Spring boot app showing 404 for index.html

Question

I have a Spring boot application and a static index.html file located in src/main/resources/static

my controller is straight forward and looks like this

@Controller
@Log4j
public class StartController {

    @Autowired
    OwnerRepository ownerRepository;

    @RequestMapping("/")
    public String index() {
        return "index";


    }

}

my only configuration is the main one and it only has the @SpringBootApplication Im getting 404 when I hit the URL, as per my understanding no further configuration is needed by the way in the logs on the startup im seeing the following

URI Template variables for request [/index] are {}

here is my POM

Answer 1

On your pom.xml i didn't see any template engine like Thymeleaf, Velocity ecc but you have spring-boot-starter-web, so basically you resource folder its configurated, but you should put your file index.html on templates folder. Static folder serve to contain your asset files.

If you are working local, try: localhost:8080/ or localhost:8080/alquifacil/ assuming you are using port 8080 or add a template engine dependency in pom.xml like Thymeleaf

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
