java.net.MalformedURLException：未知协议：Spring启动升级后来自tomcat的类路径

Question

我将Spring Boot上的项目从2.0.0.M7升级到2.0.1，我的ssl配置已经破解。 我在资源目录中有我的密钥库/信任库，以及指向它们的application.yml中的属性。

application.yml

server:
  schema: "https"
  address: "localhost"
  port: 8080
  sslPort: 8443
  servlet:
    session:
      timeout: 900

spring:
  profiles:
    active: dev

ssl:
  keystoreFile: classpath:.keystore
  keystorePass: ****
  truststoreFile: classpath:.truststore
  truststorePass: ****

我使用属性在我的@Configuration类中构建ssl连接器。 这里的sslProperties对象包含来自上面的application.yml的ssl部分的所有属性。

private Connector createSslConnector(WebServerProperties webServerProperties, SslProperties sslProperties) {
    Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
    Http11NioProtocol protocol = (Http11NioProtocol) connector.getProtocolHandler();

    connector.setScheme(WebServerProperties.HTTPS_SCHEMA);
    connector.setSecure(true);
    connector.setPort(webServerProperties.getSslPort());

    protocol.setSSLEnabled(true);
    protocol.setKeystoreFile(sslProperties.getKeystoreFile());
    protocol.setKeystorePass(sslProperties.getKeystorePass());
    protocol.setKeyPass(sslProperties.getKeyPass());
    protocol.setKeyAlias(sslProperties.getKeyAlias());
    protocol.setCiphers(sslProperties.getCiphers());
    protocol.setSslEnabledProtocols(sslProperties.getSslProtocols());

    return connector;
}

升级后，应用程序不会以下面的异常开始

Spring Boot 2.0.0.M7包含tomcat-embed-core-8.5.23，其中AbstractHttp11Protocol为。 Spring Boot 2.0.1有tomcat-embed-core-8.5.29。 而较新的tomcat版本似乎忘记了如何从类路径中读取
