From API contract to documentation portal: streamline your workflow and deliver the best API experience. Built for engineers and tech writers.

Manually writing Swagger docs? 😓 It's time to level up your workflow and let your **code generate the docs for you** — automatically! If you're using **Spring Boot** , the best way to do this is with: ## ✅ Springdoc OpenAPI ### 🔧 What It Does **Springdoc OpenAPI** is a free, open-source integration that **automatically generates Swagger UI and OpenAPI 3 documentation** from your Spring Boot REST APIs. No manual effort required — just annotate your controllers as usual! ## 🛠 How to Set It Up ### 1. Add Dependency in `pom.xml` <dependency> <groupId>org.springdoc</groupId> <artifactId>springdoc-openapi-ui</artifactId> <version>1.7.0</version> <!-- use latest --> </dependency> > 📦 Works with Maven — use the corresponding dependency for Gradle if needed. ### 2. Run Your Application and Access Swagger UI Once your app is running, open your browser and visit: http://localhost:8080/swagger-ui/index.html > 🎉 You'll see a full, interactive Swagger UI with all your API endpoints, parameters, responses, and models! ## ✅ What It Supports * REST Controllers (`@RestController`) * Mappings like `@GetMapping`, `@PostMapping`, etc. * Bean validation annotations (`@NotNull`, `@Size`, etc.) * Spring Security annotations (with extra config) * Custom documentation with: * `@Operation` * `@ApiResponse` * `@Parameter` ## 🔍 Bonus: Get Raw OpenAPI Spec For exporting your API or generating clients: http://localhost:8080/v3/api-docs > Returns the OpenAPI 3 JSON spec! ## ✨ Example: Auto-Documented Controller @RestController @RequestMapping("/api") public class UserController { @GetMapping("/users") public List<User> getAllUsers() { return userService.getAllUsers(); } @PostMapping("/users") public User createUser(@RequestBody @Valid User user) { return userService.createUser(user); } } > The above controller will automatically show in Swagger UI — no extra setup needed! ## 🙌 Final Thoughts Using **Springdoc OpenAPI** is a quick win for any Java microservice project. It ensures: * ✅ Always up-to-date documentation * 🤝 Easier collaboration with frontend/backend/devops * 🚀 Faster onboarding for new devs * 🧹 Eliminates outdated manual Swagger files ## 🔗 Useful Links * Springdoc OpenAPI GitHub Repo * Official Documentation * Swagger UI Demo * OpenAPI 3.0 Spec
