Description: The ‘RestController’ is an annotation in the Spring framework that combines the functionalities of @Controller and @ResponseBody. It is used to create RESTful web services, facilitating the construction of applications that follow the REST (Representational State Transfer) architectural style. This annotation allows controller methods to return data directly in JSON or XML format, eliminating the need to add the @ResponseBody annotation to each individual method. This simplifies API development, as it focuses on business logic and data manipulation, leaving serialization and response handling to Spring’s infrastructure. Additionally, ‘RestController’ efficiently handles HTTP requests using methods like GET, POST, PUT, and DELETE, making it an essential tool for modern web application development. Its use has become common in the development of web and mobile applications, where communication between client and server occurs through RESTful services, promoting interoperability and scalability of applications.
