HttpServer和HttpsServer简单实现

javaSE本身自己就实现了web功能，分别有两种实现一种是HTTP、HTTPS，实现类分别为HttpServer和HttpsServer但是都要自己实现HttpHandler，而且HTTPS的实现要麻烦一些需要创建证书。创建证书的工具java的bin目录下有名字叫keytool创建方法入下：

Java代码  

1. import java.io.FileInputStream;  
2. import java.io.IOException;  
3. import java.io.InputStream;

35.         KeyStore ks = KeyStore.getInstance("JKS");   //建立证书库
