Spring Boot cannot return html file-CodePudding

Although I change @Controller to @RestContoller, it prints not index.html but "index"

It should bring html file in templates folder but it doesn't work

I also tried to add some properties

spring.thymeleaf.prefix=/templates
spring.thymeleaf.suffix=.html

in application.properties and its still not working

Thanks for help in advance

CodePudding user response：

Remove:

spring.thymeleaf.prefix=/templates

and just add this lines:

spring.thymeleaf.cache=false
spring.thymeleaf.mode=HTML
spring.thymeleaf.suffix=.html

Make sure your pom contains thymeleaf dependency

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

Place the templates under src/main/resources/templates folder. The default extension is .html

Make sure your controller has @RequestMapping annotation

@Controller
@RequestMapping("/")
class MainController {

  @GetMapping
  public String viewHomePage() {
    return "index";
  }
}

Remove all configurations from application.properties
