同じパス名（文字列）を持つ同じ @Path アノテーションがあるため、同じエラーに直面しました。

@Path('samepath')   /// samepath cause Jersey Error at run time.
/* Method 1*/

@Path('samepath')
/* Method 2 */

パラメータ@FormParamで（を期待する@POST）を使用すると、まったく同じエラーが発生しました。@GET

見つけるのがあまり直感的ではなかったので、誰かの助けになることを願っています。

web.xmlを次のコードに置き換えます。

<servlet>
    <servlet-name>Jersey Web Application</servlet-name>
    <servlet-class>  org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Jersey Web Application</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

クラスにパラメーターコンストラクターがなかったため、この問題に遭遇しました

@Path("/deviceconfigs")
public class DeviceConfigInterface extends ComInterfaceGen<DeviceConfigApi> {
    public DeviceConfigInterface(Class<DeviceConfigApi> type) {
        super(DeviceConfigApi.class);
    }
}.

パラメータコンストラクタを使用しなかった場合、問題は解決しました。
