I would like to get a running Springboot Application with Java Backend.
I tried an example application of the web. I runs on Tomcat. I can install the maven, and run the jar. I can open the Localhost:8082/ and it returns some.json document.
What i cannot do is to jump to some.html page. Is there an error in my structure?
Strucure:
HomeController.java
package com.example.demo.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HomeController {
@RequestMapping("/home")
public String home() {
return "index";
}
@RequestMapping("/test")
public String test() {
return "test";
}
}
application.properties:
spring.mvc.view.prefix = /views/
spring.mvc.view.suffix = .html
server.port=8082
Application:
@SpringBootApplication
public class BootDemoApplication {
@Autowired
UserRepository userRepository;
public static void main(String[] args) {
SpringApplication.run(BootDemoApplication.class, args);
}
}
}
Run-Output:
The mapping should work:
2020-12-03 10:09:23.444 INFO 4764 --- [ main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/test]}" onto public java.lang.String com.example.demo.controller.HomeController.test()
2020-12-03 10:09:23.446 INFO 4764 --- [ main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/home]}" onto public java.lang.String com.example.demo.controller.HomeController.home()
I have tried to change the application.properties into:
spring.mvc.view.prefix = resources/static/views/
and
spring.mvc.view.prefix = /static/views/
this had no effect on the result.
Is there an error, i cannot see?
Thanks

You can use thymeleaf as template engine and put your views under the templates folder src/main/resources > templates, thanks
