怎么连接不上mysql数据库

Answer 1

导入连接的jar包

写入连接文件
private final static String DRIVER = "com.mysql.jdbc.Driver";
private final static String URL = "jdbc:mysql://localhost:3306/tojapanonlinetest?useUnicode=true&characterEncoding=UTF-8";
private final static String USERNAME = "root";
private final static String PASSWORD = "root";

public static Connection getConnection() {
Connection con = null;
try {
Class.forName(DRIVER);
con = DriverManager.getConnection(URL, USERNAME, PASSWORD);
// System.out.println("连接成功");

} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
return con;
}
