ISPN000217，同时将数据添加到infinispan缓存中

Question

我有一个应用程序在2个群集内的4个节点上运行。该应用程序已使用infinispan和SpringEmbeddedCacheManager配置了缓存。尝试将数据添加到缓存时遇到间歇性问题，请注意，我正在将数据添加为键值对，其中我的值将始终是自定义类。

我只是试图将缓存类型更改为复制，本地和无效，我发现使用本地或无效缓存时没有问题。任何人都可以确认分布式缓存中的大对象是否引起任何问题。

Infinispan配置

<distributed-cache name="apigw-access-cache" owners="1" segments="20" mode="SYNC" statistics="false">
    <eviction max-entries="10" strategy="LIRS"/>
    <expiration max-idle="360000" lifespan="3600000"/>
</distributed-cache>

Infinispan版本

   <dependency>
            <groupId>org.infinispan</groupId>
            <artifactId>infinispan-spring4</artifactId>
            <version>7.0.3.Final</version><!--$NO-MVN-MAN-VER$ -->
        </dependency>

Answer 1

首先，您不应该使用Infinispan的旧版本，应该升级到9.4.17.Final。>

[堆栈跟踪片段似乎没有正确的顺序，但是Can not set java.util.Set field Class.field to java.lang.String是因为您的两个节点具有相同类的不同版本。

分布式缓存和失效缓存之间的最大区别是，分布式缓存将值复制到其他节点，而失效缓存则发送仅包含密钥的失效消息。如果失效缓存有效，则问题几乎可以肯定是您的一个值类已更改，并且其中一个节点仍具有旧版本。
