Question

使用hazelcast 3.6：

运行此异常后

java.lang.IllegalArgumentException：无法创建ObjectName 在 com.hazelcast.jmx.HazelcastMBean.setObjectName（HazelcastMBean.java:116）在 com.hazelcast.jmx.ConnectionManagerMBean。（ConnectionManagerMBean.java:39）在 com.hazelcast.jmx.InstanceMBean.createMBeans（InstanceMBean.java:74）在com.hazelcast.jmx.InstanceMBean。（InstanceMBean.java：67）at com.hazelcast.jmx.ManagementService。（ManagementService.java:67）在 com.hazelcast.instance.HazelcastInstanceImpl。（HazelcastInstanceImpl.java:136）在 com.hazelcast.instance.HazelcastInstanceFactory.constructHazelcastInstance（HazelcastInstanceFactory.java:160）在 com.hazelcast.instance.HazelcastInstanceFactory.getOrCreateHazelcastInstance（HazelcastInstanceFactory.java:98）在 com.hazelcast.cache.impl.HazelcastServerCachingProvider.getOrCreateInstance（HazelcastServerCachingProvider.java:98）在 com.hazelcast.cache.impl.HazelcastServerCachingProvider.createHazelcastCacheManager（HazelcastServerCachingProvider.java:64）在 com.hazelcast.cache.impl.HazelcastServerCachingProvider.createHazelcastCacheManager（HazelcastServerCachingProvider.java:42）在 com.hazelcast.cache.impl.AbstractHazelcastCachingProvider.getCacheManager（AbstractHazelcastCachingProvider.java:94）在 com.hazelcast.cache.HazelcastCachingProvider.getCacheManager（HazelcastCachingProvider.java:131）

我在File：HazelcastServerCachingProvider.java（从第78行开始）看了这部分导致错误的代码：

String location = properties.getProperty(HazelcastCachingProvider.HAZELCAST_CONFIG_LOCATION);
// If config location is specified, get instance through it.
if (location != null) {
    URI uri = new URI(location);
    String scheme = uri.getScheme();
    if (scheme == null) {
            // It is a place holder
            uri = new URI(System.getProperty(uri.getRawSchemeSpecificPart()));
    }
    ClassLoader theClassLoader = classLoader == null ? getDefaultClassLoader() : classLoader;
    final URL configURL;
    if ("classpath".equals(scheme)) {
            configURL = theClassLoader.getResource(uri.getRawSchemeSpecificPart());
    } else if ("file".equals(scheme) || "http".equals(scheme) || "https".equals(scheme)) {
            configURL = uri.toURL();
    } else {
            throw new URISyntaxException(location, "Unsupported protocol in configuration location URL");
    }
    try {
            Config config = new XmlConfigBuilder(configURL).build();
            config.setClassLoader(theClassLoader);

            **HERE BAD INSTANCENAME IS GENERATED**
            config.setInstanceName(configURL.toString());
            return HazelcastInstanceFactory.getOrCreateHazelcastInstance(config);
    } catch (Exception e) {
            throw ExceptionUtil.rethrow(e);
    }
}

在传递的hazelcast_config_location中使用文件或http（s）协议时，我们将无法创建mbean，因为hazelCastInstanceName不应包含字符'：'，这很可能是configURI名称的一部分。

这是一个Bug还是我忽略了什么？

感谢您的回复

javax ObjectName类不支持字符:并抛出MalformedObjectNameException。 Hazelcast处理此异常并抛出IllegalArgumentException来自它的消息。

https://github.com/hazelcast/hazelcast/blob/master/hazelcast/src/main/java/com/hazelcast/internal/jmx/HazelcastMBean.java#L121

https://docs.oracle.com/javase/7/docs/api/javax/management/ObjectName.html

编辑：quote函数应该在你的情况下处理它，但是，hz中有一个错误显然。请参阅：https://github.com/hazelcast/hazelcast/blob/master/hazelcast/src/main/java/com/hazelcast/internal/jmx/ConnectionManagerMBean.java#L38

使用文件| http（s）协议时，Hazelcast无法创建ObjectName
