java - 如何为相互 SSL 覆盖 Spring Boot 密钥库/信任库

问题描述

我有一个 Spring Boot 应用程序。它的 application.yml 是从在线资源中获取的。它包含以下用于相互 SSL 的配置：

server:
  ssl:
    enabled: true
    client-auth: need
    key-store-type: PKCS12
    key-store: http://{config server url}/keystore.p12
    key-store-password: {keystore password}
    trust-store-type: JKS
    trust-store: http://{config server url}/truststore.jks
    trust-store-password: {truststore password}
  port: 8443

运行应用程序时，出现此错误：

java.io.IOException: DerInputStream.getLength(): lengthTag=111, too big.
    at sun.security.util.DerInputStream.getLength(DerInputStream.java:599)
    at sun.security.util.DerValue.init(DerValue.java:391)

    at org.apache.tomcat.util.net.SSLUtilBase.getKeyManagers(SSLUtilBase.java:272)

    at org.apache.tomcat.util.net.AbstractJsseEndpoint.createSSLContext(AbstractJsseEndpoint.java:97)
    ... 23 common frames omitted

但是我可以通过以编程方式打开密钥库和信任库。（如下图）

private KeyStore getKeyStore() {
    KeyStore keyStore = KeyStore.getInstance("PKCS12");
    try (InputStream is = readCertificateFromURL(new URI(keyStoreURL))) {
        keyStore.load(is, keyStorePassword.toCharArray());
    }
    return keyStore();
}

private InputStream readCertificateFromURL(URI uri) throws IOException {
    RequestEntity<Void> requestEntity = RequestEntity.get(uri)
         .accept(org.springframework.http.MediaType.APPLICATION_OCTET_STREAM)
         .build();
    Resource resource = new RestTemplate().exchange(requestEntity,Resource.class).getBody();
    return resource.getInputStream();
}

我如何告诉 Spring boot 选择这些密钥/信任库而不是 application.yml 中定义的那些？

我在网上找到的唯一内容是关于覆盖密钥库/信任库路径，而不是 KeyStore 对象本身。

解决方案

Spring 属性中 和 的值javax.net.ssl.trustStore及其javax.net.ssl.keyStore对应的值需要是文件系统路径。如果您将它们复制到本地文件系统并引用它们，您的方法是否有效？
