Thymeleaf + static resource + @ResponseBody
Question
In Spring Boot, I've got the simplest controller ever, returning my view name:
@Controller
public class HelloController {
@RequestMapping("/hello")
public String hello() {
return "helloworld.html";
}
}
My helloworld.html file is placed in resources/static directory:
<html>
<body>
Hello world!
</body>
</html>
And it works just fine - typing localhost:8080/hello prints "Hello world!" in browser.
Then I add Thymeleaf dependency to pom.xml , rerun app and get TemplateInputException when typing the same address in browser. Which is fine I guess, as now the resources are searched by default in resources/templates directory.
What I find weird, is when I add @ReponseBody annotation to controller method:
@Controller
public class HelloController {
@RequestMapping("/hello")
@ResponseBody
public String hello() {
return "helloworld.html";
}
}
Everything works again, I get "Hello world!" in browser. But as I know, the @ResponseBody annotation is to put the returned value as a body of the response. So why it miraculously caused that the view file can be found again?

I tested your code and I do not get "Hello World" as response with thymeleaf and html placed under static. But I get printed the string
"helloworld.html" with annotated @ResponseBody
as your controller method returns a String which in your case is the misleading "helloworld.html"
