How to configure ssl in Springboot, in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

SSL (Secure Sockets Layer secure socket layer) is a security protocol that provides security and data integrity for network communication. SSL encrypts the network connection at the network transport layer, and the SSL protocol is located between the TCP/IP protocol and various application layer protocols to provide security support for data communication. SSL protocol is divided into two layers. SSL recording protocol is based on TCP, which provides basic functions such as data encapsulation, compression and encryption for high-level protocols. SSL handshake protocol is based on SSL recording protocol. Users authenticate, negotiate encryption algorithms and exchange encryption keys before the actual data transmission begins.

1. Generate a certificate that can be self-signed or obtained from the SSL Certificate Authority.

Keytool in JDK is a certificate management tool that can generate self-signed certificates.

The system I use here is deepin, and then generate the command as follows (if you can't find the keytoo command, configure the java environment first)

The name I specify is tomcat.keystore, and the alias is tomcat. The password is set by myself. I use tomcat here. The last one can be pressed directly by enter.

Keytool-genkey-alias tomcat-keyalg RSA-keystore / home/gzr/tomcat.keystore

My command execution record is as follows, (premise: create a directory locally, otherwise it will fail)

The result is that the corresponding file is generated, as follows:

# Port number server.port: 844 certificate name server.ssl.key-store: e:\ work\ rave\ tomcat.keystore# KeyStore password server.ssl.key-store-password: duan123server.ssl.keyStoreType: JKSserver.ssl.keyAlias: tomcat
