私はREST WebサービスでWebApplicationを構築しようとしており、すでにいくつかの問題に成功しました。しかし、私はこれまでこれを解決できませんでした。RESTジャージーjson NoSuchFieldError：WADLとIllegalStateException

私はTomCat v7.0ローカルホストを使用していて、簡単な@GETリソースにアクセスしようとしています。私は、リソースをクリックしたときには、以下のエラーが表示されます。

A MultiException has 2 exceptions. They are: 
1. java.lang.NoSuchFieldError: WADL 
2. java.lang.IllegalStateException: Unable to perform operation: create on org.glassfish.jersey.server.wadl.processor.WadlModelProcessor

私はstackoverflowのを検索し、私はこれを開始（2016年4月に尋ねた）多分、同一の問題で質問が、ありませんソリューション

を発見しました。 eclipseネオンでMavenプロジェクトとしてプロジェクト。ここで

シンプルなREST Testクラス：

package data.controller; 

import javax.ws.rs.GET; 
import javax.ws.rs.Path; 
import javax.ws.rs.PathParam; 
import javax.ws.rs.core.Response; 

@Path("/test") 
public class RESTTest { 

    @GET 
    public Response getString() { 
     return Response.status(200).entity("getString is called").build(); 
    } 
}

、そして最後にスタックトレース：

私は問題がいくつかのLIBSによって引き起こされるかもしれないと思うが、私はよく分かりませんいくつかの変更がこの問題を解決していませんでした。

私は各回答に感謝しています。私が何かを忘れた場合は、お気軽にお問い合わせください。 は、私はあなたが@RequestMapping注釈を欠場持っていると思う

例えば

@RequestMapping(value="/methodName", method=RequestMethod.GET) 
    public Response getString() { 
     return Response.status(200).entity("getString is called").build();

こんにちはvaibhav patil、私はそれを試みましたが、成功しませんでした。資源のより簡単な方法 "（@GET） \tパブリック文字列のgetString（）{ \t \tリターン "こんにちは"; \t}" 達人例等は、didntの仕事を与えます。 –
