Question

如何在泽西时使用restlet使用accept header字段对REST api进行版本控制：

// Jersey
@GET
@Path("test")
@Produces("application/myapp.v1+json;charset=utf-8")
public pojo.v1.PersonPoJo testV1()
{
  return new pojo.v1.PersonPoJo("Smith", "Jeff", 34);
}

@GET
@Path("test")
@Produces("application/myapp.v2+json;charset=utf-8")
public pojo.v2.PersonPoJo testV2()
{
  return new pojo.v2.PersonPoJo("Smith", "Jeff", 34, "j.smith@rest.com");
}


// Restlet
@GET("json")
public pojo.PersonPoJo test()
{
  return new pojo.PersonPoJo("Smith", "Jeff", 34);
}

为此，您需要为两个版本定义自定义扩展。这可以在您的申请中完成：

public class MyApplication extends Application {
    public MyApplication() {
        getMetadataService().addExtension(
            "myapp.v1", new MediaType("application/myapp.v1+json"));
        getMetadataService().addExtension(
            "myapp.v2", new MediaType("application/myapp.v2+json"));
        (...)
    }

    @Override
    public Restlet createInboundRoot() {
        (...)
    }
}

然后，您可以直接在服务器资源的注释中使用这些扩展：

@Get("myapp.v1")
public pojo.v1.PersonPoJo testV1()
{
  return new pojo.v1.PersonPoJo("Smith", "Jeff", 34);
}

@Get("myapp.v2")
public pojo.v2.PersonPoJo testV2()
{
  return new pojo.v2.PersonPoJo("Smith", "Jeff", 34, "j.smith@rest.com");
}
