When a th:if element stays hidden despite a non‑null model value, the cause is usually a null‑sensitive OGNL/SpEL expression or a global setting that forces null checks.
Learn when to use th:replace versus th:insert for Thymeleaf page layouts, plus how fragment parameters and template caching affect rendering.
Diagnose why edited Thymeleaf templates don't update in Spring Boot. Learn to identify caching causes, verify resolver beans, and apply environment-specific fixes.
Learn how Thymeleaf Layout Dialect lets Spring developers define a base page shell once and inject page-specific content, while keeping HTML prototypes valid and avoiding nested-decoration performance traps.
Stop duplicating HTML headers and footers. Learn how to use the Thymeleaf Layout Dialect to implement template inheritance for cleaner, more maintainable Java web applications.
Default Thymeleaf escaping does not protect JavaScript or URL contexts, and disabled caching hurts production performance. This architecture note covers the trust boundary, cache invalidation, and operational checks.
Stop repeating headers and footers in every HTML file. Learn how to use the Thymeleaf Layout Dialect to implement a decorator pattern for cleaner, maintainable Spring Boot templates.
Learn how to define Thymeleaf fragments with th:fragment, reuse them via th:insert/th:replace, pass parameters, and avoid common pitfalls like deprecated th:include and parameter shadowing.
Thymeleaf’s natural templating feature lets designers open raw HTML files in a browser and see a realistic prototype, while preserving Thymeleaf attributes for later rendering. Learn how to set up natural templates, avoid pitfalls, and keep design and development in sync.
