JFinal本事内置的jetty8已经基本满足开发需求。由于本人是版本控,同时想在某些小型项目中直接用内置的jetty运行。
于是将内置的jetty升级到9.由于jetty9盒jetty8变化很大。所以几乎需要重写com.jfinal.server.JettyServer的doStart方法。需要引入jetty9的jar包。
最新的Jetty 9.3.0.v20150612 最低要求java8

为了支持ssl还得修改com.jfinal.core.JFinal实现,增加相应的方法。
public static void startSSLServer(String webAppDir, int port, String context, String keyStorePath,String keyStorePassword,String keyManagerPassword) { server = ServerFactory.getHttpsServer(webAppDir, port, context, keyStorePath, keyStorePassword, keyManagerPassword); server.start(); }
