什么是https

之前我在这篇文章里头说过了https

造公钥和私钥

keytool -genkey -alias sitename -keyalg RSA -keystore keystore.jks -keysize 2048

这个文件是一个公钥和私钥对

创建Connector

这一点很关键，说白了，就是当发生http请求的时候，返回一个！403，告诉他不安全，让他重定向到安全的端口

具体的做法：

1. 对于不安全的请求返回！403

其实这个是加到web.xml里头的，只是这里用代码展现出来

ConstraintSecurityHandler security = new ConstraintSecurityHandler();
Constraint constraint = new Constraint();
constraint.setDataConstraint(Constraint.DC_CONFIDENTIAL);

//makes the constraint apply to all uri paths
ConstraintMapping mapping = new ConstraintMapping();
mapping.setPathSpec("/*");
mapping.setConstraint(constraint);
security.addConstraintMapping(mapping);

// Web app handlers
WebAppContext app = new WebAppContext(server, base, "/");
app.setHandler(security);

1. 对于http的Connector，告诉它安全的端口和协议是什么

   private static ServerConnector getHttpConnector(int port) {
   HttpConfiguration config = new HttpConfiguration();
   config.setSecureScheme("https");
   config.setSecurePort(port + 443);
   ServerConnector connector = new ServerConnector(server, new HttpConnectionFactory(config));
   connector.setPort(port);
   return connector;
   }

2. 加入https的Connector

   private static ServerConnector getHttpsConnector(int port) {
   HttpConfiguration https = new HttpConfiguration();
   https.setSecurePort(port);
   https.setSecureScheme("https");
   https.addCustomizer(new SecureRequestCustomizer());
   
   SslContextFactory sslContextFactory = new SslContextFactory();
   sslContextFactory.setKeyStorePath(ControllerWebServer.class.getResource(
           "/keystore.jks").toExternalForm());
   sslContextFactory.setKeyStorePassword("123456");
   sslContextFactory.setKeyManagerPassword("123456");
   
   ServerConnector sslConnector = new ServerConnector(server,
           new SslConnectionFactory(sslContextFactory, "http/1.1"),
           new HttpConnectionFactory(https));
   sslConnector.setPort(port);
   
   return sslConnector;
   }

3. server 启动

server.setConnectors(new Connector[]{httpsConnector, httpConnector});

// Web app handlers
WebAppContext app = new WebAppContext(server, base, "/");
app.setHandler(security);

// Start app
server.start();
logger.info(LoggerServer.CU, "Start updater web server success");
server.join();
