@ Resultpath of struts2

From: http://blog.csdn.net/yandufeng/article/details/8105495

 

Here I want to add: To understand annotation, the best way is to look at the source code, Struts Convention source code in the struts2-convention-plugin-2.1.6.jar

 

In struts2, @ resultpath annotation is used to control the struts2 where to find the storage JSP page, by default it finds the JSP page in the WEB-INF/content/directory

@ Resultpath example

An action class that sets/user as namespace to jump to the/pages/login. jsp page

 

1 @Namespace("/User")2 @Result(name="success",location="pages/login.jsp")3 public class LoginAction extends ActionSupport{
4 }

 

Access it

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

 

Struts 2 will find the "login. jsp" from the default location

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

 

Custom resultpath

1 @Namespace("/User")2 @ResultPath(value="/")3 @Result(name="success",location="pages/login.jsp")4 public class LoginAction extends ActionSupport{
5 }

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

/Struts2Example/pages/login.jsp

 

Global @ resultpath

 

@ Resultpath is only applicable to the class level. To render it, you can configure it in struts. xml

Struts. xml
