Action property of interface type
- by Daniel
Hi, guys.
With my understading, the nature of a Action is that properties can be pushed w/ request parameter values. And, one wonderful feature is that Struts2 allows you to directly populate parameter values against Class type property ;)
Assuming there exists a Action and property class as below,
class Action extends ActionSupport {
User user;
@Action(value="hello" {@result=(.......)})
public void execute() {
........
}
.....
public void setUser(User user) {
this.user = user;
}
public User getUser() {
return this.user;
}
}
class User {
String name;
.....
public void setName(String name) {
this.name = name;
}
public String getName() {
return this.name;
}
}
you could populate User class property by doing like this.
http://...../hello.action?user.name=John or via jsp page
Then, I realize that there are actually people make an Action property as a Interface type. My question is what is the reason behind this. If there is a sample code demonstrating it will be great.
Thanks in advance!
