Kubernetes (K8S) is a popular container orchestration platform used for automating deployment, scaling, and managing containerized applications. One key aspect of developing applications for Kubernetes is ensuring proper documentation of APIs to enable seamless communication between services. In this article, we will focus on using springdoc-openapi-webmvc-core, a library that integrates Swagger OpenAPI with Spring Boot to generate API documentation automatically.
### Steps to Implement springdoc-openapi-webmvc-core
To help the beginner understand how to implement springdoc-openapi-webmvc-core, let's break down the process into steps using a table format:
| Step | Description |
|------|-------------|
| 1 | Add springdoc-openapi-webmvc-core dependency to your project |
| 2 | Configure the library in your Spring Boot application |
| 3 | Access the generated API documentation in your browser |
### Step-by-Step Implementation Guide
Now let's dive into each step in detail and provide the necessary code snippets to guide you through the implementation process.
#### Step 1: Add springdoc-openapi-webmvc-core dependency
You need to add the springdoc-openapi-webmvc-core dependency to your `pom.xml` file if you are using Maven. This dependency will enable Swagger OpenAPI documentation generation in your project.
```xml
org.springdoc
springdoc-openapi-webmvc-core
1.5.5
```
#### Step 2: Configure the library in your Spring Boot application
Next, you need to configure the library in your Spring Boot application to enable Swagger UI and API documentation generation. Create a new Spring Boot configuration class and annotate it with `@Configuration` and `@EnableSwagger2WebMvc`.
```java
import org.springdoc.core.SpringDocUtils;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.swagger.web.InMemorySwaggerResourcesProvider;
@Configuration
public class SwaggerConfig {
@PostConstruct
public void init() {
SpringDocUtils.getConfig().addAnnotationsToIgnore(SomeAnnotation.class);
}
}
```
#### Step 3: Access the generated API documentation
Once you have added the dependencies and configured the library, you can access the Swagger UI and API documentation by navigating to the following URL in your browser after running your Spring Boot application:
`http://localhost:8080/swagger-ui.html`
You should now see the API documentation generated for your Spring Boot application using springdoc-openapi-webmvc-core.
### Conclusion
In this article, we have discussed how to implement springdoc-openapi-webmvc-core in a Spring Boot application to generate API documentation using Swagger OpenAPI. By following the step-by-step guide and adding the necessary dependencies and configuration, you can easily document your APIs and facilitate communication between different services in a Kubernetes environment. Remember to keep your API documentation up to date as your project evolves to ensure seamless integration with other services. Happy coding!
