Spring Web applications and RESTful services contain controllers responsible to process requests and send back responses. At times you might need to perform certain operations on client requests before it reaches the controller. Similarly, you might need to perform operations on responses sent back by controllers to clients. You can achieve this using filters in […]Continue reading

Distributed Microservices Systems typically comprise a large number of smaller services. These services communicate with each other to perform operations. In order to communicate, one service needs the address of the other service to call. However, service addresses are dynamic in modern microservices systems. For example, if a service is running on one IP and […]Continue reading

We use scheduling to schedule jobs in a Spring Boot application. For instance, you can implement scheduling to perform some task at a specific time, or repeat after a fixed interval. In this post, you’ll learn how to use the Spring @Scheduled annotation to configure and schedule tasks. Spring Boot @Scheduled Annotation Example Let’s say […]Continue reading

Apache Kafka is an open-source Message Bus that solves the problem of how microservices communicate with each other. Spring for Apache Kafka, also known as spring-kafka. It is a  project that applies core Spring concepts to Kafka-based messaging solutions. Spring-kafka provides templates as high-level abstractions to send and consume messages asynchronously. In this post, you […]Continue reading

The Spring Boot CLI (Command Line Interface) is a command-line tool that you can use to run and test Spring Boot Applications from a Terminal. The CLI is one of the fastest ways to develop a Spring-based application. How does Spring Boot CLI work? It uses Spring Boot Starter and Spring Boot AutoConfigurate components to […]Continue reading

Spring Boot Actuator is a sub-project of the Spring Boot Framework. It uses HTTP endpoints to expose operational information about any running application. The main benefit of using this library is that we get health and monitoring metrics from production-ready applications. Moreover, the gathering of metrics, understanding traffic, or knowing the state of the database, […]Continue reading

Internationalization or I18N is a process that makes your application adaptable to different languages and regions without engineering changes on the source code. You can display messages, currencies, date, time etc. according to the specific region or language, likewise you can say internationalization is a readiness of localization. Maven dependency You will only require the […]Continue reading

Spring Web applications and services need to process client requests sent over HTTP. When the HTTP clients send data with the request, the data is in the request body. On the application side, you need a mechanism to deserialize data sent in the request body to domain objects. This is done using the @RequestBody annotation. […]Continue reading

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
