Quarkus还不允许全局配置默认事务超时（请参见https://github.com/quarkusio/Quarkus/pull/2984)。

但您应该能够在用户事务级别执行此操作。

您可以在postconstruct块中注入UserTransaction对象并设置事务超时。

@ApplicationScoped
class MyScheduler {

    @Inject UserTransaction userTransaction;

    @PostConstruct
    fun init() {
        //set a timeout as high as you need
        userTransaction.setTransactionTimeout(3600);
    }

    @Transactional
    @Scheduled(every = "7200s")
    open fun process() {
        entityManager.persist(myObject)

    }
}
