使用 XML 创建缓存时出现 InvalidServerSideConfigurationException
InvalidServerSideConfigurationException when creating cache using XML
我是陶土的新手。我想创建集群服务器缓存，但发现配置文件有些困难。
这是我的 tc-config-terracotta.xml 文件（我用它启动 terracotta 服务器）
<?xml version="1.0" encoding="UTF-8"?>
<tc-config xmlns="http://www.terracotta.org/config"
xmlns:ohr="http://www.terracotta.org/config/offheap-resource">
<servers>
<server host="localhost" name="clustered">
<logs>/path/log/terracotta/server-logs</logs>
</server>
</servers>
<plugins>
<config>
<ohr:offheap-resources>
<ohr:resource name="primary-server-resource" unit="MB">128
</ohr:resource>
<ohr:resource name="secondary-server-resource" unit="MB">96
</ohr:resource>
</ohr:offheap-resources>
</config>
</plugins>
</tc-config>
我使用了 ehcache-clustered-3.3.1-kit 来启动服务器。
$myPrompt/some/dir/with/ehcache/clustered/server/bin>./start-tc-server.sh -f /path/to/conf/tc-config-terracotta.xml
服务器启动没问题

异常告诉您的是缓存管理器和缓存的集群位的配置在集群知道的和客户端要求的之间有所不同。
最可能的解释是，您 运行 您的客户端代码曾经使用不同的配置，意识到存在问题或只是想更改某些内容。然后尝试 运行 客户端而不破坏集群上的缓存管理器或重新启动服务器。
您只需要重新启动服务器即可丢失所有集群状态，因为您需要不同的设置。
我已尝试在我的 IDE 中重现您的问题，复制/粘贴您的 3 个文件。
我在 intializeCache():
中发现错误
cache = cm.getCache(cacheName == null ? DEFAULT_CACHE_NAME : cacheName,
Object.class, Object.class);
触发了一个：
Exception in thread "main" java.lang.IllegalArgumentException: Cache 'myTest' type is <java.lang.String, java.lang.String>, but you retrieved it with <java.lang.Object, java.lang.Object>
at org.ehcache.core.EhcacheManager.getCache(EhcacheManager.java:162)
at MyXmlClient.intializeCache(MyXmlClient.java:48)
所以请确保您的 xml 配置与您的 Java 代码匹配：您在 XML 中使用 <String, String>，在 [=] 中使用 <String, String> 27=]代码：
cache = cm.getCache(cacheName == null ? DEFAULT_CACHE_NAME : cacheName,
String.class, String.class);
其他一切正常！

您给出的错误是由于您客户端中的 terracotta 服务器堆外资源使用与 terracotta 服务器堆外配置不匹配造成的；确保它们匹配！ （复制/粘贴他们所做的示例！）
