弹簧状态机拦截器不起作用

Question

stateMachine.getStateMachineAccessor()
                .doWithRegion(function -> function.addStateMachineInterceptor(
                        new StateMachineInterceptorAdapter<CandidacyStates, CandidacyEvents>() {
                            @Override
                            public Exception stateMachineError(StateMachine<CandidacyStates, CandidacyEvents> stateMachine12,
                                                               Exception exception) {
                                // return null indicating handled error
                                return exception;
                            }
                        }));

我创建了拦截器来处理错误 但是当我们从未接受的事件中抛出异常时，我看不到调用进入StateStateMachineFunction的调用
