类 DefaultLockRepository

java.lang.Object

kim.sesame.framework.locks.jdbc.DefaultLockRepository

所有已实现的接口:

Closeable, AutoCloseable, LockRepository, org.springframework.beans.factory.InitializingBean

@Transactional
public class DefaultLockRepository
extends Object
implements LockRepository, org.springframework.beans.factory.InitializingBean

The default implementation of the LockRepository based on the table from the script presented in the org/springframework/integration/jdbc/schema-*.sql.

This repository can't be shared between different JdbcLockRegistry instances. Otherwise it opens a possibility to break Lock contract, where JdbcLockRegistry uses non-shared ReentrantLocks for local synchronizations.

从以下版本开始:

4.3
