java.sql.SQLException: Unknown initial character set index '255' received from server for connector 8.0.11

Question

While establishing the connection to a MySQL database, I\'m getting the following error

java.sql.SQLException: Unknown initial character set index \'255\' receiv         


        

Answer 1

I am using springboot,liquibase, mysql

I got solution: This error occur just because of mysql connector in dependency and mysql server you install not match(in my case i am using lower version mysql connector and latest mysql server). So just change scope of mysql connector to runtime:

maven

    
        mysql
        mysql-connector-java
        runtime
    

gradle

dependencies {
//... other dependencies
runtimeOnly group:'mysql', name:'mysql-connector-java'
}

Or if problem yet not solve then use same version or nearby version for both mysql server and mysql connector.
