public class SSLServerExample {

        //該伺服器已申請SSL

        //並產出jks文件

/*

使用SSL FOR FREE

下載到三個檔案

certificate.crt

ca_bundle.crt

private.key

轉成pfx

openssl pkcs12 -export -out certificate.pfx -inkey private.key -in certificate.crt -certfile ca_bundle.crt

加密 轉成java使用的jks

keytool -importkeystore -srckeystore certificate.pfx -srcstorepass 密碼 -srcstoretype pkcs12 -destkeystore keystore.jks -deststoretype jks -deststorepass 密碼
