本文实例讲述了java获得mysql和オラクル链接的类。分享给大家供大家参考。具体如下：
java.sql.connection; Import java.sql.drivermanager; Import java.sql.sqlexception; public final connectdb {private static final string mysql = "jdbc：mysql：//"; private static final string oracle = "jdbc：oracle ：shin：@"; private connectdb（）{} public static connection getInstance（string dbtype、string url）throws nosuchdbexception、sqlexception {if（" mysql ".equalsignorecase（dbtype））return getmysqlconn（url）; .equalsignorecase（dbtype））return getoracleconn（url）; return null;} public static void closeconn（connection conn）{if（conn！= null）{try {conn.close（）;} catch（sqlexception e）{e。 printstacktrace（）;}}} private static connection getmysqlconn（string url）throws sqlexception {connection conn = null; try {class.forname（ "com.mysql.jdbc.driver"）;} catch（classnotfoundexception e）{e.printstacktrace （）;} conn = drivermanager.getConnection（mysql + url、 "root"、 "root"）; return conn;} private static connection getoracleconn（string url）throws sqlexception {connection conn = null; try {class.forname（ " oracle.jdbc.driver.oracledriver "）;} catch（classNotFoundException e）{e.printstacktrace（）;} conn = drivermanager.getConnection（oracle + url、" scott "、" tiger "）; return conn;}}}}希望本文所述对大家的java程序设计有所帮助。
