Re: Modifying session attributes in Struts 2
Hi,
I think the best solution is to implement SessionAware interface and
setSession() method, then you will either add or remove values from
map. Like below:
public class IndexAction implements Action, SessionAware {
private MapString,Object session;
public void setSession(MapString,Object session) {
this.session = session;
}
public String execute() {
session.put(key, Some Value);
return SUCCESS;
}
public String doCheck() {
return SUCCESS;
}
}
snippet from struts.xml
package name=myPackage extends=struts-default
action name=index class=pl.org.lenart.s2demo.IndexAction
result/jsp/index.jsp/result
/action
action name=check class=pl.org.lenart.s2demo.IndexAction
method=doCheck
result/jsp/index.jsp/result
/action
/package
index.jsp to test session value
html xmlns=http://www.w3.org/1999/xhtml; xml:lang=en lang=en
head
titleIndex/title
s:head /
/head
body
s:property value=#session.key/
/body
/html
Go to http://localhost:8080/context/index.action and you will see
the value from session, then go to
http://localhost:8080/context/check.action and once again you will
see the same value. Go to some other page in Internet and then come
back to http://localhost:8080/context/check.action, once again you
will see the same ;-)
Your action is free from hard coded dependency to ActionContext. I
check this and it's working, I'm using Struts 2.1.3-SNAPSHOT
