Spring 406不可接受的弹簧座WS

我正在编写一个SpringRESTWS以XML形式返回响应。下面是我的课程和pom文件

我在执行服务时遇到Http 406错误，如下所示：

 http://localhost:8080/SpringRestExample/rest/emp/dummy.xml

但是，我在执行时得到了JSON响应

http://localhost:8080/SpringRestExample/rest/emp/dummy.json 

请告知

406表示服务器无法以客户端请求的内容类型生成响应。检查HTTP请求的Accept标头，并确保它包含application/xml

---

可能它包含text/xml，这就是您应该在

@RequestMapping

注释的

生成属性中使用的内容。顺便说一句，您应该使用
org.springframework.http.MediaType
中的常量，而不是像现在这样硬编码字符串。
对于任何类型的xml转换，您都需要在模型类的顶部添加@XmlRootElement注释。我已经做了更改，运行了上面的程序并得到了结果。只需在Employee类上面添加@XmlRootElement，您就完成了。
谢谢您。我添加了accept头，当再次执行时，如果我需要在请求中传递除accept之外的任何其他头，我将收到400 Http错误（客户端发送的请求在语法上不正确（））。请告知。这应该是评论
