spring-boot - Spring Boot @Transaction(timeout = 1)

Question

我正在使用 spring-boot-starter-data-jpa从 Spring Boot 1.5.6

例如，当事务超时大于 1 时，一切正常@Transaction(timeout = 2) , @Transaction(timeout = 5) , 或 @Transaction(timeout = 10) ,
但是当我将它设置为 @Transaction(timeout = 1)它会在不到一秒的时间内抛出异常。这是我的代码的快照:

@Transactional(readOnly=true)
public interface IUserRepository extends CrudRepository<UserEntity,Long>{
     @Transactional(timeout = 1)
     Iterable<UserEntity> findAll();

异常(exception)是:

15:18:11.078 [http-nio-9999-exec-2] ERROR [o.a.c.c.C.[.[.[.[dispatcherServlet]:181] - Servlet.service() for servlet [dispatcherServlet] in context with path [/springJPA-LOCAL] threw exception [Request processing failed; nested exception is org.springframework.orm.jpa.JpaSystemException: nested exception is javax.persistence.PersistenceException] with root cause

Answer 1

我发现决定hibernate的事务超时的逻辑有问题。因此，刚刚提出了以下问题。
https://hibernate.atlassian.net/browse/HHH-14062?atlOrigin=eyJpIjoiNTBhZTgzODBmYTFjNDU2MDhhYzM4NjU3ZjFiYzY5NjAiLCJwIjoiaiJ9

我要直接发 PR 来修复它。我不知道它什么时候会改变，但如果 Hibernate 团队确定该错误是正确的，我认为它会很快修复。
