java - 在 Embedded Apache Tomcat 9 中启用 SSL 并以编程方式添加证书

Question

我有以下代码来启动我的软件:

public static void main(String[] args) throws Exception {
    // set system property for exit on failure
    System.setProperty("org.apache.catalina.startup.EXIT_ON_INIT_FAILURE", "true");

    // create tomcat
    Tomcat tomcat = new Tomcat();

    // create connector, configure and add to tomcat
    Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
    connector.setMaxPostSize(-1);
    connector.setPort(8080);
    connector.setURIEncoding("UTF-8");
    ((Http11NioProtocol)connector.getProtocolHandler()).setConnectionUploadTimeout(36000000);
    ((Http11NioProtocol)connector.getProtocolHandler()).setDisableUploadTimeout(false);
    ((Http11NioProtocol)connector.getProtocolHandler()).setConnectionTimeout(3600000);
    ((Http11NioProtocol)connector.getProtocolHandler()).setCompression("on");
    ((Http11NioProtocol)connector.getProtocolHandler()).setCompressibleMimeType("text/html,text/xml,text/plain,application/javascript");
    tomcat.setConnector(connector);

    // add web app with jsps and servlets
    StandardContext standardContext = (StandardContext)tomcat.addWebapp("", new File(".").getAbsolutePath()+"/src/webroot");
    standardContext.getJarScanner().setJarScanFilter(new JarScanFilter() { @Override public boolean check(JarScanType jarScanType, String s) {
        if(s != null){
            if(s.startsWith("mchange-commons-java")){
                return false;
            }
        }

        return true;
    }});
    standardContext.setParentClassLoader(Run.class.getClassLoader());
    WebResourceRoot webResourceRoot = new StandardRoot(standardContext);
    File additionWebInfClassesFolder = new File(new File(".").getAbsolutePath(), "target/classes");
    WebResourceSet webResourceSet = new DirResourceSet(webResourceRoot, "/WEB-INF/classes", additionWebInfClassesFolder.getAbsolutePath(), "/");
    webResourceRoot.addPreResources(webResourceSet);
    standardContext.setResources(webResourceRoot);

    // start tomcat
    tomcat.start();

    // stay in this method as long as tomcat is running
    tomcat.getServer().await();
}

现在我有了我的证书文件(私钥、证书)，我想向这个 Tomcat 服务器添加 SSL 功能。我知道这可能不是最佳实践，但我正在寻找一种非常简单的方法来做到这一点。我知道我可以创建一个 keystore 文件并将属性添加到连接器，但我基本上想要的是有一个包含我的证书内容的字符串并应用它。

我的解决方案最终看起来很像我最终在这里偶然发现的代码，以帮助我解决问题:https://github.com/OryxProject/oryx/blob/master/framework/oryx-lambda-serving/src/main/java/com/cloudera/oryx/lambda/serving/ServingLayer.java#L202

注意:我相信我使用的是 Tomcat 10。

    private Connector createSslConnector(){
       Connector httpsConnector = new Connector();
       httpsConnector.setPort(443);
       httpsConnector.setSecure(true);
       httpsConnector.setScheme("https");
       httpsConnector.setAttribute("SSLEnabled", "true");

       SSLHostConfig sslConfig = new SSLHostConfig();

       SSLHostConfigCertificate certConfig = new SSLHostConfigCertificate(sslConfig, SSLHostConfigCertificate.Type.RSA);
       certConfig.setCertificateKeystoreFile("/root/.keystore");
       certConfig.setCertificateKeystorePassword("changeit");
       certConfig.setCertificateKeyAlias("mykeyalias");
       sslConfig.addCertificate(certConfig);

       httpsConnector.addSslHostConfig(sslConfig);

       return httpsConnector;
}
