将 Jetty 6.1 迁移到 9.3 有多个问题
Migrating Jetty 6.1 to 9.3 has multiple issue
Hi All need few suggestion while migrating our legacy application
which has in-built jetty server 6.1.
I am trying to migrate to Jetty 9.3, yes after long gap and after
decided to move to JAVA 8. While changing few of the files I encounter
piece of code written in jetty 6.1.
Code:
@Override
public void initialize(final ServiceConfiguration genericConfig, final Controller controller, final int serviceId,
final ServiceLock lock) throws Exception {
if (genericConfig instanceof JettyServerConfiguration) {
configuration = (JettyServerConfiguration) genericConfig;
} else {
configuration = XmlConfigurable.createInstance(JettyServerConfiguration.class,
genericConfig.getXmlConfigElement());
}
server = new Server();
log.info("jetty version = " + Server.getVersion()); //frozen
maxWaitForSlave = getConfiguration().getMaxWaitForSlave();
final boolean debug = getConfiguration().getMortBayDebug();
log.info("mortbay debug = '" + debug + "'"); //frozen
org.mortbay.log.Log.getLog().setDebugEnabled(debug);
// Configure http
final boolean httpEnabled = getConfiguration().getHttpEnabled();
if (httpEnabled) {
// Setup http connector as nio or socket.
final boolean nio = getConfiguration().getNioEnabled();
Connector connector;
if (nio) {
connector = new SelectChannelConnector();
} else {
connector = new SocketConnector();
}
final int mainPort = getConfiguration().getHttpPort();
log.info("adding default connector on port '" + mainPort + "'"); //frozen
connector.setPort(mainPort);
server.addConnector(connector);
}
// Configure SSL
final boolean sslEnabled = getConfiguration().getSslEnabled();
if (sslEnabled) {
final int sslPort = getConfiguration().getSslPort();
final String sslKeyStore = getConfiguration().getSslKeyStore();
final String sslPassword = getConfiguration().getSslPassword();
final String sslKeyPassword = getConfiguration().getSslKeyPassword();
final String sslTrustPassword = getConfiguration().getSslTrustPassword();
//final boolean nio = configuration.getBooleanValue("NioEnabled", false); //frozen
//if(nio) {
//sslConnector = new SslSelectChannelConnector(); available in jetty 7
//} else {
final SslSocketConnector sslConnector = new SslSocketConnector();
sslConnector.setKeystore(sslKeyStore);
sslConnector.setTruststore(sslKeyStore);
sslConnector.setPassword(sslPassword);
sslConnector.setKeyPassword(sslKeyPassword);
sslConnector.setTrustPassword(sslTrustPassword);
sslConnector.setPort(sslPort);
log.info("adding ssl connector on port '" + sslPort + "'"); //frozen
server.addConnector(sslConnector);
//}
}
// Check we had 1 connector else the server is useless
if (server.getConnectors().length == 0) {
throw new FileNotFoundException("No connectors registered. Please see HttpEnable or SslEnable XML tags."); //frozen
}
// Configure the handlers
final HandlerCollection handlers = new HandlerCollection();
for (final WebAppContext webAppContext : getConfiguration().getWebAppContexts()) {
log.info("Adding WebAppContext " + webAppContext.getWar() + " at " + webAppContext.getContextPath()); //frozen
handlers.addHandler(webAppContext);
}
// See http://docs.codehaus.org/display/JETTY/Logging+Requests
final boolean accessLogEnabled = getConfiguration().getLogEnabled();
if (accessLogEnabled) {
final RequestLogHandler requestLogHandler = new RequestLogHandler();
final File logDir = ServiceUtilities.getLogDirectory();
if (!logDir.exists()) {
logDir.mkdirs();
}
final File logFile = new File(getConfiguration().getLogFormat());
if (!logFile.getParentFile().exists()) {
logFile.getParentFile().mkdirs();
}
final NCSARequestLog requestLog = new NCSARequestLog(getConfiguration().getLogFormat());
requestLog.setRetainDays(getConfiguration().getLogRetain());
requestLog.setAppend(getConfiguration().getLogAppend());
requestLog.setExtended(getConfiguration().getLogExtended());
requestLog.setLogTimeZone(getConfiguration().getLogTz());
requestLog.setLogLatency(getConfiguration().getLogLatency());
requestLogHandler.setRequestLog(requestLog);
handlers.addHandler(requestLogHandler);
}
handlers.addHandler(new DefaultHandler());
server.setHandler(handlers);
server.setUserRealms(new UserRealm[] { new OSMUserRealm() });
JettyServerInfo.install(server);
super.initialize(configuration, controller, serviceId, lock);
}
After the suggestion given below , I have re-written it like:
@Override
public void initialize(final ServiceConfiguration genericConfig, final Controller controller, final int serviceId,
final ServiceLock lock) throws Exception {
if (genericConfig instanceof JettyServerConfiguration) {
configuration = (JettyServerConfiguration) genericConfig;
} else {

