboard that I can access from the action viewDashboard. In my action class, I set the values of two List like this.

public String execute() throws Exception {

    listDocteur = service.listDocteur();
    listUser = service.listUser();

    return SUCCESS;
}

In the DashBoard, I have a submit button that can add a User.

<action name="saveUser" class="com.test.action.CreateUserAction" method="execute">
   <interceptor-ref name="mybasicStackWithValidation" >
   </interceptor-ref>
   <result name="input">/WEB-INF/jsp/viewDashboard.jsp</result>
   <result name="success" type="redirectAction">viewDashboard</result>
</action>

If I submit an invalid value, I'll see the error messages, but I'll lose my 2 Lists. If I have a type="redirectAction", I lose the error messages.

In Struts 1, I would forward to the action viewDashboard.do without a redirect and that will works. How can i achieve this in Struts2?

解决方案

I Found a solution. I have to use <input type="redirectAction">youraction ..

and need to put this in your SAVEAction

<interceptor-ref name="store">
    <param name="operationMode">STORE</param>
</interceptor-ref>
  

and finally, in your displayAction (that will display the error messages)

<interceptor-ref name="store">
    <param name="operationMode">AUTOMATIC</param>
</interceptor-ref>

or RESTORE
