Interface DispatchExceptionHandler

All Known Implementing Classes:

public interface DispatchExceptionHandler
Contract to map a Throwable to a HandlerResult.

Supported by DispatcherHandler when used in the following ways:

  • Set on a HandlerResult, allowing a HandlerAdapter to apply its exception handling to deferred exceptions from asynchronous return values, and to response rendering.
  • Implemented by a HandlerAdapter in order to handle exceptions that occur before a request is mapped to a handler, or for unhandled errors from a handler.
