2. Check whether close () is performed after MySqlConnection is used ()
3. Do not make the MysqlConnection connection static. Each connection creates a new connection.
Eg:
Copy the content to the clipboard program code
MySql. Data. MySqlClient. MySqlConnection mysqlConnection = new MySqlConnection (SDS. SMS. DAL. SqlHelper.
When the program throws an exception:Cocould not get JDBC Connection; nested exception is com. mysql. jdbc. exceptions. mySQLNonTransientConnectionException: Data source rejected establishment of connection, message from server: "Too connector connections" www.2cto.com 1. log on to MYSQL and go to the mysql/bin directory: mysql-u root-p Enter password: (Enter the password) where-u is followed by the user name, and-p requires a password, press enter an

GCF provides a convenient architecture. Generally, the following steps are used to operate the serial port:
1. Open the serial port: commconnection cc = (commconnection) connector. Open ("COMM: com3: baudrate = ......");
2. Open the input stream: inputstream is = cc. openinputstream ()
3. Open the output stream: outputstream OS = cc. openoutputstream ();
4. Write Data: OS. Write ()
5. Read data: Is. Read ()
