java连接mysql数据库

首先要安装驱动mysql-connector-java，是连接Mysql的jar包，下面有下载

打开myeclipse——Windows——Preference——Java——Installed JREs点击SunJDK——Edit——Add External JARs,然后选择mysql-connector-java包，添加完成

public static void main(String[] args) {
        // TODO Auto-generated method stub
        String driver = "com.mysql.jdbc.Driver";
        String url = "jdbc:mysql://127.0.0.1:3306/test";
        String user = "root";
        String pwd = "mysql";
        try{
            Class.forName(driver);
            Connection con = DriverManager.getConnection(url,user,pwd);
            if(!con.isClosed()){
                System.out.println("连接成功");
            }
        }catch(ClassNotFoundException e){
            e.printStackTrace();
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }
