Question

我正在使用hazelcast：

spring-integration-hazelcast:1.0.0.RELEASE
hazelcast-all:3.12.4
有关gradle的详细信息，请参见[1]

一切正常：）

由于遇到了一些问题，我试图更新到最新版本，所以：

hazelcast 3.12.6
和spring-integration-hazelcast 2.0.0.RELEASE

但是我的应用程序甚至没有启动，我得到了：

但是为什么呢？ :-(“问题”不是hazelcast 3.12.6，因为它可以正常工作 spring-integration-hazelcast 1.0.0.RELEASE。但是从spring-integration-hazelcast 1.0.0.RELEASE更改为2.0.0.RELEASE会触发此错误。

  implementation ("org.springframework.boot:spring-boot-starter-web:2.2.5.RELEASE") 
  implementation ("org.springframework.integration:spring-integration-hazelcast:1.0.0.RELEASE")
  implementation "com.hazelcast:hazelcast-all:3.12.4"
  compile group: 'org.springframework.integration', name: 'spring-integration-core', version: '5.2.1.RELEASE'

问题是spring-integration模块使用Hazelcast CP Subsystem（在CPSubsystemImpl.getLock()中），该模块在Hazelcast中默认为禁用。

您可以使用以下Hazelcast配置启用它：

@Bean
HazelcastInstance hazelcastInstance() {
    Config config = new Config();
    config.getCPSubsystemConfig().setCPMemberCount(3);
    return Hazelcast.newHazelcastInstance(config);
}

请注意，您的群集中至少应有3个Hazelcast成员。

未启用CP子系统
