java.sql.SQLException: Unknown system variable 'query_cache_size'

Question

I have a app running with JDBC and get data from MySQL, but I can\'t build it because of this error :

java.sql.SQLException: Unknown system variable \'query         


        

Answer 1

This exception is related to pom.xml dependency. When I use below dependency in pox.xml:

 
      mysql
      mysql-connector-java
      6.0.5
 

It shows exception:Caused by: java.sql.SQLException: Unknown system variable query_cache_size

But, when I use below dependency:

  
            mysql
            mysql-connector-java
            8.0.13
  

It works.You have to use latest dependency
