使用java中的Prepared Statement将用户IP地址插入MySql表

Question

I need to insert user IP Address into MySql table using PreparedStatement. How can I do it?

I tried with following code in Servlet.

InetAddress ipaddress;
try {
    ipaddress = InetAddress.getLocalHost();
} catch (UnknownHostException e) {
    e.printStackTrace();
}

I want to know is there any better method than above to get IP Address ?? or I can continue with above code?

String insertquery = "insert into tablename (IPAdd) values (?)";

preparedStatement = conn.prepareStatement(insertquery);
preparedStatement.setString(1, ipaddress);// It's not a string so How can I set values here ?// Getting error here

Answer 1

If you want to get the IP then Instead of use :

preparedStatement.setString(1, ipaddress);

use :

// this will return the IP Host Adresse for example 192.168.1.2
preparedStatement.setString(1, ipaddress.getHostAddress());
