📬 cURL Annotation for Spring (Java)

The cURL annotation helps you generate a Postman collection directly from your Spring Rest API code. By applying this annotation to your controller methods, you can automatically create detailed entries for each endpoint in your API.

🚀 How to Use

1. Add the Dependency

Maven

Add the following dependency to your pom.xml file:

<pom>
    <dependency>
      <groupId>io.bytescraft</groupId>
      <artifactId>cURL</artifactId>
      <version>0.0.3</version>
    </dependency>
    
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>${maven.compiler.plugin.version}</version>
                <configuration>
                    <annotationProcessorPaths>
                        <path>
                            <groupId>io.bytescraft</groupId>
                            <artifactId>cURL</artifactId>
                            <version>0.0.3</version>
                        </path>
                    </annotationProcessorPaths>
                </configuration>
            </plugin>
        </plugins>
    </build>
</pom>

Gradle

Add the following dependency to your build.gradle file:

implementation 'io.bytescraft:cURL:0.0.3'
annotationProcessor 'io.bytescraft:cURL:0.0.3'

2. Annotate Your Controller Methods

Use the cURL annotation on your controller methods to define the details for the Postman collection.

Example:

@RestController
@RequestMapping("/message")
public class MessageController {

    @cURL(name = "Get Message", folder = "/v1")
    @GetMapping(value = "/{id}" , produces = "application/json")
    public ResponseDTO getMessage(@PathVariable("id") Long id){
        ResponseDTO responseDTO = new ResponseDTO();
        responseDTO.setMessage("Hello World" + id);
        return responseDTO;
    }

    @cURL(name = "Post Message")
    @PostMapping(consumes = "application/json", headers = "Accept=application/json")
    public ResponseDTO postMessage(@Valid @RequestBody RequestDTO requestDTO) {
        ResponseDTO responseDTO = new ResponseDTO();
        responseDTO.setMessage("Hello World " + requestDTO.getName());
        return responseDTO;
    }

    @cURL
    @PutMapping(value = "/{id}" , produces = "application/json", consumes = "application/json")
    public ResponseDTO putMessage(@PathVariable("id") Long id, @RequestBody @Valid RequestDTO requestDTO) {
        ResponseDTO responseDTO = new ResponseDTO();
        responseDTO.setMessage("Hello World " + requestDTO.getName());
        return responseDTO;
    }

    @cURL
    @DeleteMapping(value = "/{id}" , produces = "application/json")
    public ResponseDTO deleteMessage(@PathVariable("id") Long id) {
        ResponseDTO responseDTO = new ResponseDTO();
        responseDTO.setMessage("Hello World");
        return responseDTO;
    }

    @cURL
    @GetMapping(value = "/filter" , produces = "application/json")
    public ResponseDTO filterMessages(@RequestParam(name = "query") String query, @RequestParam(name = "page", required = false) int page, @RequestParam(name = "size", required = false) int size) {
        ResponseDTO responseDTO = new ResponseDTO();
        responseDTO.setMessage("Hello World");
        return responseDTO;
    }
}

3. 🛠️ Create cURL.yaml File (Optional)

Create a cURL.yaml file at the src folder level in your Java project. This configuration file supports the following properties:

• collection.name: The name of the generated collection.
• collection.description: A description for the generated collection.

Example cURL.yaml file:

collection:
  name: cURL
  description: cURL is a command-line tool for getting or sending data including files using URL syntax.
  clients:
    - POSTMAN
    - THUNDER_CLIENT
  var:
    HOST: https://www.example.com
    PORT: 443
    ID: 40
postman:
  collection:
    pre-request: |
      pm.request.headers.add({key: 'userType',value: 'MANAGER'});
    post-response: |
      pm.collectionVariables.set("variable_key", "variable_value");

📂 Project Structure

Your project structure should look like this:

my-java-project/
├── src/
│   ├── main/
│   │   ├── java/
│   │   └── resources/
├── cURL.yaml
├── pom.xml (for Maven projects)
└── build.gradle (for Gradle projects)

4. 🛠️ Generate Postman Collection

Once your methods are annotated, build your project to generate a Postman collection. The specifics of this process will depend on the integration details of the cURL annotation, which typically involves running a Maven or Gradle task to process the annotations and output the Postman collection.
