Struts 2 @ResultPath annotation example

In Struts 2,

@ResultPath

annotation is used to control where Struts 2 will find the the stored results or JSP pages. By default, it will find the result pages from the “

WEB-INF/content/

” folder.

No idea why the Struts 2 annotation set the “

WEB-INF/content/

” as default folder, but most applications will not put the result pages in this “

WEB-INF/content/

” folder. It’s just a Struts 2 convention not a standard folder structure. I rather Struts 2 put the root path as the default folder.

@ResultPath

example

1. Default ResultPath

A login action class, set to “

/User

” namespace, and redirect to the “

pages/login.jsp

” pages.

P.S Assume the

Struts2Example

is your context servlet name

@Namespace("/User")
@Result(name="success",location="pages/login.jsp")
public class LoginAction extends ActionSupport{
}

Access it

http://localhost:8080/Struts2Example/User/login.action

Struts 2 will find the “

login.jsp

” result page from the default location

/Struts2Example/WEB-INF/content/User/pages/login.jsp

2. Custom

ResultPath

If your JSP result pages are store in other location, you are allow to change it with

@ResultPath

annotation.

@Namespace("/User")
@ResultPath(value="/")
@Result(name="success",location="pages/login.jsp")
public class LoginAction extends ActionSupport{
}

Access it again

http://localhost:8080/Struts2Example/User/login.action

Now the Struts 2 will find the “

login.jsp

” result page from different location

/Struts2Example/User/pages/login.jsp

Global

@ResultPath

The

@ResultPath

is only apply to the class level. To apply it globally, you can configure it in the

struts.xml

file.
