How to solve the issue of th:text tag not working in Thymeleaf.

There could be several reasons why the th:text tag in Thymeleaf is not working:

1. Make sure to include the correct Thymeleaf namespace at the beginning of the HTML file. Ensure that the correct Thymeleaf namespace has been included as shown below:
2. Include the Thymeleaf namespace in the HTML file.
3. Thymeleaf expressions were not used correctly. It is necessary to use Thymeleaf expressions in the th:text tag to reference variables or execute expressions. For example, if you want to display the value of a variable, you can use ${variableName}. Make sure to use Thymeleaf expressions correctly in the th:text tag.
4. Display the title in the heading section.
5. It could be a configuration issue with Thymeleaf. Check the Thymeleaf configuration file to make sure the template resolver is correctly set up. For example, if you’re using Spring Boot, you can add the following configuration in the application.properties or application.yml file.
6. spring.thymeleaf.mode is set to HTML, and spring.thymeleaf.cache is disabled.
7. These configurations ensure that the Thymeleaf template resolver reloads templates in real time during the development process, and disables template caching.

If the issue still cannot be resolved, you can check the log files for any relevant error messages, or provide more code and error information in the issue description to better help you solve the problem.
