今天遇到的问题是在响应式编程中发生禁止block
异常:
org.springframework.statemachine.persist.AbstractStateMachinePersister#restore
源码如下:
@Override
public final StateMachine<S, E> restore(StateMachine<S, E> stateMachine, T contextObj) throws Exception {
final StateMachineContext<S, E> context = stateMachinePersist.read(contextObj);
stateMachine.stopReactively().block();
stateMachine.getStateMachineAccessor().doWithAllRegions(function -> function.resetStateMachineReactively(context).block());
stateMachine.startReactively().block();
return stateMachine;
}
自己重新编写该功能
public Mono<StateMachine<StateEnum, WordChain>> restore(StateMachine<WordChainStateEnuminEventEnum> stateMaring contextObj) {
return stateMachine.stopReactively().then(Mono.fromSupplier((SerSupp<StateMachineContext<WordChainStateEnum, WordChainEventEn ateMachineRuntimePersister.read(contextObj))).flatMapMany(context ->
Flux.fromIterable(stateMachine.getStateMachineAccessor().withAllRegions())
.flatMap(function -> function.resetStateMachineReactively(context)))
.then(stateMachine.startReactively()).thenReturn(stateMachine);
}
