Which of the following best explains why API documentation is crucial in Spring Boot projects?
Think about how clear instructions help when using something new.
API docs provide clear instructions on how to use the API endpoints, making development faster and reducing errors.
Consider a Spring Boot REST API without any documentation. What is the most likely outcome for new developers trying to use it?
Think about what happens when you try to use something without instructions.
Without documentation, developers often guess how to use endpoints, which can cause errors and slow down progress.
In Spring Boot, which annotation is commonly used to add metadata for API documentation generation?
Look for the annotation related to API operation descriptions.
@ApiOperation is used with Swagger/OpenAPI to describe API endpoints for documentation.
You added Swagger to your Spring Boot app, but the UI shows no endpoints. What is the most likely cause?
Think about what enables Swagger in Spring Boot.
Swagger requires enabling via configuration like @EnableSwagger2 or OpenAPI config to scan and display endpoints.
Given this snippet using Springdoc OpenAPI:
@Operation(summary = "Get user by ID")
@GetMapping("/users/{id}")
public User getUser(@PathVariable String id) { return userService.findById(id); }What will the generated API documentation show for this endpoint's summary?
Look at the value inside the @Operation annotation.
The summary field in @Operation sets the description shown in the API docs for that endpoint.
