Thymeleaf

Thymeleaf is a Java XML/XHTML/HTML5 template engine that can work both in web (servlet-based) and non-web environments. It is better suited for serving XHTML/HTML5 at the view layer of MVC-based web applications, but it can process any XML file even in offline environments. It provides full Spring Framework integration.

In web applications Thymeleaf aims to be a complete substitute for JavaServer Pages (JSP), and implements the concept of Natural Templates: template files that can be directly opened in browsers and that still display correctly as web pages.

Thymeleaf is open-source software, licensed under the Apache License 2.0.

Features From the project's website: Thymeleaf Features Java template engine for XML, XHTML and HTML5. Works both in web and non-web (offline) environments. No hard dependency on the Servlet API. Based on modular feature sets called dialects. Dialect features (e.g.: evaluation, iteration, etc.) are applied by linking them to template's tags and/or attributes. Two dialects available out-of-the-box: Standard and SpringStandard (for Spring MVC apps, same syntax as Standard). Developers can extend and create custom dialects. Several template modes: XML: validating against a DTD or not. XHTML 1.0 and 1.1: validating against standard DTDs or not. HTML5: both XML-formed code and legacy-based HTML5. Legacy non-XML code will be automatically cleaned and converted to XML form. Full (and extensible) internationalization support. Configurable, high performance parsed template cache that reduces input/output to the minimum. Automatic DOCTYPE translations –from template DTD to result DTD– for (optional) validation of both template and result code. Extremely extensible: can be used as a template engine framework if needed. Complete documentation including several example applications.

Thymeleaf example The following example produces an HTML5 table with rows for each item of a List<Product> variable called allProducts.

<table> <thead> <tr> <th th:text="#{msgs.headers.name}">Name</th> <th th:text="#{msgs.headers.price}">Price</th> </tr> </thead> <tbody> <tr th:each="prod : ${allProducts}"> <td th:text="${prod.name}">Oranges</td> <td th:text="${#numbers.formatDecimal(prod.price,1,2)}">0.99</td> </tr> </tbody> </table>

This piece of code includes: Internationalization expressions: #{ ... } rh Variable/model-attribute evaluation expressions: ${ ... } Utility functions: #numbers.formatDecimal( ... )

Also, this fragment of (X)HTML code can be perfectly displayed by a browser as a prototype, without being processed at all: it is a natural template.
