java.lang.AbstractMethodError：org.slf4j.impl.Log4jLoggerAdapter.log（ava/lang /オブジェクト; Ljava/lang/Throwable;）V

Question

私はsamll Camelアプリケーションを実行しようとしていますが、log4j関連のエラーが発生しています。多くのフォーラムで、残念ながら使用していません。私はこれを解決するために手伝ってください。事前にありがとうございます。

Gradleの依存関係：

+--- org.slf4j:slf4j-api:1.7.6 
| | \--- org.slf4j:jcl-over-slf4j:1.7.6 
| |   \--- org.slf4j:slf4j-api:1.7.6 

のlog4j関連の依存関係：

compile group: 'org.slf4j', name: 'jcl-over-slf4j', version:'1.5.8' 
    compile group: 'org.slf4j', name: 'slf4j-api', version:'1.5.8'

    compile group: 'log4j', name: 'log4j', version:'1.2.14'

Answer 1

SLF4JのAPIバージョンとそのバインディングバージョンは互換性があります（一般的には同じバージョン）。実行時に

は、SLF4Jが使用されるバインディング1.5.8ですが、ロードされたSLF4J APIは1.6/1.7であるバージョン：

SLF4J: The requested version 1.5.8 by your slf4j binding is not compatible with [1.6, 1.7]

あなたはおそらく1.6/1.7 APIのバージョンを引っ張る推移依存関係を持っていますSLF4J。
実行時に使用されるクラスパスでこのjarを指定することもできます。 両方を確認してください。

Gradleプロジェクトの依存関係を確認するには、gradle app:dependenciesを使用して、gradleプロジェクトの依存関係のツリーを取得します。
