Ip Location tracker using Java Spring and Geolite2 database

Mohammed Riyas — Sun, 06 Feb 2022 16:01:59 +0000

Before get into code you need first download GeoLite2 database. i drop link down. once you enter the GeoLite2 page you need signup and then only you can able to download the database. After click the download link, download page will open in that page you need to download Geolite2-city-20220201.tar.gz file. After download you need to extract that downloaded file using some gz file extracting app. then all set lets get back to code.

Send email using Spring boot Application

Mohammed Riyas — Mon, 24 Jan 2022 06:15:49 +0000

Hey amigos in this blog we gonna create an simple email sending springBoot Application.in this application i concentrated more in logical part. So i haven't give importance to design. My aim is to make as more simple and easy to understand.

To send email using spring application first of all you need to make right sure that enable less Secure apps in G-mail. After that then only we can send email from our application. I drop a link for how to enable less secure app please follow up.

https://youtu.be/Ee7PDsbfOUI

lets start with HTML part...

<html>
    <head>
        <title>TODO supply a title</title>
        <meta charset="UTF-8">
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
    </head>
    <body>
        <form action="add">
            <input type="text" name="username" placeholder="to whom you gonna send name"/>
            <input type="email" name="email" placeholder="email"/>
        <button type="submit">submit</button>
        </form>
    </body>
</html>

Nothing much complicated. iam just accepting the user name and email send it back to backend.


package com.mail2.mail2.controller;

import com.mail2.mail2.dot.mailRequest;
import com.mail2.mail2.dot.mailresponse;
import com.mail2.mail2.service.mailService;
import java.util.HashMap;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;

@Controller
public class controller {
    @RequestMapping("/")
    public String aa()
    {
        return "createUser";
    }
    @RequestMapping("/add")
    public String sp(@RequestParam("username")String name,@RequestParam("email")String email)
    {
       mailresponse mr= sendEmail(email);
        return "success";
    }
    @Autowired 
    private mailService service;
    public mailresponse sendEmail(String request) {
          Map<String, Object> model = new HashMap<>();
        model.put("Name", "riyas");
        model.put("location", "Bangalore,India");
        return service.sendEmail(request, model);
    }
}

create a Mail Request and Mail Response class

package com.mail2.mail2.dot;

public class mailRequest {
      private String name;
    private String to;
    private String from;
    private String subject;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getTo() {
        return to;
    }

    public void setTo(String to) {
        this.to = to;
    }

    public String getFrom() {
        return from;
    }

    public void setFrom(String from) {
        this.from = from;
    }

    public String getSubject() {
        return subject;
    }

    public void setSubject(String subject) {
        this.subject = subject;
    }

}

package com.mail2.mail2.dot;

public class mailresponse {
        private String message;
    private boolean status;

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public boolean isStatus() {
        return status;
    }

    public void setStatus(boolean status) {
        this.status = status;
    }

}

let me explain how the backend code work. first in controller class we accepting the username and email String.then sending email String to sendEmail method. Then creating Map object and send it to sendEmail method in MailService class.


package com.mail2.mail2.service;

import com.mail2.mail2.dot.mailRequest;
import com.mail2.mail2.dot.mailresponse;
import freemarker.template.Configuration;
import freemarker.template.Template;
import freemarker.template.TemplateException;
import java.io.IOException;
import java.nio.charset.StandardCharsets;
import java.util.Map;
import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Service;
import org.springframework.ui.freemarker.FreeMarkerTemplateUtils;

/**
 *
 * @author ELCOT
 */
@Service
public class mailService {
    @Autowired
    JavaMailSender sender;
    @Autowired
    Configuration config;
    public mailresponse sendEmail(String request, Map<String, Object> model) {
        mailresponse response = new mailresponse();
        MimeMessage message = sender.createMimeMessage();
        try {
            // set mediaType
            MimeMessageHelper helper = new MimeMessageHelper(message, MimeMessageHelper.MULTIPART_MODE_MIXED_RELATED,
                    StandardCharsets.UTF_8.name());
            // add attachment

            Template t = config.getTemplate("email-template.ftl");
            String html = FreeMarkerTemplateUtils.processTemplateIntoString(t, model);

            helper.setTo(request);
            helper.setText(html, true);
            helper.setSubject("created_successfully");
            helper.setFrom("muhammedriyas6262@gmail.com");
            sender.send(message);

            response.setMessage("mail send to : " + request);
            response.setStatus(Boolean.TRUE);

        } catch (MessagingException | IOException | TemplateException e) {
            response.setMessage("Mail Sending failure : "+e.getMessage());
            response.setStatus(Boolean.FALSE);
        }

        return response;
    }
}

here we see. I created a email template page in template folder in springboot application named emailtemplate.ftl extension.

learn usage about Hashcode and equals in JAVA

Mohammed Riyas — Tue, 18 Jan 2022 05:37:51 +0000

hashCode in Java is a function that returns the hashcode value of an object on calling.

import java.util.*;
public class HashCodes {
String name;
int id;

    public HashCodes(String name, int id) {
        this.name = name;
        this.id = id;
    }


    public static void main(String[] args) {
        HashCodes h=new HashCodes("ali",101);
        HashCodes h1=new HashCodes("al",101);
      Set s=new HashSet();
      s.add(h);
      s.add(h1);
        System.out.println(s);
    }

    @Override
    public String toString() {
        return "HashCodes{" + "name=" + name + ", id=" + id + '}';
    }

    @Override
    public int hashCode() {
        int hash = 7;
     //   hash = 83 * hash + Objects.hashCode(this.name);
        hash = 83 * hash + this.id;
        return hash;
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj) {
            return true;
        }
        if (obj == null) {
            return false;
        }
        if (getClass() != obj.getClass()) {
            return false;
        }
        final HashCodes other = (HashCodes) obj;
        if (this.id != other.id) {
            return false;
        }
        return true;
    }

java traditional method to remove duplicate String

Mohammed Riyas — Sun, 16 Jan 2022 05:09:07 +0000

I just saw a post in dev someone solved same problem using collections in java. so i thought let me try the same problem to solve in traditional way`

public class Main
{
public static void main(String[] args) {
String s="abbvcddgtttt";
char c[]=s.toCharArray();
char cc[]=new char[c.length];
int index=0;
char same=' ';
for(int i=0;i<c.length;i++)
{
for(int j=i+1;j<c.length;j++)
{
if(c[i]==c[j])
{
c[i]=' ';
}
}
if(c[i]!=' ')
{
cc[index]=c[i];
index++;
}
```
}
for(char i:cc)
{
```
System.out.println(i);
}
}
}
