I was going through 2 way SSL in springboot. I have made all correct configuration service tomcat server and service caller RestTemplate. but I was getting error as "java.security.cert.CertificateException: No subject alternative names present"
After going through solutions, I found, JVM needs this certificate otherwise it gives handshaking error.
Now, how to add this to JVM.
go to jre/lib/security/cacerts file. we need to add our server certificate file to this cacerts file of jvm.
Command to add server cert to cacerts file via command line in windows.
C:\Program Files\Java\jdk1.8.0_191\jre\lib\security>keytool -import -noprompt -trustcacerts -alias <alias_of_ssl_cer_file> -file <path_of_ssl_cert_file.cer> -keystore <path_of_jdk_cacerts_file>-storepass changeit
Check server cert is installed or not:
C:\Program Files\Java\jdk1.8.0_191\jre\lib\security>keytool -list -keystore cacerts
you can see list of certificates installed:
