Question

我正在努力让一个小型Hazelcast集群与简单的JCache兼容客户端合作。不幸的是，我得到了例外：＆＃34; java.lang.IllegalArgumentException：没有使用名称注册的服务：hz：impl：cacheService＆＃34;。我很感激如何解决这个问题。

我使用的是Hazelcast版本3.4（与3.3和3.4-EA有相同的行为）。

以下是来自hazelcast-client.xml的代码段：

<group>
    <name>group1</name>
</group>

<network>
    <cluster-members>
        <address>192.168.56.10:5701</address>
        <address>192.168.56.20:5701</address>
    </cluster-members>
</network>

Answer 1

服务器端的激活缓存？：）

所有需要的是将cache-api-1.0.0.jar添加到Hazelcast节点的类路径中。

Answer 2

我在 OSGi 上下文中收到了相同的错误消息。 cache-api在类路径上（我前往使用'org.apache.servicemix.bundles:org.apache.servicemix.bundles.javax-cache-api:1.0.0_1'，因为在其他lib中缺少导出）。

问题是，错误的ClassLoader用于检查JCache是否在类路径上。因此，我必须像这样初始化Hazelcast实例：

ClassLoader hazelClassLoader = hazelcastOSGiService.getOwnerBundle().adapt(BundleWiring.class).getClassLoader();
Config config = new Config();
// set the classloader that is used by hazelcast to check for JCache Classes
config.setClassLoader(hazelClassLoader);

// Create a HazelcastInstance
hazelcastInstance = hazelcastOSGiService.newHazelcastInstance(config);

尝试使Hazelcast集群与JCache兼容的客户端一起工作时出现异常
