Thymeleaf syntax: A beginner's guide
Thymeleaf is a modern server-side Java template engine that allows developers to create dynamic web pages with ease. It is a powerful tool that simplifies the process of creating web pages by providing a simple and intuitive syntax. In this beginner's guide, we will explore the basics of Thymeleaf syntax and how to use it to create dynamic web pages.
What is Thymeleaf?
Thymeleaf is a Java-based template engine that allows developers to create dynamic web pages. It is an open-source tool that is widely used in web development. Thymeleaf is designed to work seamlessly with Spring MVC, a popular Java web framework.
Thymeleaf syntax
Thymeleaf syntax is simple and easy to understand. It uses HTML-like tags to create dynamic web pages. Thymeleaf tags are prefixed with the "th" namespace. The most commonly used Thymeleaf tags are:
-
th:text: This tag is used to display text on a web page. It can be used to display dynamic data from a database or a Java object.
-
th:if: This tag is used to conditionally display content on a web page. It can be used to show or hide content based on a condition.
-
th:each: This tag is used to iterate over a collection of objects and display them on a web page.
-
th:href: This tag is used to create hyperlinks on a web page. It can be used to create dynamic links that point to different pages based on user input.
Thymeleaf example
Let's take a look at a simple Thymeleaf example. Suppose we have a Java object called "Person" with two properties: name and age. We want to display the name and age of a person on a web page using Thymeleaf.
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>Thymeleaf Example</title>
</head>
<body>
<h1>Person Details</h1>
<p th:text="${person.name}"></p>
<p th:text="${person.age}"></p>
</body>
</html>
In the above example, we have used the "th:text" tag to display the name and age of a person. The "${}" syntax is used to access the properties of the "person" object.
Conclusion
Thymeleaf is a powerful tool that simplifies the process of creating dynamic web pages. Its simple and intuitive syntax makes it easy for developers to create web pages without having to write complex code. In this beginner's guide, we have explored the basics of Thymeleaf syntax and how to use it to create dynamic web pages. With Thymeleaf, you can create beautiful and dynamic web pages with ease.
