如何使用spring data reactive mongodb transactionalOperator限制事务范围

@Transactional
public Mono<Void> performTransaction() {
    // 在这里执行需要进行事务管理的操作
    // ...
}

@Transactional
public Mono<Void> performTransaction(TransactionalOperator transactionalOperator) {
    return transactionalOperator.execute(status -> {
        // 在这里执行需要进行事务管理的操作
        // ...
        return Mono.empty();
    });
}

@Transactional
public Mono<Void> performTransaction(TransactionalOperator transactionalOperator, ReactiveMongoTemplate reactiveMongoTemplate) {
    return transactionalOperator.execute(status -> {
        Mono<Void> saveOperation = reactiveMongoTemplate.save(newDocument);
        Mono<Void> deleteOperation = reactiveMongoTemplate.remove(query, collectionName);
        
        return Mono.when(saveOperation, deleteOperation);
    });
}
