Question

尝试重新启动无法启动的CacheManager时，我收到此异常。

引起：org.infinispan.jmx.JmxDomainConflictException：ISPN000034：已经在'org.infinispan'JMX域下注册了JMX MBean实例type = CacheManager，name =“DefaultCacheManager”。如果要允许多个实例配置相同的JMX域，请在'globalJmxStatistics'配置元素中启用'allowDuplicateDomains'属性在org.infinispan.jmx.JmxUtil.buildJmxDomain（JmxUtil.java:53）

我认为这是一个错误，但我是否正确？

使用的版本是9.0.0.Final。

修改

使用此代码段可以看到错误。

import org.infinispan.configuration.cache.*;
import org.infinispan.configuration.global.*;
import org.infinispan.manager.*;

class Main {

    public static void main(String[] args) {
        System.out.println("Starting");
        GlobalConfigurationBuilder global = GlobalConfigurationBuilder.defaultClusteredBuilder();
        global.transport()
            .clusterName("discover-service-poc")
            .initialClusterSize(3);

        ConfigurationBuilder builder = new ConfigurationBuilder();
        builder.clustering().cacheMode(CacheMode.REPL_SYNC);
        DefaultCacheManager cacheManager = new DefaultCacheManager(global.build(), builder.build(), false);

        try {
            System.out.println("Starting cacheManger first time.");
            cacheManager.start();
        } catch (Exception e) {
            e.printStackTrace();
            cacheManager.stop();
        }


        try {
            System.out.println("Starting cacheManger second time.");
            System.out.println("startAllowed: " + cacheManager.getStatus().startAllowed());
            cacheManager.start();
            System.out.println("Nothing happening because in failed state");
            System.out.println("startAllowed: " + cacheManager.getStatus().startAllowed());
        } catch (Exception e) {
            e.printStackTrace();
            cacheManager.stop();
        }

        cacheManager = new DefaultCacheManager(global.build(), builder.build(), false);
        cacheManager.start();
    }

}
