Creating custom composite constraints
- [Instructor] So, let's jump right back into the code and create a composite constraint. If you remember, a composite constraint is built from already existing constraints, so it makes sense to look through the project's code to find where I am already using multiple annotations on a single field, and replace it with a custom composite constraint. I know that the transaction class has a field called price limit that has three constraints on it. Now, I want to replace those three constraints with just one composite constraint, which I think I'll call price limit. So, I'm going to create an annotation and I'm going to call it price limit. In order to organize my constraints, I will create a new package called constraints in the model package. So, I'll just go over here, new package, and just call it constraints. Now I need to create my constraint. That's new, Java class, and my new constraint is going to be called price limit. Now remember, in order to create an annotation I have to…
