SpringBoot配置https

#https 
//使用keytool生成本地证书 ,keytool是jdk自带的生成key工具，别名为tomcat
keytool -genkey -alias tomcat -storetype PKCS12 -keyalg RSA -keysize 2048 -keystore keystore.p12 -validity 3650
#-----上面那段话直接执行就行，Windows进去jdk目录底下。
#application.properties
#配置https
server.port=8443
#.keystore放在了src/main/resources里面，默认是隐藏的，可以从盘符下看
server.ssl.key-store=classpath:keystore.p12
#用jdk生成key时的口令
server.ssl.key-store-password=123456
server.ssl.keyStoreType:PKCS12
#key的别名
server.ssl.keyAlias:tomcat
#配置从定向
#以下就是配置重定向的代码
