Documentation should be complete, accurate, and follow Spring Framework conventions. Ensure your Javadocs include:

  1. Clear and accurate descriptions that precisely explain behavior and purpose ```java /**
  2. Complete parameter documentation for all parameters, especially in interfaces ```java /**
  3. Class-level Javadoc for all public classes and interfaces

  4. Format standards:
  5. Contextual information about when and how to use the API: ```java /**
  6. Clear behavioral documentation for methods with special handling: ```java /**

Documentation should be specific to the code at hand rather than copied from similar classes, and should clarify edge cases and expected behaviors.
