[update - example is the same but I have reworded my caveats]

[更新 - 示例是相同的但我已经重写了我的警告]

It can be done. Try the following:

可以办到。请尝试以下方法:

import com.sun.jersey.api.model.AbstractResource;
import com.sun.jersey.api.model.AbstractSubResourceMethod;
import com.sun.jersey.server.impl.modelapi.annotation.IntrospectionModeller;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

public class AnimalsTest
{
   public static void main(String [] args)
   {
      AbstractResource resource = IntrospectionModeller.createResource(AnimalResource.class);
      System.out.println("Path is " + resource.getPath().getValue());

      String uriPrefix = resource.getPath().getValue();
      for (AbstractSubResourceMethod srm :resource.getSubResourceMethods())
      {
         String uri = uriPrefix + "/" + srm.getPath().getValue();
         System.out.println(srm.getHttpMethod() + " at the path " + uri + " return " + srm.getReturnType().getName());
      }
   }
}

class Dog {}

class Cat {}

@Path("/animals")
class AnimalResource {
    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Path("dog")
    public Dog getDog(){
      return null;
    }

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Path("cat")
    public Cat getCat(){
       return null;
    }
}

These introspection classes are in jersey-server.

这些内省类在泽西服务器中。

Note that the example above uses some Jersey classes that have "impl" in the package name which suggests that these Jersey classes are not intended for public consumption and may very well have breaking changes in the future. I am just speculating here - I am not a Jersey committer. Just a random user.

请注意,上面的示例使用了一些在包名称中具有“impl”的Jersey类,这些类表明这些Jersey类不用于公共消费,并且可能在将来很有可能发生重大变化。我只是在这里推测 - 我不是泽西岛的提交者。只是一个随机的用户。

Also everything above I figured out by perusing the source code. I have never seen any documentation of an approved way to introspect JAX-RS annotated classes. I agree that an officially supported API to do this kind of thing would be very helpful.

此外,我通过仔细阅读源代码找到了所有内容。我从未见过任何关于内省JAX-RS注释类的批准方法的文档。我同意官方支持的API来做这种事情会非常有帮助。
