Tomcat Boot Certificate exception java.io.IOException:Alias name [CAS] does not identify a key entry

In the process of building CAS server, Tomcat turns on HTTPS, configures the key certificate, and the certificate is generated by Keytool

<connector port="8443"Protocol="Org.apache.coyote.http11.Http11Protocol"MaxThreads=" Max"Sslenabled="true"Scheme="HTTPS"Secure="true"ClientAuth="true"Sslprotocol="TLS"keystorefile="/home/workspace/server.keystore"Keystorepass="111111"/>

After starting the Tamcat, prompt the following error

Solve

Regenerate the secret key and passkeytool -list -keystore thekeystore

Check the type of secret key, it is Privatekeyentry is normal.

• Privatekeyentry, for the private key, configured on Tomcat's Server.xml (CAS service side)
• Trustedcertentry, for public key, configured on JDK (app service side)
