1.Class.forName()报错问题

Class.forName()报错连接数据库的时候要用到try catchString url = "jdbc:mysql://localhost:3306/survey?user=root&password=&useUnicode=true&characterEncoding=utf-8&autoReconnect=true&failOverReadOnly=false"; protected Connection conn=null; protected PreparedStatement pstmt; protected ResultSet rs=null; static{ try{ Class.forName("com.mysql.jdbc.Driver"); }catch(Exception e) { e.printStackTrace(); } } /** * Connect Database */ public void getConn() { String url = "jdbc:mysql://localhost:3306/survey?user=root&password=&useUnicode=true&characterEncoding=utf-8&autoReconnect=true&failOverReadOnly=false"; try { conn = DriverManager.getConnection(url); } catch (Exception e) { System.out.println("Database Conn Failed !"); } }
