问题描述
我们的应用程序的Spring Boot从1.5升级到2.3，突然在mvn spring-boot:run上出现以下错误：

我没有Tomcat方面的专业知识，并且在长时间的互联网搜索后无法找到解决方案。我的SSL配置看起来不错，因为它已经在一周前与Spring Boot 1.5一起使用，但是无法运行升级版本，即Spring Boot 2.3。
EDIT:这是我的SSL配置，假设所有变量都是从相应的application.yaml文件中注入的：
@Bean
public WebServerFactory servletContainer() {
final TomcatServletWebServerFactory httpFactory = new TomcatServletWebServerFactory() {
@Override
protected void customizeConnector(Connector connector) {
super.customizeConnector(connector);
connector.setPort(port);
connector.setSecure(true);
connector.setScheme("https");
final Http11NioProtocol proto = (Http11NioProtocol) connector.getProtocolHandler();
proto.setSSLEnabled(true);
proto.setKeystoreFile(keyStore);
proto.setKeystorePass(keyStorePassword);
proto.setKeystoreType("JKS");
proto.setKeyAlias(keyAlias);
}
};
final Connector httpConnector = new Connector(TomcatServletWebServerFactory.DEFAULT_PROTOCOL);
httpConnector.setPort(httpPort);
httpFactory.addAdditionalTomcatConnectors(httpConnector);
return httpFactory;
}
