、私のjarファイルは、次のとおりです。春3つのjarファイル+共通ロギング+ aopppliance

私は大いにthankfullになります任意のヘルプのため

Answer 1

スタックトレースには、クラスパスからorg.aspectj.weaver.reflect.ReflectionWorldがありません。これはバージョンによっては、AspectJ JARのaspectjweaver.jarまたはaspectjtools.jarのいずれかにあります。

Answer 2

一部の依存関係がありません。 あなたはMavenを使用している場合は、それらの依存関係を追加：

<dependency> 
     <groupId>org.aspectj</groupId> 
     <artifactId>aspectjtools</artifactId> 
     <version>1.6.2</version> 
    </dependency> 

    <dependency> 
     <groupId>cglib</groupId> 
     <artifactId>cglib</artifactId> 
     <version>2.2</version> 
    </dependency> 

そうでない場合は、単に必要なjarファイルをダウンロードして、あなたのクラスパスに追加します。

Answer 3

各pojoのインターフェイスを公開する場合、Cglibは必要ありません。
