springboot soap请求中的URLResource

Question

我正在使用spring boot来对证书进行数字签名。这是我的代码段。

@Bean
public Wss4jSecurityInterceptor securityInterceptor() throws Exception {
    Wss4jSecurityInterceptor securityInterceptor = new Wss4jSecurityInterceptor();
    // set security actions
    securityInterceptor.setSecurementActions("Timestamp Signature");
    // sign the request
    securityInterceptor.setSecurementPassword("password");
    securityInterceptor.setSecurementSignatureCrypto(getCryptoFactoryBean().getObject());
    securityInterceptor.setSecurementSignatureKeyIdentifier("DirectReference");

    return securityInterceptor;
}

@Bean
public CryptoFactoryBean getCryptoFactoryBean() throws IOException {
    CryptoFactoryBean cryptoFactoryBean = new CryptoFactoryBean();
    cryptoFactoryBean.setKeyStorePassword("password");
    cryptoFactoryBean.setKeyStoreLocation(new UrlResource("http://hostname/cert.p12"));
    return cryptoFactoryBean;
}

我收到以下错误：

Caused by: java.io.FileNotFoundException: URL [http://hostname/cert.p12] cannot be resolved to absolute file path because it does not reside in the file system: http://hostname/cert.p12 at org.springframework.util.ResourceUtils.getFile(ResourceUtils.java:215) at org.springframework.core.io.AbstractFileResolvingResource.getFile(AbstractFileResolvingResource.java:53) at org.springframework.core.io.UrlResource.getFile(UrlResource.java:213) at org.springframework.ws.soap.security.wss4j2.support.CryptoFactoryBean.getResourcePath(CryptoFactoryBean.java:91)

有没有办法在cryptoFactoryBean.setKeyStoreLocation中使用URL？

谢谢，
