HTTP Method for API Calls in Spring Boot

In modern web applications, the need to interact with external APIs is commonplace. In this article, we will explore how to implement HTTP methods for API calls in a Spring Boot application. We’ll break down the process, focusing on GET, POST, PUT, and DELETE methods using a custom HttpService.

HTTP Method for API Calls in Spring Boot

Dependencies

Before we start, ensure that you have the following dependencies in your pom.xml file:

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.13</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.11.3</version>
</dependency>

Service Class Structure

We will create a service class that handles the HTTP methods. The class will leverage Spring’s @Autowired feature to inject necessary services, such as HeaderService, HttpService, UserService, and APIResponseUtil.

Code Overview

@Service
public class ApiService {
@Autowired
    private HeaderService headerService;
    @Autowired
    private HttpService httpService;
    @Autowired
    private UserService userService;
    @Autowired
    private APIResponseUtil apiResponseUtil;
    private…
