数据库访问被拒绝连接问题

Question

I am trying to make mysql database connection from my war file using jdbc connection string as shown below:-

    String connectionURL = "jdbc:mysql://localhost:3306/DatabaseName? user=DatabaseUserName;password=DatabasePassword";

Now my war file and database both available on server, & i am doing my execution from server itself. But the problem is that i am getting below error which says:-

    INFO: java.sql.SQLException: Access denied for user 'grandsho_root;password=pwd'@'localhost' (using password: NO)

where

grandsho_root is my user, pwd is my password ...I need to know what exactly is this problem? Do i need to perform GRANT ALL command. or something like that?

Answer 1

When you get the message "(using password: NO)" this means you were trying to connect without a password set. The log message tells you that the user "grandsho_root;password=pwd" is not allowed to connect. This means your connection string is wrong because you use ; to separate your parameters instead of a &. This is how your connection string should look:

jdbc:mysql://localhost:3306/DatabaseName?user=sqluser&password=sqluserpw

When you still have problems please check if your user is set up correctly. Check that grandsho_root has a password set, that he is allowed to connect from localhost and you granted the necessary privileges to your schema.
