Spring Boot com.hazelcast.core.HazelcastInstance IllegalStateException：无法启动节点

我正在尝试在ec2中自动发现hazelcast示例的POC。这些ec2示例将在同一个安全组中，该安全组应该能够找到hazelcast的其他节点，并且这些节点将一起形成Hazelcast的集群。当尝试在AWS示例上启动Sping Boot 应用程序时，配置文件启用AWS配置，它抛出异常：Node failed to start！
下面是代码片段：

@value("${spring.profiles.active:local}")
private String activeProfile;

@Bean
public HazelcastInstance hazelcastInstance() {
    if (activeProfile.equalsIgnoreCase("aws")) {
        Config config = new Config();
        GroupConfig groupConfig = new GroupConfig();
        groupConfig.setName("ec2-group");
        groupConfig.setPassword("ec2-password");
        config.setGroupConfig(groupConfig);

        JoinConfig joinConfig = config.getNetworkConfig().getJoin();
        joinConfig.getMulticastConfig().setEnabled(false);
        joinConfig.getTcpIpConfig().setEnabled(false);

        AwsConfig awsConfig = joinConfig.getAwsConfig();
        awsConfig.setEnabled(true);
        awsConfig.setSecurityGroupName("poc-hzcast-sg");
        awsConfig.setIamRole("my_ec2-poc-hz-role");
        awsConfig.setRegion("us-east-1");

        return Hazelcast.newHazelcastInstance(config);
    }
    return Hazelcast.newHazelcastInstance();
}

字符串
用于运行此命令的命令：

java -jar -Dspring.profiles.active=aws hazelcast-aws-poc.jar

下面是stackTrace：

确定这是由于hazelcast依赖项不匹配。hazelcast-aws 2.3与hazelcast-core版本3.10不兼容
这里有两个选项：1.使用兼容版本：

<dependency>
      <groupId>com.hazelcast</groupId>
      <artifactId>hazelcast</artifactId>
      <version>3.10.6</version>
<dependency>
    <groupId>com.hazelcast</groupId>
    <artifactId>hazelcast-aws</artifactId>
    <version>2.2</version>
</dependency>

字符串
1.使用hazelcast-all会在内部带来hazelcast-aws依赖。
参考hazelcast-aws github repo和this。

在Kubernetes集群环境中，我发现了嵌入式hazelcast的一个问题，这是由于版本不匹配。所以你必须在pom.xml或etc中对齐你的hazelcast版本依赖。如果你只需要为当前应用程序使用hazelcast，那么你只需在hazelcast.yaml中更改集群名称。

hazelcast:
 #not able join dev which is current running by other
 #application with different hazelcast version so change cluster-name from dev to dev-ptt to fix this issue
 #caused by: java.lang.illegalstateexception: node failed to start! in hazelcast embedded
 cluster-name: dev-ptt
  group:
    network:
      join:
       multicast:
        enabled: true

如果在localhost:5701上运行应用的另一个示例，也会导致此错误。
在这种情况下，除了给定的解决方法外，您可以尝试为您的应用使用另一个端口而不是5701。
