jdbc connection url

A JDBC connection URL is a string that specifies the location of a database server and the database to connect to. It typically follows the format:

jdbc:<subprotocol>:<subname>

The subprotocol is the name of the driver used to connect to the database, and the subname is the name of the database or its location.

For example, the following is a JDBC connection URL for connecting to a MySQL database running on localhost:

jdbc:mysql://localhost:3306/mydatabase

In this example, "mysql" is the subprotocol, "localhost" is the hostname of the database server, "3306" is the port number, and "mydatabase" is the name of the database.

It is not recommended to include the password in the JDBC connection URL, as it can be a security risk. Instead, it is better to pass the password separately using the connection properties.

However, if you still want to include the password in the URL, you can do so by adding the "user" and "password" parameters to the URL, like this:

jdbc:<subprotocol>://<host>:<port>/<database>?user=<username>&password=<password>

For example, the following is a JDBC connection URL for connecting to a MySQL database running on localhost with the username "myuser" and password "mypassword":

jdbc:mysql://localhost:3306/mydatabase?user=myuser&password=mypassword

Again, it is not recommended to include the password in the URL, as it can be visible to anyone who has access to the system logs or configuration files.
