Tomcat同时支持http及https

1、Tomcat同时支持http及https
2、Springboot同时支持http及https

1、Tomcat同时支持http及https

<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol" maxThreads="150" SSLEnabled="true" defaultSSLHostConfigName="michael.com">
	<SSLHostConfig hostName="tomcat9.com">
		<Certificate certificateKeystoreFile="/root/michael.keystore" certificateKeystorePassword="123456" type="RSA" />
	</SSLHostConfig>
</Connector>

注意：
tomcat8.5之后，在Connector元素中配置相关SSL属性已被废弃，应该使用<SSLHostConfig> and <Certificate>；端口8443可以直接改为https默认的443端口；
certificateKeystoreFile：需要设置自己的keystore文件路径。
certificateKeystorePassword：需要设置自己的keystore文件的密码。

2、Springboot同时支持http及https

将生成的 jks 文件放到项目的 resource 目录下，开始配置 application.yml 文件。

server:
  port: 8888
  custom:
    # http 端口
    httpPort: 9999
  ssl:
    key-store: classpath:keystore.jks
    key-password: 123456
    key-store-type: JKS
  tomcat:
    uri-encoding: utf-8
    basedir: tmp
  #
  servlet:
    context-path: /

        TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();
        tomcat.addAdditionalTomcatConnectors(createStandardConnector());
        return tomcat;
    }
    /**

     */
    private Connector createStandardConnector() {
        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setPort(httpPort);
        return connector;
    }
}
