I have like following jsp.I send some data via form and execute Action,
case.jsp
before action:${CasePostFormBean.subject}
<s:action var="ServletHelperAction" name="login-user-to-bean" namespace="/servlet-helper"></s:action>
after action:${CasePostFormBean.subject}
<input name="CasePostFormBean.subject" value="${CasePostFormBean.getSubject()}" form="formCasePost">
<form method="post" id="formCasePost" submit="case-create"></form>
servlethelper.jsp
<html></html>
CasePostAction.java
public class CasePostAction extends ActionSupport implements SessionAware {
@Getter @Setter
private CasePostFormBean casePostFormBean = new CasePostFormBean();
@Action(value = "case-create", results = {
@Result(location = "case.jsp")
})
public String register() {
this.casePostFormBean.setSubject("success to send form");
return SUCCESS;
}
}
}
public class ServletHelperAction extends ActionSupport implements SessionAware {
// Beans
@Getter @Setter
private UserParamsBean userParamsBean = new UserParamsBean();
@Action(value = "login-user-to-bean", results = {
@Result(location = "servlethelper.jsp")
})
public String loginUserToBean() {
final MstUserModel mstUserModel = new MstUserModel(this.dbManager.getSqlSession());
if (this.session.get("userParamsBean.userCode") != null) {
this.userParamsBean.setUserCode(this.session.get("userParamsBean.userCode").toString());
Map<String, Object> loginUser = mstUserModel.selectUserOne(1, this.userParamsBean.getUserCode()).get(0);
this.userParamsBean.setUserName(loginUser.get("name").toString());
}
return SUCCESS;
}
}
After input input value and after button submitted, like following was shown.
before action: success to send form
after action: input value
Out put is like follows, When I execute another action via <s:action> the value stack seems to be changed.
Seems that after <s:action> these sent data was recaptured by value stack.
My desired result is like
before action: success to send form
after action: success to send form
What is the root cause of this?
If you set some bean to the action object, then it belongs to it until you reference it someare else, i.e. a session map. Since you have to implement a
SessionAwareinterface onCasePostAction. Then you putCasePostFormBeaninto the session map. In this way the scope of the object will be a session scope until you remove it from the session or invalidate a session map.In the JSP you use EL expression to search for the
CasePostFormBean. Currently you keep it in the action bean and a scope belongs to theactionscope.The
actionscope is similar to therequestif you don't instantiate other actions in the request like<s:action>. Each action has its ownactionscope and therefore aValueStack.Change the code
When a result is executed you should reference this object directly from the session.
