A design pattern is a generic, reusable solution for a commonly occurring design problem. There are many design patterns in Java. The Circuit breaker pattern is one of such patterns which is applicable for applications that interacts with each other using remote service calls.
Hibernate is one of the leading frameworks used for Database interactions, also it is one of the JPA Specification implementer.JPA 2.1 introduced Entity Graphs feature as a more advanced way of handling performance issues.
Jackson-databind is the one of the libraries widely used in modern spring-based applications for serialization or deserialization from/to JSON. Jackson library will convert object to JSON, and vice versa.
As we have stepped into a New Year, it is the perfect time to first retrospect what Java brought to us in 2018, and what all can we expect in 2019. At the same time, it is also the perfect time of the year to understand what all we know about latest Java concepts and what we should be prepared to learn.
Unit testing is one level of software testing where individual components of a software are tested. The purpose of the unit testing of a Java software development is to validate each unit performs as designed. A unit is the smallest testable component, like methods.
Java is an object oriented language, i.e. A Java program deals with the creation of objects, their interaction etc. We can use Java Database Connectivity (JDBC) API to for accessing the database. This approach possesses some challenges.
Today we will see how we can implement different version of same service in REST terminology. Now a days we have a boom of developing smaller services using REST and in microservice eco system, those services interact with each other and produce the final business output.
Large organizations maintain many web applications written in multiple languages. One could be a Java web development, another is a .NET application etc. There could be situations wherein cross application data sharing is required.
Hello friends today in this tutorial, we will check how we can deploy our spring boot application in AWS EC2 easily. Now a days Spring boot and AWS has got lots of momentum and lots of projects are being deployed in AWS with underlying framework as spring boot.
Spring framework is a popular Java framework that provide support for various requirements of a Java application. It supports dependency injection, web services, MVC pattern etc. The main aim of a framework.
Technology: Spring Profiles provides conditional approach to load the parts of the application only in certain environments. It is used to load one of the same types of available beans based on environment configuration.
Amazon Cognito is a cloud based service that offers authentication, authorization and user management for applications. Application users can sign in using traditional user name - password combo, Multi factor authentication or by using third party services like Google, Facebook etc.
Technology:Containers are used deploy applications in an isolated environment, once we generate the container images can be deployed number of machines, but for a Java application building an image is not an easy way, we need to write a docker file.
Technology: In the present world all majority IDE`s supporting the HotSwap for web applications using embedded JDK HotSwap Mechanism without restarting the running web/application servers or deploying the application.
Technology: Spring Data is one module built on top of the spring framework for easy database transactions. It provides various interfaces, and annotation for easy outsource Java development.
In Microservice architecture, a monolithic application is split into multiple Smaller and independent applications. Each application manages a certain functionality independently and can be deployed/scaled independently.
Ribbon is the client-side load balancerwhich gives control over HTTP and TCP Clients. The main purpose of Ribbon is named client, each load balancer is one of the component that work together to connect to remote server.
Microservice architecture is a buzzword now-a days. As opposed to traditional monolithic applications, an application is deployed as a suite of smaller and independent applications each one managing a separate business operation.
Microservice architecture or simply Micro services has gained a lot of traction in recent times. They are better suited for agile methodology and ensure better continuous delivery. Big organizations like EBay, Amazon, and Netflix are embracing it.
