I am using Spring and Thymeleaf. Thanks to xerx593, I was able to get it working so I updated this question to show the working code.
Here is my application class
package com.propfinancing.www;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import nz.net.ultraq.thymeleaf.layoutdialect.LayoutDialect;
@Controller
@SpringBootApplication
public class PfWebApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(PfWebApplication.class, args);
}
@Bean
public LayoutDialect layoutDialect() {
return new LayoutDialect();
}
@GetMapping("/page1.html")
public String page1() {
return "page1";
}
}
Next, I create a layout.html file in src/main/resources/templates/layout.html
<!DOCTYPE html>
<html lang="en" xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout">
<body>
This is the layout template
<div layout:fragment="content">
<p>This is were the content will go</p>
</div>
</body>
</html>
And fin ally, I created /ser/main/resources/templates/page1.html to use the template:
<!DOCTYPE html>
<html lang="en"
xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout"
layout:decorate="~{layout}">
<body>
<div layout:fragment="content">
This is the content of page 1.
</div>
</body>
</html>
When I go to http://dev.propfinancing.com/www/page1.html, it gives me the template driven output I was expecting.
Thanks! Neil

The most obvious mistake:
I created a simple html page called
page1.htmlin mysrc/main/resources/staticdirectory
(This is super for (spring-web) static content, but...)
And finally, I updated my
page1.htmlto use the template...
Updating is not enough, you have to also move it to a configured template location! So moving the file to src/main/resources/templates/ (default location, issuing same browser request,) will hopefully/probably produce the desired result(, or at least throw an exception).
In short: src/main/resources/static directory is not intended for templates! (It can still be configured, but this would be very strange/hacky/bunch full of "side effects"!?).
Ok, the 404, can be fixed (simply) with:
@Controller // !
@SpringBootApplication
public class ThymeleafTestApplication {
public static void main(String[] args) {
SpringApplication.run(ThymeleafTestApplication.class, args);
}
@GetMapping("/page1.html") // !!
public String page1() {
return "page1"; // returning the view name
}
// ...
}
i.e. by providing a "controller" for this "view".
Or by configuring:
@SpringBootApplication
public class PfWebApplication // extends ...
implements WebMvcConfigurer {
@Override
public void addViewControllers (ViewControllerRegistry registry) {
ViewControllerRegistration r = registry.addViewController("/page1.html");
r.setViewName("page1");
// r.set...
}
...
One important thing is, that:
@Bean
public LayoutDialect layoutDialect() {
return new LayoutDialect();
}
is the "auto-configuration" approach, which equips us with "all the spring (boot) magic".
Whereas:
@Bean
public SpringTemplateEngine templateEngine() {
SpringTemplateEngine templateEngine = new SpringTemplateEngine();
templateEngine.addDialect(new LayoutDialect());
return templateEngine;
}
..is the "DIY" approach, and we'd have to tune (like e.g. spring-boot does).
