      • connect

        public <T extends Closeable> T connect​(String hostname,
                                       int portNumber,

                                throws IOException
        从接口复制的说明: SocketFactory
        Creates a new socket or channel using the given properties. Properties are parsed by the driver from the URL. All properties other than sensitive ones (user and password) are passed to this method. The driver will instantiate the socket factory with the class name given in the property "socketFactory", where the standard is com.mysql.cj.protocol.StandardSocketFactory Implementing classes are responsible for handling synchronization of this method (if needed).
        指定者:
        connect 在接口中 SocketFactory
        类型参数:
        T - result type
        参数:
        hostname - the hostname passed in the URL. It will be a single hostname, as the driver parses multi-hosts (for failover) and calls this method for each host connection attempt.
        portNumber - the port number to connect to (if required).
        pset - properties passed to the driver via the URL and/or properties instance.
        loginTimeout - login timeout in milliseconds
        返回:
        a socket connected to the given host
        抛出:
        IOException - if an I/O error occurs

      • performTlsHandshake

                                            throws IOException
        从接口复制的说明: SocketFactory
        If required, called by the driver during MySQL protocol handshake to transform original socket to SSL socket and perform TLS handshake.
