数据库连接池------druid
1.将jar包导入lib文件
测试连接的代码: /** * 使用Druid数据库连接池技术 */ private static DataSource source1; static{ try { Properties pros = new Properties(); InputStream is = ClassLoader.getSystemClassLoader().getResourceAsStream("druid.properties"); pros.load(is); source1 = DruidDataSourceFactory.createDataSource(pros); } catch (Exception e) { e.printStackTrace(); } } public static Connection getConnection3() throws SQLException{ Connection conn = source1.getConnection(); return conn; }
其中,配置文件定义在src下:druid.properties
url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF8";
username=root
password=12345
driverClassName=com.mysql.jdbc.Driver
