This article addresses a common problem: how to leverage Thymeleaf to load these language properties, populate dynamic values, and render them directly—without HTML templates. The Problem To set the stage, let’s consider a scenario where you have two language property files—language.properties and language_en.properties. These files contain key-value pairs for your localized strings. Here’s what one of these files looks like: [[See Video to Reveal this Text or Code Snippet]] What We Want to Achieve Use Thymeleaf to access the appropriate language property file based on user locale. Populate the placeholder {name} with a dynamic value, which you can provide as input (e.g., using a HashMap). Retrieve the final populated text as a String. The pressing question is: Is this achievable within Thymeleaf? If so, how can we set it up? The Solution Yes, achieving this is absolutely possible! Below, we’ll break down the steps you need to follow. Step 1: Configure the MessageSource Bean First, you need to configure a MessageSource bean. This bean tells Spring Boot where to find your message files. You can do this by adding the following property to your application.properties: [[See Video to Reveal this Text or Code Snippet]] This assumes your properties files are located in path/to/language (with a naming convention such as language.properties and language_en.properties). Step 2: Create a Helper Class Next, you'll want to create a helper class responsible for fetching the messages from the MessageSource. This is where the magic happens: [[See Video to Reveal this Text or Code Snippet]] Explanation of the Code Constructor Injection: This approach injects the MessageSource bean so that you can fetch localized messages when needed. translate Method: This method takes two parameters—the key for the property file and the dynamic name you would like to insert. It uses getMessage() to fetch the localized string and populate it with the specified name, using the English locale as our default. Step 3: Adjust for Locale You may want to adapt your application to determine the user’s locale dynamically rather than hard-coding it to English. The method getMessage() offers versatility in that regard—you can use the proper locale based on your application’s session or system settings. Final Thoughts With the steps outlined above, you can effectively utilize Thymeleaf in conjunction with Spring Boot to manage multi-language support in your application. By using properties files and a simple helper class, you can populate localized strings dynamically and present them as needed. This strategy not only makes your application more user-friendly by catering to a diverse user base, but it also simplifies the process of maintaining language files as you expand your app. Now, you’re equipped with the knowledge to start integrating language properties in your Thymeleaf templates!
