    6.2 Connection URL Syntax - MySQL

    What is a MySQL port & a JDBC url?
    Port: The network port MySQL uses to listen for connections (default: 3306). JDBC URL: A formatted string combining host, port, database name, and optional parameters (e.g., jdbc:mysql://host:port/dbname?useSSL=false). The MySQL username is the account you use to authenticate with the server.

    To connect a Java application to a MySQL database using JDBC, you need to use a specific URL format. The JDBC URL for MySQL follows a standard structure that includes the protocol, host, port, database name, and optional properties.

    Basic JDBC URL Format

    The basic format of the JDBC URL for MySQL is as follows:

    jdbc:mysql://[host1][:port1][,[host2][:port2]]...[/[database]][?propertyName1][=propertyValue1][&propertyName2][=propertyValue2]
    コピーしました。

    Here is a breakdown of the components:

    • jdbc:mysql: This specifies the protocol and sub-protocol for MySQL.

    • host: The hostname or IP address of the MySQL server. If not specified, it defaults to localhost.

    • port: The port number on which the MySQL server is listening. The default port is 3306.

    • database: The name of the database to connect to. This is optional.

    • properties: Additional connection properties in the form of key-value pairs, separated by &.
