我正在使用Infinispan 7.2.3处理Wildfly 9。Infinispan Jgroups在部署战争后崩溃
我正视与分布式缓存一个奇怪的问题：
- 在应用服务器，我有N个部署战争暴露REST服务
- 每个服务代码有共同的责任来检查CacheManager si已经存在于JNDI中，如果是的话，它使用它，否则我创建一个新的并将其绑定到JNDI。所以每场战争都会使用独特的CacheManager实例。
- Infinispan CacheManager配置为分布式模式。
infinispan和jgroups从应用程序服务器提供。 重新部署操作后，所有的战争（undploy和部署），如果我突然开始发送REST请求，这些服务我得到这个错误：

这是CacheManager中的initalization代码：
try {
ctx = new InitialContext();
cacheManager = (DefaultCacheManager)ctx.lookup(SessionConstants.CACHE_MANAGER_GLOBAL_JNDI_NAME);
} catch (NamingException e1) {
logger.error("SessionHooverJob not able to find: java:global/klopotekCacheManager ... a new instance will be created!");
}
if (cacheManager ==null){
...
configurator = ConfiguratorFactory.getStackConfigurator("default-configs/default-jgroups-udp.xml");
ProtocolConfiguration udpConfiguration = configurator.getProtocolStack().get(0);
if ("UDP".equalsIgnoreCase(udpConfiguration.getProtocolName()) && mcastAddr != null){
udpConfiguration.getProperties().put("mcast_addr", mcastAddr);
}
GlobalConfigurationBuilder gcb = new GlobalConfigurationBuilder();
gcb.globalJmxStatistics().enabled(true).allowDuplicateDomains(true);
gcb.transport().defaultTransport()
.addProperty(JGroupsTransport.CONFIGURATION_STRING, configurator.getProtocolStackString());
//.addProperty(JGroupsTransport.CONFIGURATION_FILE, "config/jgroups.xml");
ConfigurationBuilder builder = new ConfigurationBuilder();
builder.clustering().cacheMode(CacheMode.DIST_SYNC).expiration().lifespan(24l, TimeUnit.HOURS);;
cacheManager = new DefaultCacheManager(gcb.build(),
builder.build());
如果在部署后经过40-60秒左右的时间，则不会发生此问题。 如果我有一个JNDI会话管理器已经构建了jgroups通道，即使我将所有的战争解除...为什么jgroups尝试再次进行再平衡？
是否有一些配置属性设置？
为了共享缓存管理器，使用JNDI的方式写在infinispan指南（作为示例报告）上，并被其他开发人员使用。是在应用程序服务器内部署的所有战争中共享相同的cacheManager（构建大对象）的一种方法。 https://docs.jboss.org/infinispan/5.0/apidocs/org/infinispan/manager/DefaultCacheManager.html “一旦构建，CacheManagers应该可用于任何需要缓存的组件，通过JNDI或通过其他机制，如IoC容器“。 – Alex
没错，javadoc需要更新，因为JNDI确实应该用于非常特定的用例。 CDI是一种更容易处理的技术，并且比JNDI更好地处理生命周期（创建/开始/停止/销毁）。 –
所以你的回应是JNDI不能释放所有的mbean资源？ – Alex
