Now what I do, which goes against stated policy, is keep the CustomerData variables (String name, int custId, and so on) public so I can set them easily. The only time I require getters and setters for primitive types (for example, name) is if I were to read in data from a user generated form that needed to be sanitized. It's funny, too - though this type of thing goes against best practices, the primary argument for always using getters/setters (some day you might need to validate input or do other sorts of logic, and it's a pain in the ass to put that in after the fact) is pretty much 100% shattered these days, because any IDE worth a damn makes it possible to switch from public field access to getters/setters in a couple of keystrokes ("Encapsulate field" and "Inline method" are typically all you need). Though it's worth keeping in mind, most of the Java best practices tend to assume that you're writing code that other people will have to use, people whose codebases you won't have access to after you release your code, and that's a much more difficult context to program in. It requires a lot more bureaucratic nonsense to leave your API flexible when you have to worry about breaking other people's code with each edit you make, and extreme paranoia is more than justified when that's what you're worrying about.
