In this issue, Xiaobian will bring you about how to upgrade SpringBoot website to HTTPS. The article is rich in content and analyzes and narrates from a professional perspective. After reading this article, I hope you can gain something.

keytool -genkey -alias tomcat -dname "CN=Andy,OU=kfit,O=kfit,L=HaiDian,ST=BeiJing,C=CN" -storetype PKCS12 -keyalg RSA -keysize 2048 -keystore keystore.p12 -validity 365

The meaning of each parameter of the command:

-genkey: generate key;

-alias: alias of key;

-dname: Specifies certificate owner information

-storetype: Keystore type is JCEKS. JKS(default),JCEKS(recommended),PKCS12,BKS,UBER. Each keystore can be only one of these types.

-keyalg: DSA or RSA algorithm (when using-genkeypair parameter), DES or DESede or AES algorithm (when using-genseckey parameter);

-keysize: The key length is between 512 and 1024 (multiples of 64)

-keystore: Name of the certificate repository

-validity: specifies how many days the certificate created is valid

Details of dname:

CN(Common Name)

OU(Organization Unit Name)

O(Organization name)

L(Locality city or region name)

ST(State or Province)

C(Country name)

Under directory C:\Users\current user you will see a file keystore.p12

Enable HTTPS in Spring Boot

Configure HTTPS in application.properties.

#https port number

server.port=81

#http port number

http-port=82

#Path to certificate.

server.ssl.key-store=classpath:keystore.p12

#Certificate password, please change it to your own certificate password

server.ssl.key-store-password=123456

#Keystore Type

server.ssl.keyStoreType=PKCS12

#Certificate alias

server.ssl.keyAlias=tomcat
