Java Hazelcast TargetNotMemberException:不是成员！目标

我看过很多关于a

com.hazelcast.spi.exception.TargetNotMemberException的帖子：不是会员！目标：

但在这种情况下该怎么办呢？问题：是否可以捕获异常并执行“hazelCastInstance.shutdown（）`”

还可以在“错误节点”中连续看到：“队列中剩余的迁移任务=>1”

Hazelcast 3.7群集具有两个节点

完整堆栈跟踪：

TargetNotMemberException扩展了RetryableHazelcastException，它进一步扩展了HazelcastException，因此您可以捕获HazelcastException然后关闭实例，也可以直接捕获TargetNotMemberException并关闭Hazelcast实例。你可以在课下调查

你可以这样编码

import java.io.PrintWriter;
import java.io.StringWriter;

import com.hazelcast.config.Config;
import com.hazelcast.core.Hazelcast;
import com.hazelcast.core.HazelcastException;
import com.hazelcast.core.HazelcastInstance;
import com.hazelcast.spi.exception.TargetNotMemberException;

public class HazelcastExceptionTest {
    public static void main(String[] args) {
        Config config = new Config("instanceOne");
        HazelcastInstance instanceOne = Hazelcast.newHazelcastInstance(config);

        try {
            testTargetNotMemberException();
        }
        catch (HazelcastException e) {
            StringWriter trace = new StringWriter();
            PrintWriter eTrace = new PrintWriter(trace, true);
            e.printStackTrace(eTrace);
            System.out.println("exception " + trace.toString());
            instanceOne.shutdown();

        }
    }

    public static void testTargetNotMemberException() {
        throw new TargetNotMemberException("TargetNotMemberException");
    }
}
