ほとんどのビジネス ロジックを含む JAR ファイルがあります。Spring MVC で開発された私の Web アプリケーションは、その JAR ファイルを使用します。JAR ファイルを保護するために、JarCryp を使用しました。JarCryp は、JAR ファイルから .sjar ファイルを作成しました。ここで、Tomcat から JAR ファイルをロードするために、Tomcat の context.ieAdded 次の行を context.xml に追加しました。

 <Loader className="ComponioSampleClassLoader" ></Loader>

ComponioSampleClassLoaderクラスがorg.apache.catalina.loader.WebappClassLoaderを拡張した場所。

今、Tomcatを起動すると、次のエラーが発生します

数時間同じ問題に苦労しました...

WebappClassLoader ではなく、WebappLoader (org.apache.catalina.loader.WebappLoader) から拡張する必要があります。

両方のコンストラクターが同じであることに気付くでしょう。そのため、この変更を行うときにコンストラクターを変更する必要はほとんどありません。

package tomcat7;

import org.apache.catalina.loader.WebappLoader;

public class Tomcat7CustomWebappLoader extends WebappLoader {

    public Tomcat7CustomWebappLoader() {
        super();
    }

    public Tomcat7CustomWebappLoader(ClassLoader parent) {
        super(parent);
    }
}

WebappLoader からの拡張は、Tomcat にパッケージ化された "VirtualWebappLoader" (org.apache.catalina.loader.VirtualWebappLoader) Loader 実装を見ても明らかです。

残念ながら、特定のユースケースの経験はありませんが、ローダーは WebappLoader を拡張する必要があります。

ここのページの下部近くにあるより高度な実装
