Project Structure



pom.xml

POM stands for project object model. It's the fundamental unit of work in Maven. It is an XML file that contains information about the project and configuration details used to build the project. It downloads required libraries easily using POM XML tags.

Create WebController

The @Controller annotation has been part of the framework for a very long time.@Controller annotation designates that the annotated class is a controller. It is autodetected through classpath scanning.
package com.knf.dev.demo.springbootdatablepagination.controller;

import com.knf.dev.demo.springbootdatablepagination.vo.Vo;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import java.util.ArrayList;
import java.util.List;

@Controller
public class WebController {

    @GetMapping({"/", "/view"})
    public String view() {
        return "index";
    }

    @GetMapping({"/getcall"})
    public ResponseEntity<Vo> listAllUsers() {

        // Dummy list of values
        List<String[]> obj = new ArrayList<>();
        for (int i = 1; i <= 1000; i++) {
            String uname = "username-";
            String lname = "lastname-";
            String Id = "Id-";
            String email = "sibinknf@gmail.com-";
            String pin = "pin-";
            String mStringArray[] = {uname + i, lname + i, Id + i, 
                                        email + i, pin + i};
            obj.add(mStringArray);
        }
        Vo vo = new Vo();
        vo.setData(obj);
        return new ResponseEntity<>(vo, HttpStatus.OK);
    }
}

Vo.java

package com.knf.dev.demo.springbootdatablepagination.vo;

import java.util.List;

public class Vo {
    private List<String[]> data;

    public List<String[]> getData() {
        return data;
    }

    public void setData(List<String[]> data) {
        this.data = data;
    }
}



Spring Boot Main Driver

The Spring Boot application's main class contains a public static void main() method that starts up the Spring ApplicationContext.
package com.knf.dev.demo.springbootdatablepagination;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringbootdatablepaginationApplication {

   public static void main(String[] args) {
      SpringApplication.
        run(SpringbootdatablepaginationApplication.class, args);
   }
}

Learn Java 8 streams with an example - print odd/even numbers from Array and List

Example 1: Java 8 program to print odd numbers from a List   import java.util.Arrays; import java.util.List; import java.util.stream.Collectors; /*Java 8 Program to find Odd Numbers from a List*/ public class DriverClass { public static void main( String [] args) { List < Integer > numbers = Arrays. asList( 1 , 4 , 8 , 40 , 11 , 22 , 33 , 99 ); List < Integer > oddNumbers = numbers.stream(). filter(o -> o % 2 != 0 ). collect(Collectors.toList()); System.out.println(oddNumbers); } } 1. Initialize List using Arrays.asList() method. Java's built-in Arrays.asList() method converts an array into a list. This method takes an array as an argument and returns a List object. 2.  Java List interface provides stream() method which returns a sequential Stream with list of Integer as its source. 3. The Java stream filter() method allow

Java Stream API - How to convert List of objects to another List of objects using Java streams?

Image
In this section, we will show you how to convert a List of objects to another List of objects in Java using the Java streams map(). The ‘map’ method maps each element to its corresponding result. Java Stream API   The Java Stream API provides a functional programming approach over the object oriented capabilities of Java. It is used for processing collections of objects. The Stream in Java can be defined as a sequence of elements from a source List, Set or Array. Most of the stream operations return a Stream. This avails engender a chain of stream operations(stream pipe-lining). The streams withal support the aggregate or terminal operations on the elements. for example, finding the sum or maximum element or finding the average etc...Stream operations can either be executed sequentially or parallel. when performed parallelly, it is called a parallel stream.   Stream map() Method   The Java 8 Stream map() is an intermediate operation. It converts Stream<obj1> to Stream<obj2>

Top 5 Java ORM tools - 2024

Image
  The term ORM refers to object-relational mapping, which uses objects to adapt programming languages to database systems while allowing them to function with SQL and object-oriented programming ideas. Any kind of database management system that can accomplish object mapping to the table in the virtual system is suitable for the implementation of ORM. Java has a wide variety of ORM tools, some of which are mentioned below: 1. Hibernate Hibernate is a lightweight, open-source, non-invasive Java ORM (Object-Relational Mapping) framework that allows developers to create objects that function independently of database software and create persistence logic in any Java or JavaEE application. It offers an abstraction layer, so developers don't have to bother about implementations; Hibernate handles these tasks internally, such as connecting to databases and creating queries to carry out CRUD operations, among other things. Persistence logic development is done with it. Persistence logic r

Java - Blowfish Encryption and decryption Example

Image
Blowfish is an encryption method developed by Bruce Schneier in 1993 as an alternative to the DES encryption method. It is significantly faster than DES and provides good encryption speed, although no effective cryptanalysis technique has been found to date. It is one of the first secure block ciphers that is not protected by any patents and is therefore freely available for anyone to use. This is a symmetric block cipher algorithm. Block size: 64 bits Key size: variable size from 32 to 448 bits number of subsections: 18 [P-array] number of rounds: 16 number of substitution blocks: 4 [each with 512 records of 32 bits each] develop  Example 1: Encryption and decryption using Blowfish import java.io.UnsupportedEncodingException; import java.nio.charset.Charset; import java.security.InvalidKeyException; import java.security.NoSuchAlgorithmException; import java.util.Base64; import javax.crypto.BadPaddingException; import javax.crypto.Cipher; import javax.crypto.IllegalBlockSizeExc
