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
For a One-to-One relationship in JPA, each entity instance is related to a single instance of another entity. It means each row of one entity is referred to one and only one row of another entity. In this post, you’ll learn how to create a One-to-One relationship between two entities using JPA in a Spring […]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
The Spring Ioc container is at the core of the Spring Framework. BeanFactory and ApplicationContext provide implementations of the IoC container. Both BeanFactory and ApplicationContext are interfaces and there are several implementations that come out of the box with Spring. In this post, I will explain the differences between BeanFactory and ApplicationContext. Major Differences between […]Continue reading
In Relational Database Management Systems (RDBMS), a stored procedure is a batch of prepared SQL code grouped as a logical unit that you store in the database. Stored procedures allow reusability of SQL code. In this post, I will explain how to call MySQL stored procedures from a Spring Boot application. Dependency For the application […]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
The Spring framework has a library called Spring State Machine which is a model of computation that depends on the finite states. It can only be in one state at a given time, hence it is also called a finite state machine. The transitions of this State Machine are the changes in the status of […]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
