如何使jersey servlet在java REST应用程序中加载多个服务或类

@Path("/users")
public class UserResource {
    // 用户相关的操作
}

@Path("/products")
public class ProductResource {
    // 产品相关的操作
}

public class MyApplication extends Application {
    @Override
    public Set<Class<?>> getClasses() {
        Set<Class<?>> classes = new HashSet<>();
        classes.add(UserResource.class);
        classes.add(ProductResource.class);
        return classes;
    }
}

<servlet>
    <servlet-name>JerseyServlet</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>com.example.MyApplication</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>JerseyServlet</servlet-name>
    <url-pattern>/api/*</url-pattern>
</servlet-mapping>
