How to resolve the issue of thymeleaf not obtaining model values.

To troubleshoot and resolve the issue of Thymeleaf not being able to access model values, you can follow these steps:

1. Make sure the model value is set correctly in the controller. Use the Model object to add data to the model in the method that returns the view. For example: model.addAttribute(“key”, value).
2. Make sure to use the correct expression to access model values in Thymeleaf templates. Use the `${key}` format in the template to retrieve values from the model. Ensure that the key matches the key added to the model in the controller.
3. Make sure the location and naming of the Thymeleaf template files are correct. Thymeleaf by default searches for template files in the src/main/resources/templates directory. Ensure that the location and naming of the template files match expectations.
4. If you are using Spring Boot, make sure you have correctly imported the Thymeleaf dependencies. Add the following dependencies to your pom.xml file:
5. 
   org.springframework.boot
   spring-boot-starter-thymeleaf
   
6. If the issue still cannot be resolved, consider rebuilding the project and restarting the application to ensure that any changes have taken effect properly.

If the above method still cannot resolve the issue, it is advised to check the log files for any errors or anomalies. By using the information provided in the log files, the issue can be further diagnosed and resolved.
