java - 升级Spring Boot版本1.5.19后，嵌入式tomcat无法启动，原因是端口可能已在使用中或连接器配置错误

Question

将Spring Boot升级到1.5.19后，无法启动嵌入式Tomcat，并出现以下错误。


  错误：-配置为侦听端口8443的Tomcat连接器失败
  开始。该端口可能已在使用中，或者连接器可能已在使用中
  配置错误。


我已经升级到以下版本。

springBootVersion = '1.5.19.RELEASE'
springVersion = '4.3.22.RELEASE'
jerseyVersion = '1.17'
springDataJpaVersion = '1.5.19.RELEASE'
tomcatVersion = '8.5.37'

启动tomcat时，即使端口未使用，我也收到错误消息，而且我尝试使用其他端口，因此多数情况是由于配置错误所致。

我也尝试过用pkcs12代替jks。

以下是我的嵌入式tomcat ssl配置-

    Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
            Http11NioProtocol protocol = (Http11NioProtocol) connector.getProtocolHandler();
            try {
                File keystore = getFile(getKeystore());
                File truststore = keystore;
                connector.setScheme("https");
                connector.setSecure(true);
                connector.setPort(getHTTPSPort());
                //connector.setXpoweredBy(false);

                //protocol.setKeystoreType("PKCS12");
                protocol.setSSLEnabled(true);
                protocol.setKeystoreFile(keystore.getAbsolutePath());
                protocol.setKeystorePass(getKeystorePass());
                protocol.setTruststoreFile(truststore.getAbsolutePath());
                protocol.setTruststorePass(getKeystorePass());
                //protocol.setKeyAlias("tomcat");
                return connector;
            } catch (IOException ex) {
                throw new IllegalStateException("can't access keystore: [" + "keystore" + "] or truststore: [" + "keystore" + "]", ex);
            }

描述：

配置为侦听端口8443的Tomcat连接器无法启动。该端口可能已在使用中，或者连接器配置错误。

如果我手动启动tomcat并部署我的代码，则该代码可以正常工作，
问题仅在我尝试启动嵌入式tomcat时出现。

我在spring-boot-2.1.6中遇到了同样的问题。最终的解决方案是什么？
