Basic features of Java:
  • Easy to learn
  • Object-Oriented
  • Robust
  • Platform Independent
  • Secure
  • Multithreading
  • Architectural neutral
  • High performance 


Spring Boot: Spring Boot is a matured Java framework built on the top of Spring framework. Spring Boot has defaults for almost everything. However, it still lets us to chose what to configure. For Instance, If a certain configuration is provided, it will be used. However, If a configuration is not provided Spring will replace with default and proceed.

Basic features of Spring Boot:
  • Faster development
  • Easy to manage 
  • Autoconfiguration feature
  • Production-ready
  • Embedded container
  • Version management
  • Actuators

Thymeleaf: Thymeleaf is a server-side Java template engine for both web and standalone environments.


Spring Security: Spring Security is a framework that focuses on providing authentication and authorization mechanisms to Spring applications


H2 Database: H2 is a relational database management system written in Java. It can be embedded in Java applications or run in the client-server mode. It can be used also in-memory mode. Here we are using the H2 Database engine as in-memory mode.


Maven: The Maven is a powerful project management tool that is based on POM (project object model). A Project Object Model or POM is the fundamental unit of work in Maven. It is an XML file that contains information about the project and configuration details utilized by Maven to build the project. It contains default values for most projects. Some of the configurations that can be designated in the POM is the project dependencies, the plugins or goals that can be executed, the build profiles, and so on. Other information such as the project version, description, developers, mailing lists and such can withal be designated.

8. Spring Framework Annotations Used In This Project

@SpringBootApplication: The @SpringBootApplication annotation is a convenience annotation that combines the @EnableAutoConfiguration, @Configuration and the @ComponentScan annotations in a Spring Boot application. The @EnableAutoConfiguration annotation enables Spring Boot to auto-configure the application context. The @Configuration is annotated at the class level to indicate that a class declares one or more @Bean methods and may be processed by the Spring container to generate bean definitions and service requests for those beans at runtime. The @ComponentScan annotation is used with the @Configuration annotation to tell Spring the packages to scan for annotated components.


@Autowired: We can use Spring @Autowired annotation for spring bean autowiring. @Autowired annotation can be applied on variables and methods for autowiring byType. We can also use @Autowired annotation on constructor for constructor based spring autowiring.


@Bean: The @Bean annotation tells that a method produces a bean to be managed by the Spring container. It is a method-level annotation. During configuration (@Configuration), the method is executed and its return value is registered as a bean within a BeanFactory.


@Controller: 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 a specialization of @Controller and is autodetected through classpath scanning. 


@RequestMapping: The @RequestMapping is used to map web requests onto specific handler classes and/or handler methods. @RequestMapping can be applied to the controller class as well as methods.


@Service: This is an alternative to @Component that specifies you intend to use the class as part of your service layer. However, it doesn’t actually implement anything differently than @Component.


@Repository: The @Repository annotation is used to indicate that the class provides the mechanism for storage, retrieval, search, update and delete operation on objects.


@EnableWebSecurity: @EnableWebSecurity is used for spring security java configuration. Add this annotation with @configuration on top of your security java class that extends WebSecurityConfigurerAdapter.


@Entity: The @Entity annotation specifies that the class is an entity and is mapped to a database table.


@Table: The @Table annotation specifies the name of the database table to be used for mapping.


@Id: The @Id annotation specifies the primary key of an entity


@GeneratedValue: The @GeneratedValue provides for the specification of generation strategies for the values of primary keys.


@Column: The @Column annotation is used to specify the mapped column for a persistent property or field. If no Column annotation is specified, the default value will be applied.

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
