我正在使用WSS4J使用来自密钥库的证书创建一个肥皂请求签名者。我的密钥库格式是 .pkcs 并且在第一次签名时一切正常，但是如果我尝试运行程序来签署多个文档并且它在密钥库中找不到证书。在我看来，证书可能在签名期间被消耗，这意味着它不再存在于当前环境中。如果程序停止并重新启动，它将签署第一个请求，但第二个请求失败。我经历了多次，无法弄清楚原因是什么。此代码是证书从密钥库中消失之前调用的最后一件事，this.certUri = getWsConfig().getIdAllocator().createSecureId("X509-", certs[0]);可在第 556 行找到WSSecSignature.class。这是我的代码。

另外，我想在中打开 doDebug 模式，WSSecBase.class但它不会显示在变量查看器中来切换值。我在构造函数中创建了一个断点并将其设置为被监视，但它从未显示为切换。
