我正在运行带有1个服务器和2个客户端的Ignite v2.1。客户端在Tomcat服务器上运行并使用IgniteSpringBean。
两个客户端都使用相同的IgniteAtomicLong。当一个客户端从网格中删除时，当另一个客户端尝试使用AtomicLong时，它会抛出以下异常：
class org.apache.ignite.IgniteException: Failed to find atomic long: MY_ATOMIC_LONG
at org.apache.ignite.internal.processors.datastructures.GridCacheAtomicLongImpl.getAndIncrement(GridCacheAtomicLongImpl.java:153)
（我没有看到IgniteAtomicSequence的这种行为）
以下是上面列出的例外情况：
java.lang.IllegalStateException: Atomic long was removed from cache: MY_ATOMIC_LONG
at org.apache.ignite.internal.processors.datastructures.GridCacheAtomicLongImpl.removedError(GridCacheAtomicLongImpl.java:328)
at org.apache.ignite.internal.processors.datastructures.GridCacheAtomicLongImpl.checkRemoved(GridCacheAtomicLongImpl.java:304)
at org.apache.ignite.internal.processors.datastructures.GridCacheAtomicLongImpl.getAndIncrement(GridCacheAtomicLongImpl.java:143)
这是服务器配置：

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="

似乎，您在客户端节点上调用IgniteAtomicLong #close方法。在这种情况下，实例将关闭，并且在群集中的其他节点上不可用。
答案 1 :(得分：0)
最有可能被调用IgniteAtomicLong #close方法。它不是必须由您直接调用，可以调用它，因为它实现了Closeable接口，例如：
尝试（IgniteAtomicLong atomicLong = ignite.atomicLong（name，1，true））{}
因此，建议不要将IgniteAtomicLong添加到Spring上下文