//Re-writing code for Jetty 9.3

final String sslKeyPassword = getConfiguration().getSslKeyPassword();
final String sslTrustPassword = getConfiguration().getSslTrustPassword();
//Added for Jetty 9.3
final KeyStore trustKeyStore=KeyStore.getInstance(getConfiguration().getSslKeyStore());
ClassLoader cl = JettyServer.class.getClassLoader();// Get the class loader for my current class which is JettyServer
String keystoreResource = "ssl/keystore";

{
throw new RuntimeException("Unable to find " + keystoreResource);
}
// Setup HTTP Connector

theSSLFactory.setTrustStore(trustKeyStore);
theSSLFactory.setTrustStorePassword(sslTrustPassword);
// Setup HTTPS Configuration
HttpConfiguration httpsConf = new HttpConfiguration(httpConf);
httpsConf.addCustomizer(new SecureRequestCustomizer()); // adds ssl info to request object
// Establish the HTTPS ServerConnector
ServerConnector httpsConnector = new ServerConnector(server,
new SslConnectionFactory(theSSLFactory,"http/1.1"),
new HttpConnectionFactory(httpsConf));
httpsConnector.setPort(sslPort);
log.info("adding ssl connector on port '" + sslPort + "'"); //frozen
server.addConnector(httpsConnector);
// Check we had 1 connector else the server is useless
if (server.getConnectors().length == 0) {
throw new FileNotFoundException("No connectors registered. Please see HttpEnable or SslEnable XML tags."); //frozen
}
// Configure the handlers
final HandlerCollection handlers = new HandlerCollection();
for (final WebAppContext webAppContext : getConfiguration().getWebAppContexts()) {
log.info("Adding WebAppContext " + webAppContext.getWar() + " at " + webAppContext.getContextPath()); //frozen
handlers.addHandler(webAppContext);
}
// See http://docs.codehaus.org/display/JETTY/Logging+Requests
final boolean accessLogEnabled = getConfiguration().getLogEnabled();
if (accessLogEnabled) {
final RequestLogHandler requestLogHandler = new RequestLogHandler();
final File logDir = ServiceUtilities.getLogDirectory();
if (!logDir.exists()) {
logDir.mkdirs();
}
final File logFile = new File(getConfiguration().getLogFormat());

}
handlers.addHandler(new DefaultHandler());
server.setHandler(handlers);
server.setUserRealms(new UserRealm[] { new OSMUserRealm() });
JettyServerInfo.install(server);
super.initialize(configuration, controller, serviceId, lock);
}
Still I am not sure what to do with this line.
server.setUserRealms(new UserRealm[] { new OSMUserRealm() });
I didn't find any alternative method in jetty 9.3 for UserRealm, any
suggestion how can I re-write this line of code?
Reminder: Jetty versioning (since 1995) is <servlet_support>.<major_version>.<minor_version>
恭喜，您实际上已经跳过了 Jetty 中的 14 个主要版本。 :-)
难怪看起来这么吓人。
decided to move to JAVA 8
知道January 2019 is the last day of Java 8 public updates。
对于非付费的 Oracle 客户来说，这实际上是生命的终结。
注意：Java9 已被弃用/不受支持。
由于您提到使用 SSL/TLS，因此 必须使您的 JVM 保持最新并且 not use an expired JVM（浏览器要求和 TLS 要求）。
考虑在今年 (2018) 结束之前（再次）升级到 Java 11。
java 的更新周期正在加快，不要指望 Java 版本会持续多年。预计主要版本不会持续超过 6 个月（目前）。
log.info("mortbay debug = '" + debug + "'"); //frozen
org.eclipse.jetty.util.log.Log.getLog().setDebugEnabled(debug);
日志记录不是这样工作的。
这取决于选择的实现（现在有 SLf4j、java.util.logging 和 System.err）。使用 Log.getLog() 可以获得根日志外观，而在外观上使用 setDebugEnabled() 只是在外观上设置调试，而不是实际的记录器。
使用正确的日志记录实现和命名记录器。
if (nio) {
connector = new SelectChannelConnector(server);
} else {
connector = new SocketConnector(server);
}
不再有阻塞连接器，它 100% 基于 NIO（对于过去的 5 个主要版本）
欢迎来到现代网络协议的世界。
连接器仅服务于 1 种协议的日子已经一去不复返了，现在所有协议都在实际连接期间协商。
例如：Connect, TLS, ALPN, HTTP/2, HTTP/1.1 with TLS, HTTP/1.1 without TLS, etc.单个连接的 TLS 协商也用于确定您与哪个 webapp 交谈，使用什么主机，以及什么证书等）
ServerConnector 的作用是只监听一个端口，您分配给 ServerConnector 的 ConnectionFactories 决定如何处理该连接。
为此阅读各种示例代码。

server.setHandler(new HelloHandler("Hello Secure World"));
server.start();
server.join();
}
server.setUserRealms(new UserRealm[] { new OSMUserRealm() });
I didn't find any alternative method in jetty 9.3 for UserRealm, any suggestion how can I re-write this line of code?
安全由 LoginService 处理，一个 LoginService 可以拥有一个领域（如果该 LoginService 支持这样的概念）。
LoginService 可以作为服务器上的 Bean，但这只是为了控制 LoginService 的生命周期。
具有安全上下文设置以使用特定领域的 WebAppContext 将查找服务器上的所有 LoginService bean 并使用与指定领域匹配的那个。
