JHipster: Micronaut + Angular + SQL Database CRUD example

Hello everyone, today we will learn how to generate a Monolithic Full-stack web application that is a basic Employee Management Application using JHipster. Technologies used: Micronaut, Angular, H2DB, Maven.

User Interface



JHipster is an open-source application development platform to quickly generate, develop, & deploy modern web applications & microservice architectures using Angular or React or Vue and Spring Boot or Micronaut Frameworks.
Micronaut is a modern, JVM-predicated, full-stack Java framework designed for building modular, facilely testable JVM applications with support for Java, Kotlin and the Groovy language.

JHipster Micronaut Environment Setup

Step 1: Install Java 11, click here

Step 2: Install Node.js, click here

Step 3: Install JHipster using the following command
npm install -g generator-jhipster@6.10.5
or
yarn global add generator-jhipster@6.10.5
or
Download the JHipster Docker image, click here

Step 4(Optional): 
Install Maven or Gradle depends on you.
You normally don’t have to install anything, as JHipster will automatically install the Maven Wrapper or the Gradle Wrapper for you. If you don’t want to use those wrappers, go to the official Maven website or Gradle website to do your own installation.

Step 5: Install the JHipster Micronaut blueprint:
npm install generator-jhipster-micronaut@1.0.0

Creating a Web App using JHipster

Step 1: Create an empty directory in which you will create your application.
mkdir myapp
cd myapp

Step 2: To auto-generate your application, type below command
mhipster


Answer the questions asked by the generator to create an application tailored to your needs, like below:


Click Enter,

If everything goes fine, then you see the following output in your terminal:


Create the Entity called Employee

mhipster entity Employee
Answer the questions asked by the generator to create the entity.


If everything goes fine, then you see the following output in your terminal:


Running the Application

Once the application is generated, you can launch it using 
Maven 
./mvnw
Gradle
./gradlew
Starting the Micronaut application on port 8080:


The application will be available on http://localhost:8080

Demo

  • Select the Sign-in 


  • Enter the admin credentials to log in to the application.

  • Then select 'Employee',

  • You will get the Employee management page.


Next, You can open the project with your favourite IDE and start exploration,

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(...

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 Str...

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.IllegalBlockSiz...
