如何读取java项目中的jdbc.properties文件

Properties props = Resources.getResourceAsProperties("jdbc.properties"); String url = props.getProperty("jdbc.url"); String driver = props.getProperty("jdbc.driverClass"); String username = props.getProperty("jdbc.username"); String password = props.getProperty("jdbc.password"); Class.forName(driver).newInstance(); Connection conn = (Connection) DriverManager.getConnection(url, username, password);

jdbc.driverClass = com.mysql.jdbc.Driver jdbc.url = jdbc\:mysql\://127.0.0.1\:3306/LY?useUnicode\=true&characterEncoding\=UTF-8&zeroDateTimeBehavior\=convertToNull&allowMultiQueries\=true jdbc.username = root jdbc.password = root jdbc.minPoolSize=2 jdbc.maxPoolSize=20 jdbc.checkoutTimeout=3000 jdbc.maxStatements=50 jdbc.testConnectionOnCheckin = false jdbc.idleConnectionTestPeriod =18000
