fzhlee 人气:0想了解java获得mysql和oracle链接的类的相关内容吗，fzhlee在本文为您仔细讲解java获得mysql和oracle链接的类的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：java,mysql,oracle,链接，下面大家一起来学习吧。
本文实例讲述了java获得mysql和oracle链接的类。分享给大家供大家参考。具体如下：
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class ConnectDB {
private static final String MYSQL = "jdbc:mysql://";
private static final String ORACLE = "jdbc:oracle:thin:@";
private ConnectDB() {
}
public static Connection getInstance(String DBType, String url)
throws NoSuchDBException, SQLException
{
if ("mysql".equalsIgnoreCase(DBType))
return getMySqlConn(url);
if ("oracle".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。
