Spring code style

Follow Spring Framework’s code style guidelines to ensure consistency across the codebase. Key rules include:

1. Import statements:
   • Use specific imports rather than wildcard imports
   • Maintain consistent import ordering
   • Avoid static imports except in specific cases
2. Field and variable references:
   • Always prefix instance field references with this.
   • Don’t declare local variables as final unless there’s a compelling reason
   • Don’t use var in production code
3. Formatting:
   • Use tabs for indentation, not spaces
   • Remove unnecessary spaces inside parentheses
   • Aim for 90 characters per line (maximum 120), with 80 for Javadoc
   • Place opening braces on the same line, else statements on a new line
4. Before submitting:
   • Run ./gradlew check to catch style violations automatically

Example of proper style:

public class MyClass {
    private final String field;

    public MyClass(String parameter) {
        this.field = parameter;
    }

    public void doSomething(String input) {
        if (input == null) {
            return;
        }
        else {
            String result = processInput(this.field, input);
            processResult(result);
        }
    }
}
