Full Stack JavaScript Techdegree Graduate 50,856 PointsHow does the application know it should use Thymeleaf?
So after finishing this course I am wondering how the application knows that it should use Thymeleaf. Flying over the code the only reference to Thymeleaf that I can find is as a dependency in the 'build.gradle' file.
I would have expected something like this in 'AppConfig.java'
import org.thymeleaf.TemplateEngine;
SpringApplication.run(AppConfig.class, TemplateEngine.getTemplateEngine(), args);
which tells Spring to use Thymeleaf, but apparently this is not happening.
Is it that this code in the 'build.gradle' file
dependencies {
compile 'org.springframework.boot:spring-boot-starter-thymeleaf'
}
not only fetches Thymeleaf, but also directly integrates it into Spring?
Kind Regards, Florian

Treehouse Guest TeacherGreat question, Florian. This is Spring Boot at work. There are a number of items for which Spring Boot provides auto-configuration, and template engines are one of them. What happens is that Spring Boot (with SpringApplication.run) scans the classpath, and upon seeing Thymeleaf, the auto-configuration is executed. Check out this page for supported template engines.
Spring Boot is quite powerful in this way. Expect to see more courses and workshops on Treehouse that showcase its "magic"!
