一、代码如下
private void select_Mysql() {
// TODO Auto-generated method stub
java.sql.PreparedStatement ps = null;
java.sql.Connection cn = null;
ResultSet rs = null;
try {
// Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
Class.forName("com.mysql.jdbc.Driver").newInstance();
cn = DriverManager.getConnection(
"jdbc:mysql://localhost:3306/learn?user=root&password=&useUnicode=true&characterEncoding=UTF8");
ps = cn.prepareStatement("select * from user");
rs = ps.executeQuery();
// rs.next();
// System.out.println(rs.getInt(1));
while (rs.next()) {
String name = rs.getString(2);
String passwd = rs.getString(3);
String phone = rs.getString(4);
String email = rs.getString(5);
System.out.println(name + " " + passwd + " " + phone + " " + email);
// System.out.println(name);
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
try {
rs.close();
cn.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
