1.
現在工程(不是Src)上右鍵--Build Path--Add External Archives,選擇驅動下的那個jar包，這是release版本，bin目錄下的是debug版本。
示例在docs下的connector-j.html，里面有例子（其中的test是數據庫名，換位自己的）。
復制代碼 代碼如下:m.survivalescaperooms.com
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
Connection conn = null;
...
try {
conn =
DriverManager.getConnection("jdbc:mysql://localhost/test?" +
"user=monty&password=greatsqldb");
// Do something with the Connection
...
} catch (SQLException ex) {
// handle any errors
System.out.println("SQLException: " + ex.getMessage());
System.out.println("SQLState: " + ex.getSQLState());
System.out.println("VendorError: " + ex.getErrorCode());
}
2.可以直接在MySql控制臺下創建數據庫，也可以在通過執行 "/. 絕對路徑名"。 “--”是注釋符。
