如何排除bouncycastle weblogic 12c库

Question

我有一个Web服务，它是一个数字签名（验证pdf，签名pdf）我正在使用库bcpkix-jdk15on-1.54.jar，bcprov-jdk15on-1.54.jar，itextpdf-5.4.0.jar.和作为Weblogic 12c12.2.1.2应用服务器当我在本地测试服务时，一切正常，但当在服务器上测试时，服务返回：java.lang.ClassNotFoundException：org.bouncycastle.jcajce.provider.digest.SHA256$Digest

经核实，图书馆正在战争中。找出应用程序的bouncyCastle和weblogic bouncyCastle之间的库冲突可能是什么原因，在weblogic中添加下一行。xml

            <wls:package-name>org.bouncycastle.*</wls:package-name>
        </wls:prefer-application-packages>```

But the result is the same

Answer 1

尝试将其添加到weblogic中。xml文件：

<container-descriptor>
    <prefer-application-packages>
        <package-name>org.bouncycastle</package-name>
    </prefer-application-packages>
</container-descriptor>

Answer 2

我知道这个问题已经存在很长时间了，但我遇到了类似的问题，解决方案是使用以下选项之一将这些JARs文件放在服务器类路径上：

• 启动脚本（setUserOverrides.sh[or. bat]）
• 将它们复制到DOMAIN_HOME/lib目录

希望有帮助。
