Thymeleaf Static Resource Caching Issues

CSS or JavaScript changes don't appear after deployment. Browser caches old versions. Users see old styles or functionality.

Aggressive caching hides code updates.

Common Causes

  1. HTTP cache headers set too long
  2. Browser aggressively caches .css/.js files
  3. No cache busting (version strings in filenames)
  4. CDN cache not invalidated
  5. Service worker caching old resources

How to Fix It

Add version query string to resources: th:href=@{/css/style.css(v=${appVersion})}. Set cache headers: Cache-Control: no-cache for HTML, public max-age=3600 for static. Use content-hash in filename (style.a1b2c3d4.css). Disable cache in development: spring.web.resources.cache.period=0.
