The connection implementation class in Mysqldatasource implements the IsValid (int timeout) method

In the project, when we need to connect to MySQL database, we'd better choose to use database connection pool, that is, we need to choose DataSource.

When using C3p0 's Combopooleddatasource , it was found that the connection implementation class Newproxyconnection did not implement the isValid(int timeout) method After reviewing and testing the data, it is found that the connection implementation class in the Mysqldatasource in the MySQL driver package (specifically, which also informs you about it) implements the IsValid (int timeout) method.
