I'm facing a Spring Boot configuration issue I can't deal with... I'm trying to build an HelloWorld example for HbbTV with Spring Boot, so I need to serve my "index.html" page with mime-type="application/vnd.hbbtv.xhtml+xml"
my index.html will be accessed as a static page, for instance http://myserver.com/index.html?param=value.
with the following code, no matter how hard I try, I get a text/html content type.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//HbbTV//1.1.1//EN" "http://www.hbbtv.org/dtd/HbbTV-1.1.1.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>MyApp HBBTV</title>
<meta http-equiv="content-type" content="Content-Type: application/vnd.hbbtv.xhtml+xml; charset=UTF-8" />
</head>
<body>
...
</body>
</html>
So I tried to add a "home()" endpoint into a @Controller to force the correct mime-type, and that works.
@RestController
public class HbbTVController {
@RequestMapping(value = "/hbbtv", produces = "application/vnd.hbbtv.xhtml+xml")
String home() {
return "someText";
}
...
}
"That works" mean the jetty server serves me a html file with the correct content-type containing the test someText.
My next try were to replace the @RestController by @Controller (same produce config), and replace "someText" by index.html
@Controller
public class HbbTVController {
@RequestMapping(value = "/hbbtv", produces = "application/vnd.hbbtv.xhtml+xml")
String home() {
return "index.html";
}
...
}
Well, it serves my index.html correctly, but the Content-Type is wrong : text/html instead of application/vnd.hbbtv.xhtml+xml. Furthermore, I don't want to access to myserver.com/hbbtv to get index.html, but directly to myserver.com/index.html.
How could I do that ?
Thanks...

Well, finally, I found the "Spring boot compliant solution". It's the same as Jamie Birch suggested, but realized with Spring mechanisms.
Spring Boot 1:
@Configuration
public class HbbtvMimeMapping implements EmbeddedServletContainerCustomizer {
@Override
public void customize(ConfigurableEmbeddedServletContainer container) {
MimeMappings mappings = new MimeMappings(MimeMappings.DEFAULT);
mappings.add("html", "application/vnd.hbbtv.xhtml+xml; charset=utf-8");
mappings.add("xhtml", "application/vnd.hbbtv.xhtml+xml; charset=utf-8");
container.setMimeMappings(mappings);
}
}
Spring Boot 2:
@Configuration
public class HbbtvMimeMapping implements WebServerFactoryCustomizer<ConfigurableServletWebServerFactory> {
@Override
public void customize(ConfigurableServletWebServerFactory factory) {
MimeMappings mappings = new MimeMappings(MimeMappings.DEFAULT);
mappings.add("html", "application/vnd.hbbtv.xhtml+xml; charset=utf-8");
mappings.add("xhtml", "application/vnd.hbbtv.xhtml+xml; charset=utf-8");
factory.setMimeMappings(mappings);
}
}
