我认为我在这部分有问题，因为我使用不同的方式连接到数据库 public class Connect {

private java.sql.Connection conn=null;


public Connect () {}


public boolean dbConnect(){
boolean ok = false;              
try {
         try {
            Class.forName("com.mysql.jdbc.Driver");
         }
         catch(ClassNotFoundException ex){                                        
            ok = false;
         }
      conn=DriverManager.getConnection("jdbc:mysql://localhost:3306/myshelf?useServerPrepStmts=false", "myshelf", "myshelffoofysPASS");
       // conn=DriverManager.getConnection("jdbc:mysql://174.129.206.66:3306/myshelf","myshelf","myshelffoofysPASS");
        // conn=DriverManager.getConnection("jdbc:mysql://localhost/myshelf","root","");

         ok = true;
    }
    catch (SQLException e) {
         ok = false;
    }
return ok;
}


    public static Connection DbConn() throws SQLException {
        try {
            Class.forName("com.mysql.jdbc.Driver");
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }
     //  return DriverManager.getConnection("jdbc:mysql://174.129.206.66/myshelf","myshelf","myshelffoofysAPI");

         return DriverManager.getConnection("jdbc:mysql://localhost:3306/myshelf?useServerPrepStmts=false", "myshelf", "myshelffoofysAPI");
        }




public java.sql.Connection getConn() {
