You could put everything in one class. You could organize by feature. You could follow some informal convention that made sense to you at the time. But Spring Boot has a well-established pattern that most serious projects follow: <strong>three-layer architecture</strong>, separating the code into Controller, Service, and Repository layers.</p> <p>This isn&rsquo;t arbitrary organization. Each layer has a specific responsibility and talks only to its adjacent layers. The result is code that&rsquo;s easier to test, easier to change, and much easier for a new developer to navigate.</p>
