The best way to handle type-safe responses with RestClient is using ParameterizedTypeReference. This approach ensures accurate generic type mapping during your Spring Boot 3.2+ migration, preserving the type safety previously handled by RestTemplate responses.

Yes, RestClient supports modern error handling patterns to replace RestTemplate implementations. The migration process specifically addresses updating error handling across services while upgrading HTTP client code paths to the fluent RestClient interface in Spring Boot 3.2+.

Common pitfalls when upgrading to RestClient include incorrect bean configuration and improper migration of error handling. The migration process highlights configuration patterns for RestClient beans and common pitfalls to avoid when upgrading to Spring Boot 3.2+.

Spring Boot 3.2 migration requires updating RestTemplate methods for GET, POST, and DELETE operations. The migration targets legacy HTTP client code paths across services, ensuring proper configuration and type-safe responses using ParameterizedTypeReference.
