FWIW how we do this kinda thing in Able in a Stripernate kinda way
would be like this...
@UrlBinding(/user/{user})
public class UserActionBean implements ActionBean {
private User user;
@DefaultHandler
public Resolution get() {
return new ForwardResolution("/WEB-INF/views/user.jsp");
}
public Resolution save() {
}
}
Then we'd register a TypeConverter<User> which took the String of the
ID value and loaded the User via JPA/Hibernate/whatever.
i.e. the @UrlBinding would only need to extract the {foo} expressions
as Strings and inject them into the POJO like they were HTTP
parameters - using the existing type converter code.
I guess another option could be to support parameters on the action
methods - though its a bit more work to do (treating URI fragments as
pseudo http parameters is easier :)
e.g.
@UrlBinding(/user/{id})
public class UserActionBean implements ActionBean {
private User user;
@DefaultHandler
public Resolution get(String id) {
// am gonna do the conversion to a User myself here...
}
}
but it could deal with more complex use cases; where multiple values
come from the URI to do some custom query etc.
