Java JDBC uses the configuration file to connect to the database: Create a file with the suffix ". properties". The file content includes: Database driver, connected database address, user name, password ......Take Mysql as an example to create the config. properties configuration file. Its content is as follows:DRIVER_CLASS = com. mysql. jdbc. DriverCONNECTION_URL = jdbc: mysql: // localhost: 3306/testCONN

The code in this article mainly lists the key code used to connect to the database. Other database access code is omitted. 1. oracle8/8i/9i Database (thin Mode)Class. forname ("oracle. JDBC.
