MySQL Connector/J is not difficult to configure and facilitates the connection between Java-based applications and MySQL databases. Developers can create connection pools and JDBC data resources to use for their Java application.
MySQL Connector/J enables Java-based applications that work with MySQL databases to establish the connection and run queries against the database, call stored procedures, manage input and output parameters, extracting and retrieving data from the database columns, and the list of scenarios does not end here.Īdditionally, the JDBC driver can be used with Tomcat, JBoss, Spring, GlassFish or other similar servers. It is particularly useful for database editing tools and viewers. Thanks to MySQL Connector/J, Java-based applications can easily connect to a MySQL server instance and retrieve information regarding containing tables and entries. It does not rely on the MySQL client libraries. The connector uses a JDBC driver for retrieving information from the database tables and for other transactions. The driver fully supports the MySQL database functionality and enables other applications to connect to the database. So it will not be connecting to the database server it will show an error as authentication failed for using the user as Postgres.MySQL Connector/J is a database driver designed to help developers access the MySQL databases from the applications created with Java.
But postgres123 is the incorrect password of user Postgres.
An incorrect password is not accepted in the connection string.To connect the database server, we need a correct password for the connection string.As we know that database URL, database driver, database user, and database user password are the important parameter while making the connection string.We need to define the correct password of the user into the connection string, the wrong password will issue the error i.e. Database user password – This is the password of the database user which was we have used in the connection string.It will issue an error that permission is denied. Without connecting permission, it will not connect to the database server. The user which we were using has permission to connect to the database server. This is the database user which we were using to connect the database server. Database username – This parameter is also important while connecting to the database server using the connection string.This will contain the driver information of the database server.
We need to define different database drivers for different databases.
