Wildfly 10 Infinispan TreeCache无法正常工作

Question

我正在从Wildfly 8.2迁移到10.1不幸的是，我遇到了Infinispan TreeCache的问题。

以下是几个问题：

1. Wildfly 10配置不再支持调用批处理

这是我的配置：

<subsystem xmlns="urn:jboss:domain:infinispan:4.0">
...
  <cache-container name="my_container" default-cache="my_tree_cache" jndi-name="java:jboss/my_container">
      <transport lock-timeout="60000"/>
      <local-cache name="my_cache"/> 
      <local-cache name="my_tree_cache" batching="true"/> 
  </cache-container>
</subsystem>

启动时出错：

> Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[345,17] 
> Message: WFLYCTL0197: Unexpected attribute 'batching' encountered

2. 如果我删除“批处理”属性。我收到此错误：

com.daiwacm.modjsf.dataaccess.DataException: getTreeCache has failed for jndi value (my_tree_cache)
Caused by: org.infinispan.commons.CacheConfigurationException: invocationBatching is not 
enabled for cache 'my_tree_cache'. Make sure this is enabled by calling configurationBuilder.invocationBatching().enable()

3. 如果我以编程方式设置批处理：

Context context = new InitialContext();
CacheContainer cacheContainer = (CacheContainer) context.lookup(jndiName);
TreeCacheFactory tcf = new TreeCacheFactory();
Cache cache = cacheContainer.getCache(cacheName);
cache.getCacheManager().defineConfiguration(cacheName, 
     new ConfigurationBuilder().read(cache.getCacheConfiguration()).invocationBatching().enable().build());
TreeCache treeCache = tcf.createTreeCache(cache);

我收到此错误：

> Caused by: org.infinispan.commons.CacheConfigurationException:
> ISPN000381: This configuration is not supported for simple cache
>         at org.infinispan.configuration.cache.ConfigurationBuilder.validateSimpleCacheConfiguration(ConfigurationBuilder.java:219)

> ...

Answer 1

不要以编程方式设置配置;我不确定这是一种有效的方法，尽管它似乎很有效。

您正在寻找的配置选项是

<local-cache name="my_cache"> 
    <transaction transaction-mode="BATCH" />
</local-cache>

（如果您有任何疑问，请参考docs/schema/jboss-as-infinispan_4_0.xsd的架构）

最后一个问题是，对于本地缓存，WF会在可能的情况下自动启用某些优化。以编程方式重新定义缓存时，将设置此优化（简单缓存）。所以你必须设置

new ConfigurationBuilder().read(cache.getCacheConfiguration())
    .simpleCache(false)
    .invocationBatching().enable()
