Quick question: Are traditional java locks ever used with spring or do you use the built in spring locks with annotations?

Quick question: Are traditional java locks ever used with spring or do you use the built in spring locks with annotations?

In Spring, traditional Java locks are typically not used as they can lead to issues with transaction management and thread safety. Instead, Spring provides built-in support for managing concurrency through annotations like @Lock and @Transactional. These annotations allow you to easily control the locking behavior of your application without having to manually implement lock management with traditional Java locks.

The @Lock annotation, for example, allows you to specify the type of lock (e.g. ReentrantLock or ReadWriteLock) and the lock mode (e.g. READ or WRITE) for a particular method or class. This makes it easier to ensure that multiple threads can safely access shared resources without causing conflicts.

Similarly, the @Transactional annotation in Spring provides transaction management capabilities that help ensure data consistency and integrity in multi-threaded environments. By annotating a method with @Transactional, you can define transaction boundaries and isolation levels to control how data is accessed and modified by concurrent threads.

Overall, while it is technically possible to use traditional Java locks in a Spring application, it is generally recommended to leverage the built-in concurrency management features provided by Spring for better performance, scalability, and thread safety.

there is no issue with using traditional java locks for traditional java actions

Alright ty

#

it's just that for some actions you need distributed locks, which can span multiple instances of your application

(which normal locks cannot do)
