Mysql Connection with out password using corejava program

Question

I want to connect to a MySQL database. While installing MySQL I did not give any password, so in my program I did the same but I am getting error on connection. I am using p

Answer 1

The password argument should be set to null because even an empty String "" implies that there is a password.

DriverManager.getConnection("jdbc:mysql://localhost:3306/easylibdb1","root",null)

Answer 2

using password: NO - this means the program is not passing any password, in your case that is correct.

Since you mention that you are reading the values from the properties file, I don't see you doing that in the code you have posted. If you are really reading the values from the properties file in your actual code, and the MySQL server is a remote server, then make sure that you grant relevant permissions on the remote MySQL server with the below statement

grant all privileges on easylibdb1.* to 'root'@'192.168.1.51' to allow connections originating from 192.168.1.51

or

grant all privileges on easylibdb1.* to 'root'@'%' to allow connections originating from anywhere

Answer 3

Pass null as password instead of an empty String. That should make it work.

con = DriverManager.getConnection("jdbc:mysql://localhost:3306/easylibdb1","root",null);

From what I see right now, you're actually not using the values from the properties file.

Answer 4

According to you, you are passing username as root and password as empty string.And your connection is established through

con=DriverManager.getConnection("jdbc:mysql://localhost:3306/easylibdb1","root","");

So change your function as

con=DriverManager.getConnection("jdbc:mysql://localhost:3306/easylibdb1","root",null);

Then it will work. Or change the password in the application.properties file as

password=

Answer 5

If it's really password="" what stands in your properties file, then "" will be sent as password. Not an empty string but the two quote signs.

Answer 6

URL=jdbc\:mysql\://192.168.1.51:3306/easylibdb1
USER=root
PASSWD=
DRIVER=com.mysql.jdbc.Driver

Please set ur PASSWORD Field as blank.. Don't put quote.
