spring mvc nested model validation
- by hguser
I have two models : User,Project
public class Project{
private int id;
@NotEmpty(message="Project Name can not be empty")
private String name;
private User manager;
private User operator;
//getter/setter omitted
}
public class User{
private int id;
private String name;
//omit other properties and getter/setter
}
Now, when I create a new Project, I will submit the following parameters to ProjectController:
projects?name=jhon&manager.id=1&operator.id=2...
Then I will create a new Project object and insert it to db.
However I have to validate the id of the manager and operator is valid,that's to say I will validate that if there is matched id in the user table.
So I want to know how to implement this kind of validation?
