I'm using spring boot 1.5.2 and my spring rest controller looks like this
@RestController
@RequestMapping("/")
public class HomeController {
@RequestMapping(method=RequestMethod.GET)
public String index() {
return "index";
}
}
when I go to http://localhost:8090/assessment/ it reaches my controller but doesn't return my index.html, which is in a maven project under src/main/resources or src/main/resources/static. If I go to this url http://localhost:8090/assessment/index.html, it returns my index.html. I looked at this tutorial https://spring.io/guides/gs/serving-web-content/ and they use thymeleaf. Do I have to use thymeleaf or something like it for my spring rest controller to return my view?
My application class looks like this
@SpringBootApplication
@ComponentScan(basePackages={"com.pkg.*"})
public class Application {
public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class, args);
}
}
When I add the thymeleaf dependency to my classpath I get this error (500 response code)
org.thymeleaf.exceptions.TemplateInputException: Error resolving template "index", template might not exist or might not be accessible by any of the configured Template Resolvers
I guess I do need thymeleaf? I'm going to try and configure it properly now.
It works after changing my controller method to return index.html like this
@RequestMapping(method=RequestMethod.GET)
public String index() {
return "index.html";
}
I think thymeleaf or software like it allows you to leave off the file extension, not sure though.

RestController annotation returns the json from the method not HTML or JSP. It is the combination of @Controller and @ResponseBody in one. The main purpose of @RestController is to create RESTful web services. For returning html or jsp, simply annotated the controller class with @Controller.

Your example would be something like this:
Your Controller Method with your route "assessment"
@Controller
public class HomeController {
@GetMapping("/assessment")
public String index() {
return "index";
}
}
Your Thymeleaf template in "src/main/resources/templates/index.html"
<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">

<title>Getting Started: Serving Web Content</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<p>Hello World!</p>
