representation response spring-boot html

    我是spring新手,这是spring boot应用程序中的mediatype不匹配问题,但不确定根本原因是什么。我想使用响应对象生成HTML响应,在本例中,我使用了serverError()。 

    import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

@RestController
@RequestMapping("/htmlmaps")
public class HTMLMAPs {
    @RequestMapping(value="/do", produces =MediaType.TEXT_HTML, method= RequestMethod.GET)
    public Response doReturnHtml(){
        return Response.serverError().type(MediaType.TEXT_HTML).build();
    }
}

    当我击球时 http://localhost:8080/htmlmaps/do 应用程序抛出以下错误(跟踪日志):

    springboot似乎不能很好地与Response类配合使用,因此我尝试使用ResponseEntity,但效果不错。我希望这可以帮助那些将spring项目迁移到springboot的人使用响应类填充HTML内容。 

    @RestController
@RequestMapping("/htmlmaps")
public class HTMLMAPs {
    @RequestMapping(value="/do", produces =MediaType.TEXT_HTML, method= RequestMethod.GET)
    public ResponseEntity<String> doReturnHtml(){
        return new ResponseEntity<String>("Error", responseHeaders, HttpStatus.CREATED);
    }
}
