You are tasked with developing a Spring Boot application that integrates with multiple external APIs. How would you implement exception handling to manage failures and ensure that informative error messages are relayed back to the user?
- Implement a retry mechanism for API calls, and return HTTP status codes along with descriptive error messages in the response.
- Log all exceptions internally without providing any error messages to the user.
- Return generic error messages without any HTTP status codes to avoid exposing internal details.
- Implement a global exception handler that returns standardized error responses with clear error messages and appropriate HTTP status codes.
When integrating with external APIs in a Spring Boot application, it's crucial to implement a global exception handler (Option 4) to manage failures. This handler should return standardized error responses with clear error messages and appropriate HTTP status codes, ensuring informative messages are relayed back to the user. Implementing a retry mechanism (Option 1) is a good practice, but it should be combined with proper error handling. Options 2 and 3 are not recommended as they either log errors internally or provide generic and uninformative error messages to users.
