In java spring hibernate 3.6.3 如何告诉方法等待锁被获取以及如何重试失败的事务？

Question

In my spring application I am facing failed to acquire lock issue and transaction is getting failed. It is not even rollbacking the transaction as database is not providing the lock. How to tell a method to wait until the lock is acquired? I am using hibernate and mysql.

First of all, you have to use @Transactional as method/class annotation in the case of spring.

By default, we have the propagation REQUIRED @Transactional(propagation = Propagation.REQUIRED) . Spring checks if there is an active transaction, then it creates a new one if nothing existed. Here you can find the explanation of spring transaction propagations.

First, you have to take a look and analyze what you need there to use.

Please tell us, where do you face with lock issues? Probably you have to deal with the Isolation levels; We can deal with them at mySql, hibernate or spring level. Here we need to know where you have configurations for isolation (mySql, hibernate or spring).

You can check if you need to update the lock timeout , using QueryHints .

@QueryHints({@QueryHint(name = "javax.persistence.lock.timeout", value = "3000")})
public Optional<Customer> findById(Long customerId);
