![]() ![]() Boolean negation (unary operator): !, not.Variable expressions are OGNL expressions –or Spring EL if you’re integrating Thymeleaf with Spring– executed on the context variables - also called model attributes in Spring jargon. Most Thymeleaf attributes allow their values to be set as or containing expressions, which we will call Standard Expressions because of the dialects they are used in. Note that the Standard and the SpringStandard dialects are almost identical, except that SpringStandard includes specific features for integrating into Spring MVC applications (like, for example, using Spring Expression Language for expression evaluation instead of OGNL).Īlso note we usually refer to features in the Standard dialects when we talk about Thymeleaf without being more specific. You can identify when these standard dialects are being used in a template because it will contain attributes starting with the th prefix, like. Out of the box, nevertheless, it comes with something called the standard dialects (named Standard and SpringStandard) that define a set of features which should be more than enough for most scenarios. It’s more like a template engine framework. Thymeleaf is very, very extensible, and it allows you to define your own sets of template attributes (or even tags) with the names you want, evaluating the expressions you want in the syntax you want and applying the logic you want. It is not a substitute for the tutorials – which are much more comprehensive – but it will teach you enough for getting the feel of the technology. This guide will take you through some of the most important concepts you need to know to understand a Thymeleaf template written in the Standard or SpringStandard dialects.
