BeanInstantiationExceptionが原因でBeanInstantiationExceptionが発生しました：名前

現在、Webアプリケーションをテストしようとしていますが、BeanInstantiationExceptionおよびBeanCreationExceptionの原因となるWebsphere 8.5を起動しようとすると、NullPointerExceptionが発生し続けます。 mvc-dispatcher-servlet.xmlファイルでアノテーションを使い、Beanを削除しようとしましたが、同じエラーが発生したままですが、別のBeanを使用しています。私はこれを実行するために私が何を変える必要があるのか分からない。BeanInstantiationExceptionが原因でBeanInstantiationExceptionが発生しました：名前

SecurityClient Beanはセキュリティクライアント0.jarと呼ばれる瓶から来ています。どんな提案もありがとう

と

使用この

@Autowired private SessionBean session; @Autowired private RacfGroupData racfGroup;

SecurityService.classでリファクタリングこのライン

private JacksonDecoder _decoder = new JacksonDecoder(); private SecurityServiceApi _securityServiceApi = Feign.builder() .decoder(_decoder) .encoder(new JacksonEncoder()) .target(SecurityServiceApi.class, System.getProperty("securityServicesBaseUrl"));

？ – 11thdimension

EDIT：エラーログを追加するのを忘れました。 – Karson074

例外は 'SecurityService'クラスから来ています。そのためのコードを追加する必要があります。 SecurityServiceのコンストラクタにNPEを設定せずに投げるオブジェクトがあります。また@kakashiのハタケが指摘したように、コントローラメソッドが呼び出されたときにNPEを投げるので、 'MainController'に' ReacfGroupData'をautowireする必要があります。しかし、現在の例外は、SecurityServiceが適切に初期化されていないためです。 – 11thdimension

MainController.javaprivate RacfGroupData racfGroup;あなたはAutowired両方の豆のために必要があります。あなたはNPEを取得しているこの

@Autowired 
private JacksonDecoder _decoder; 

private SecurityServiceApi _securityServiceApi; 

@PostConstruct 
public void init() { 
_securityServiceApi = Feign.builder() 
     .decoder(_decoder) 
     .encoder(new JacksonEncoder()) 
     .target(SecurityServiceApi.class, System.getProperty("securityServicesBaseUrl")); 
}

あなたの提案通りにしましたが、私はまだ同じエラーが発生しています。 – Karson074

また、SecurityService.classにデフォルトのコンストラクタを追加します.RacfGroupData.classを追加します。また、SecurityService.classに@Autowired依存関係を設定します。 –

あなたは何を意味するのかよくわかりません。私はクラスをインスタンス化するためにSpring Beanを使用するのが初めてです。 SecurityServiceは、自分のプロジェクトにインポートしていて、Beanを使ってアクセスしようとしているjarです。コンストラクタはどこに追加すればよいですか？ – Karson074
