@AccessTimeout(value = 0) 和@Lock(LockType.WRITE) 的区别
Differences between @AccessTimeout(value = 0) and @Lock(LockType.WRITE)
正如我在 中读到的 Java 7 EE:
@Lock(LockType.WRITE): A method associated with an exclusive lock will
not allow concurrent invocations until the method’s processing is
completed.
An @AccessTimeoutvalue of 0 indicates that concurrent access is not
allowed. This will result in throwing a ConcurrentAccessExceptionif a
client invokes a method that is currently being used.
所以...有什么区别？这两个注解都禁用并发调用，我看不出它们之间有什么区别。有什么情况可以一起使用它们吗？
第一种方法将阻塞后续调用者，直到当前调用者完成调用。第二，如果同时有多个调用，@AccessTimeoutvalue 将抛出异常。差别很大。
