MySQL Connector/J uses SSL to encrypt all data that is communicated between the JDBC driver and the MySQL server. It’s used in Java to connect and work with the MySQL database.
Change JDBC library from Connector/J 5.1.9 to (e.g.) Connector/J 5.1.5 and the application will throw a .jdbc4.CommunicationsException because it now trys to connect to localhost:6777 where no MySQL server is running. MySQL Connector/J is the driver that implements the JDBC API. The application will successfully establish a connection to MySQL server running on localhost:3306 although localhost:6777 has been specified. Just put any JDBC 4.x driver in the project classpath, and Java is able to detect it. Execute the Java application below with Connector/J 5.1.9 as JDBC library. In this above example, we no need to register a JDBC driver because since Java 1.6 and JDBC 4.0 API, it provides a new feature to discover automatically, it means the Class.forName is no longer required. Start MySQL server on default port 3306. Tomcat MySQL connection - Using JDBC to connect Tomcat to MySQL Stumped by Tomcat JDBC connections Cant get your head around MySQL drivers, connection pools, and JNDI resources This article will guide you step-by-step through connecting your MySQL database to Tomcat, in plain English. It seems that parseURL() has been corrected but getConnection() has not been updated to use the PORT (PORT.n) key of the connection properties map.įor the connection string "jdbc:mysql://localhost:6777" Connector/J 5.1.9 creates the properties mapĪnd trys to connect to localhost:3306 whereas Connector/J 5.1.5 will create Connection conn DriverManager. To query data from MySQL, you first need to establish a connection to MySQL using Connection object.
MYSQL JDBC STRING HOW TO
A good source for documentation - though a bit dated - on how to use this driver can be found here. In this tutorial, we will show you how to query data from MySQL using JDBC Statement and ResultSet objects. Any suggestions or direction would be appreciated.
It is a 'type 4' driver - a 'native-protocol pure Java driver'. By the way, I have multiple schemas that I will need to be able to access so as I understand from the MySQL docs I can leave the databasename blank or optional(). The JDBC driver always uses standard port 3306 for connection creation. JDBC is one way to access a mySQL database, and the official JDBC driver for MySQL is called MySQL Connector/J. The DriverManager.getConnection() methods do not use the specified non-standard port on the jdbc connection string (e.g.
