Data validation is a basic requirement for any application. This is more significant for web applications that accept data as input. Bean Validation or commonly known as JSR-380 is a Java standard that is used to perform validation in Java applications. To perform validation, data Items are applied constraints. As long as the data satisfies […]Continue reading

When you develop a Spring Bool RESTful service, you as a programmer are responsible for handling exceptions in the service. For instance, by properly handling exceptions, you can stop the disruption of the normal flow of the application. In addition, proper exception handling ensures that the code doesn’t break when an exception occurs. Another important […]Continue reading

When developing REST APIs, it is important to have accurate and well-structured documentation of your API. This documentation is the reference point for anyone who wants to use your API. Spring REST Docs helps you to achieve it. Spring REST Docs take a different approach than any other traditional tools like Swagger. For more information on […]Continue reading

Enterprise Applications developed using the Spring Framework use different types of configuration properties to configure the application at runtime. These configuration properties help in connecting to databases, messaging systems, perform logging, caching, and lots more. It is common to store configuration properties in external .properties and .yml files. There are various ways of reading external […]Continue reading

Using API Gateways is a common design pattern with microservice architectures. API Gateways allow you to abstract the underlying implementation of the microservices. Microservices based systems typically have a large number of independent services. One challenge in such systems is how external clients interact with the services. If external clients interact directly with each microservices, […]Continue reading

A Spring Boot RESTful service is typically divided into three layers:  Repository, Service, and Controller. This layering helps to segregate the RESTful application responsibilities and enabling loose coupling between the objects. When you develop a layered RESTful application, you will also need to test the different layers. In this post, I will discuss testing Spring […]Continue reading

RabbitMQ is a common messaging broker which allows applications to connect and communicate. It’s common for services in microservices-based systems to communicate asynchronously through messaging. In order to create such a message-based system, you need a message broker, aka messaging server. A message broker can support several messaging patterns. Typically, a message sender sends a […]Continue reading

Introduction In this article, we will look at Spring Framework’s support of immutable property binding. We described Spring external configuration in this article and also provided a more detailed article about the Java bean properties binding. In this article, we will demonstrate constructor binding using the merchant account configuration in this article. Constructor binding enables […]Continue reading
