Class ProblemDetail

java.lang.Object
org.springframework.http.ProblemDetail
public class ProblemDetail extends Object
Representation for an RFC 7807 problem detail. Includes spec-defined properties, and a properties map for additional, non-standard properties.

For an extended response, an application can add to the properties map. When using the Jackson library, the properties map is expanded as top level JSON properties through the ProblemDetailJacksonMixin.

For an extended response, an application can also create a subclass with additional properties. Subclasses can use the protected copy constructor to re-create an existing ProblemDetail instance as the subclass, e.g. from an @ControllerAdvice such as ResponseEntityExceptionHandler.
