如何使用Jersey在Android应用程序中托管Rest API服务器？

implementation 'org.glassfish.jersey.core:jersey-server:2.34'
implementation 'org.glassfish.jersey.containers:jersey-container-servlet:2.34'

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

@Path("/example")
public class ExampleResource {

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String getExample() {
        return "Hello, Jersey!";
    }
}

<servlet>
    <servlet-name>JerseyServlet</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>com.example.resources</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>JerseyServlet</servlet-name>
    <url-pattern>/api/*</url-pattern>
</servlet-mapping>

import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.servlet.ServletContextHandler;
import org.eclipse.jetty.servlet.ServletHolder;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Create Jetty server
        Server server = new Server(8080);

        // Create Servlet context handler
        ServletContextHandler contextHandler = new ServletContextHandler();
        contextHandler.setContextPath("/");
        server.setHandler(contextHandler);

        // Add Jersey Servlet
        ServletHolder jerseyServlet = contextHandler.addServlet(ServletContainer.class, "/*");
        jerseyServlet.setInitOrder(0);
        jerseyServlet.setInitParameter("jersey.config.server.provider.packages", "com.example.resources");

        try {
            // Start the server
            server.start();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
