java - 泽西声明式链接不起作用

Question

我尝试使用 Jersey 创建一个完整的网络服务。我想在该请求的响应中提供一个链接:

GET /mac/ws/gtm HTTP/1.1
Host: localhost:8080
Accept: application/json
Cache-Control: no-cache

我希望响应是:

HTTP/1.1 200 OK
link: </dossiers>;rel=dossiers

{
    "message": "Hello"
}

但是响应是:

HTTP/1.1 200 OK

{
    "message": "Hello"
}

链接未生成!

看看我的 Gtm 资源:

@Component
@Path("/gtm")
public class GTmRessource
{
    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public GTm getJson()
    {
        GTm gtm = new GTm();
        return gtm;
    }
}

还有我的 Gtm 实体

@XmlRootElement()
@Link(value = @Ref(value = "/dossiers", method = "get"), rel = "dossiers")
public class GTm
{
    String message = "Hello";

    public String getMessage()
    {
        return message;
    }

    public void setMessage(String message)
    {
        this.message = message;
    }
}

怎么了？

感谢您的帮助。通过

参见 Declarative Hyperlinking: Configuration

您需要以编程方式添加 LinkFilter:

resourceConfig.getContainerResponseFilters().add(LinkFilter.class);

或通过 web.xml

<init-param>
  <param-name>com.sun.jersey.spi.container.ContainerResponseFilters</param-name>
  <param-value>com.sun.jersey.server.linking.LinkFilter</param-value>
</init-param>
