Exception handling is a crucial aspect of Java programming, particularly when designing APIs and ensuring robust application behavior. This article outlines best practices for handling exceptions in Java, using Spring Boot for RESTful APIs, and emphasizes the importance of providing clear, helpful error messages to consumers. Here’s a comprehensive look into exception handling, using references Continue Reading »
In a typical monolithic architecture, applications often interact with a single database. However, there are scenarios where you might need to integrate multiple databases, such as when handling legacy systems or optimizing for performance. With Spring Boot, this is not only possible but can be managed efficiently using DataSource, EntityManager, and TransactionManager. In this blog, Continue Reading »
Spring Boot is known for its simplicity and ease of use, largely due to its extensive use of annotations. These annotations help configure and manage the application in a declarative way, reducing boilerplate code and enhancing readability. Here, we’ll explore some of the most commonly used annotations in Spring Boot. 1. @SpringBootApplication This is a Continue Reading »
Introduction: In Spring Boot applications, interacting with databases is a fundamental task. Whether you’re fetching data, updating records, or performing complex queries, efficient database operations are crucial for application performance. One powerful tool at your disposal for constructing dynamic queries is the Criteria API, which allows you to build queries programmatically and dynamically based on Continue Reading »
In the ever-evolving landscape of software development, Google’s Dialogflow is a powerful tool that enables developers to build conversational interfaces form applications, and integrating it with a Spring Boot backend can provide a seamless and efficient user experience. In this guide, we will explore the steps to integrate Dialogflow into a Spring Boot application, empowering Continue Reading »
In today’s digital world, security is a major concern, and 2-factor authentication (2FA) is one way to increase security. 2FA adds an extra layer of protection to your account by requiring users to provide two forms of authentication to access it. This usually includes something the user knows (such as a password) and something they Continue Reading »
Sometimes it’s our application requirement to deal with multiple databases. Spring Boot helps us to configure multiple databases in a single application. This blog will help to configure multiple datasources into a spring boot application. To use multiple DataSources, let’s add the following details in the property file. Here we configured ‘foo’ datasource and ‘bar’ Continue Reading »
This blog is about to send push notifications with spring boot and FCM. I will tell you how to send push notifications from the server. What is FCM? Firebase Cloud Messaging (FCM) is a cross-platform messaging solution that lets you reliably send messages at no cost. How FCM work Registration: When application gets installed it Continue Reading »
Sometimes we have to configure property files from outside of classpath so that anyone can access this file without looking into application. Spring boot provides many ways to configure this but most of them are used only if we read the property file from classpath if we are going to read from file system then Continue Reading »
