Enable HTTPS in spring boot 2.0 with self-signed certificate
Nguyen Minh Thuan:
I'm following this tutorial using a self-signed certificate and enabling HTTPS in Spring Boot 2.0 just for testing purposes. In summary, the tutorial includes the following steps:
Use 1.Generate keystore keytool.
keytool -genkey -alias tomcat
-storetype PKCS12 -keyalg RSA -keysize 2048
-keystore keystore.p12 -validity 3650
2. Enable HTTPS in Spring Boot by adding some properties application.propertiesin the file.
server.port: 8443
server.ssl.key-store: keystore.p12
server.ssl.key-store-password: mypassword
server.ssl.keyStoreType: PKCS12
server.ssl.keyAlias: tomcat
3. Redirect HTTP to HTTPS (optional). I ignored this part.
But when I start my application, I get these errors:
org.apache.catalina.LifecycleException: Failed to start component [Connector[HTTP/1.1-8443]]

Verify the connector's configuration, identify and stop any process that's listening on port 8443, or configure this application to listen on another port.

Basically, the information is:
The private key must be accompanied by a certificate chain.
This is a self-signed certificate, so, of course, doesn't have a chain of trust. How can I fix this problem?
Here is my current application.propertiesfile:
server.port=8443
server.ssl.enabled=true
server.ssl.key-store=classpath:keystore.p12
server.ssl.key-password=123456
server.ssl.key-store-type=PKCS12
server.ssl.key-alias=tomcat
thank you very much for your help.

The problem is that in your keystore you don't have a pair of keys so that's because using the option -genkey you need the option -genkeypair to change it you don't have the private key:
-genkey generates a key, while -genkeypair generates a key pair (public and private key).
So I think this should work:
keytool -genkeypair -alias tomcat -storetype PKCS12 -keyalg RSA -keysize 2048 -keystore keystore.p12 -validity 3650
In spring boot config change ":" by "=" and add path to your keystore, I think your keystore.p12 is in your resources folder etc:
server.ssl.key-store = classpath:keystore.p12
server.ssl.key-store-password = mypassword
server.ssl.key-store-type = PKCS12
server.ssl.key-alias = tomcat
