別のモジュールのBeanを使用する

Question

私はバッチアプリケーションを作成して、データベース上のWebサービスからのデータを入れています。 これを行うには、利用可能なクラスでWebサービスが受け取ったDTOを変換する必要があります。これは、他のモジュールで定義されたマッパーを使用して行うことができます。

マッパーに@Autowierdしようとしたときに私は例外があり、どうやって外に出るのか分かりません。

マッパーはモジュールで正常に動作しています。私はそれらを@Autowierddで問題なく使用することができます。 @autowierdマッパーを使わなければ、私のバッチは正常に動作しています。

誰かがアイデアを持っていますか？

ありがとうございます！

@Configuration 
@EnableBatchProcessing 
@ComponentScan(basePackages = {"com.execution.batch"}) 

私は入れてみました：@ComponentScan(basePackages = {"com.execution.batch", "com.execution.serve"})

しかし、私は、私はの注入に報告されたエラーを持っていることを行う場合

私の設定は、私の仕事の設定クラスにある

私が言ったように、別々のモジュールはうまく動作します。

• サーバーとバッチモジュールをスキャンすると、バッチのスキャンが機能しません。
• バッチモジュールだけをスキャンすると、私が思うにスキャンできないため、サーバーモジュールが動作しません。

Answer 1

"スキャナー"を適切なクラスのパッケージで設定するのを忘れてしまったようです。

お豆はutilisateurProcessor、fqnはcom.execution.batch.processor.UtilisateurProcessorです。 @ComponentまたはXMLで設定されていますか？

com.execution.server.common.mapperをSpringのスキャナに追加したかどうかを確認するには、スプリングの設定を貼り付けてください。

Answer 2

構成が独立して動作するため、両方のパッケージに矛盾する名前があるという良い変化があります。その結果、構成やBeanが上書きされる可能性があります。

など。

package com.x; 
@Configuration 
public class AConfiguration { 
} 

package com.y; 
@Configuration 
public class AConfiguration { 
} 

springcontextのbeannameとして、パッケージなしでクラス名のみが使用されます。つまり、両方のパッケージをスキャンすると、実際にConfiguration-Classだけが処理されます。これは@Componentで注釈が付けられたクラスに対しても有効です。

@Componentクラスと@Configurationクラスもbeannameという簡単なクラス名でBeanとしてインスタンス化されることを理解することが重要です。

また、@Beanアノテーション付きメソッドは、潜在的なエラーの原因です。異なる2つのConfiguration-Beanに同じメソッド名がある場合、インスタンス化されるのは1つだけです。

@Bean methodnameとして@Configurationクラス名と同じ名前を使用すると、もう一方がもう一方の名前で上書きされます。
