VisualizaçõesHow to stop my action from executing when I refresh my page?
Hello community I have the following problem, I am working on a project with JSP and Struts technology, I am really new because it is an old technology but it is what I had to work with.
I have the problem that calls are being made to the action when I refresh my page, I understand this is because in my URL is the last action that I send to call, so it is making a call back to that action, I have more than one form within my JSP which have different actions, I do not know if this is correct or have to change them to ajax or is there any way to solve it?
I have already added a POST method for the actions but it still has not worked.
My actions in configuration file:
<action name="plantillasAction_*" method="{1}" class="com.xxx.action.ActionPlantillas">
<result name="success">/jsp/plantillas/ResultTemplates.jsp</result>
<result name="templateUpload">/jsp/plantillas/CreateCoordinates.jsp</result>
<result name="saveCoordinates">/jsp/plantillas/SaveCoordinates.jsp</result>
<result name="updateCoordinates">/jsp/plantillas/UpdateCoordinatesTemplate.jsp</result>
<interceptor-ref name="defaultSecurityStack">
<param name="tokenSession.excludeMethods">init,templateFileUpload,processNavigator,
addCoordinateTemplate,deleteCoordinateToSave,saveTemplate,
deleteTemplate,viewUpdateTemplate,addCoordinatesTemplateUpdate,
searchTemplates,processUpdateNavigator</param>
</interceptor-ref>
<allowed-methods>
templateFileUpload,
processNavigator,
addCoordinateTemplate,
deleteCoordinateToSave,
saveTemplate,
deleteTemplate,
viewUpdateTemplate,
addCoordinatesTemplateUpdate,
processUpdateNavigator,
init,
searchTemplates
</allowed-methods>
</action>
My CreateCoordinates.jsp:
<%@ page contentType="text/html" pageEncoding="UTF-8"%>

<%@ taglib prefix="sj" uri="/struts-jquery-tags"%>

When I enter my JSP this is the URL:
When I press any button of my first form it changes the URL to
If I refresh my page there, the action name is plantillasAction_processUpdateNavigator ,what I want in this case is to execute the action plantillasAction_viewUpdateTemplate.
My ActionPlantillas.java:
public class ActionPlantillas extends ActionSupport implements ServletRequestAware {
private static Logger logger = LogManager.getLogger(ActionPlantillas.class);
private HttpServletRequest request;
public String viewUpdateTemplate() {
//OPERATIONS
return "updateCoordinates";
}
public String processUpdateNavigator() {
//OPERATIONS
return "updateCoordinates";
}
}

Create a SuccessAction with redirectAction class.
<action name="plantillasAction_*" method="{1}" class="com.xxx.action.ActionPlantillas">
<result name="success">/jsp/plantillas/ResultTemplates.jsp</result>
</action>
<action name="SuccessAction" class="SuccessPage">
<result name="success">/jsp/plantillas/success.jsp</result>
<action name="manual_order" class="materialTypeMasterAction" method="enquiry_process">
<result type="redirectAction">SuccessAction</result>
</action>
Like this: Prevent action resubmission
Please notice that if you do not change the URL, it will always resubmit the form. So if you implement this solution above, the url will change on success (redirectSuccess).
You don't have to really create a new success page, you can redirect to the original url/action in which the form is loaded (clean).
I hope this helps.
