“Found interface com.mysql.jdbc.Connection, but class was expected ”
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
In mysql-connecter-java-5.0 Statement is a class. in 5.1, it’s an interface.
The code you write shouldn’t care too much. But if you compile against the new version, then run against the old version, you’ll have this problem.
我項目中用的是5.1的版本,而在5.1中Connection 和Statement 為接口,而在5.0版本中為class。將jar包替換為mysql-connecter-java-5.0即可
總結
