错误：创建 SOAP 签名时“没有为签名提供加密属性文件”

Question

我正在尝试在 Java 和 Spring 中创建签名的 SOAP 消息。

我在我的

@Bean

课上创建了一个

ClientConfig

，这是内容：

    @Bean
    public CryptoFactoryBean getCryptoFactoryBeanClient() throws IOException {
        CryptoFactoryBean cryptoFactoryBean = new CryptoFactoryBean();

        Properties cryptoProperties = new Properties();
        cryptoProperties.setProperty("org.apache.ws.security.crypto.provider", "org.apache.ws.security.components.crypto.Merlin");
        cryptoProperties.setProperty("org.apache.ws.security.crypto.merlin.file", new ClassPathResource("client.jks").getPath());
        cryptoProperties.setProperty("org.apache.ws.security.crypto.merlin.keystore.type", "jks");
        cryptoProperties.setProperty("org.apache.ws.security.crypto.merlin.keystore.password", "clientkeystore");
        cryptoFactoryBean.setConfiguration(cryptoProperties);
        return cryptoFactoryBean;
    }

之前我使用以下命令从终端创建了一个 jks 文件：

keytool -genkeypair -alias clientKeyPair -keyalg RSA -keysize 2048 \ -dname "CN=localNamespace" -validity 365 -storetype JKS \ -keystore client.jks -storepass clientkeystore

和另一个名为

server.jks

的 jks 密钥库，其中包含客户端公私密钥对的公钥。

当我尝试执行这段代码时，我总是得到这个错误，我无法修复：

我了解到客户端出现错误，代码似乎无法检索私钥以签署 SOAP 消息。

有什么想法吗？

非常感谢
