标签： html spring-boot response representation

我是春天的新手，这是spring-boot应用程序中的mediatype不匹配问题，但不确定是什么原因。我想使用Response对象生成HTML响应，对于此示例，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();
    }
}

当我点击http://localhost:8080/htmlmaps/do应用程序时抛出错误（跟踪日志）：

    2017-01-20 09:18:33.174 TRACE 14400 --- [nio-8080-exec-1] .w.s.m.m.a.ServletInvocableHandlerMethod : Error handling return value [type=org.glassfish.jersey.message.internal.OutboundJaxrsResponse] [value=OutboundJaxrsResponse{status=200, reason=OK, hasEntity=false, closed=false, buffered=false}]

似乎springboot对Response类没有用，所以我尝试使用ResponseEntity而不是有效。我希望这可以帮助那些将spring项目迁移到springboot并使用Response类填充HTML内容的人。

@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);
    }
}
