Question

我创建了一个使用spring，hibernate，jpa的Hazelcast管理器。我可以开始我的hazelcast实例。

我遇到的问题是我不知道如何使用spring config配置hazelcast客户端。我想在其他服务器组件中使用hazelcast-client

我真的不知道如何开始

任何帮助将不胜感激

以下是我对hazelcast服务器的弹簧配置

Answer 1

配置多个Ip实用地使用。

@Bean
public ClientConfig clientConfig() {
  ClientConfig clientConfig = new ClientConfig();
  ClientNetworkConfig networkConfig = clientConfig.getNetworkConfig();
  networkConfig.addAddress("172.17.0.4:5701", "172.17.0.6:5701")
    .setSmartRouting(true)
    .addOutboundPortDefinition("34700-34710")
    .setRedoOperation(true)
    .setConnectionTimeout(5000)
    .setConnectionAttemptLimit(5);

  return clientConfig;

}

@Bean
public HazelcastInstance hazelcastInstance(ClientConfig clientConfig) {
  return HazelcastClient.newHazelcastClient(clientConfig);
}

我建议必须阅读。 http://docs.hazelcast.org/docs/latest/manual/html-single/index.html#configuring-client-connection-strategy

Answer 2

像这样（来自https://github.com/neilstevenson/spring-boot-autoconfigure-test/tree/master/hazelcast-imdg-client）

@Configuration
@ConditionalOnMissingBean(ClientConfig.class)
static class HazelcastClientConfigConfiguration {

    @Bean
    public ClientConfig clientConfig() throws Exception {
            return new XmlClientConfigBuilder().build();
    }
}

@Configuration
@ConditionalOnMissingBean(HazelcastInstance.class)
static class HazelcastClientConfiguration {

    @Bean
    public HazelcastInstance hazelcastInstance(ClientConfig clientConfig) {
        return HazelcastClient.newHazelcastClient(clientConfig);
    }
}

尽量避免使用XML，Spring正在逐渐远离它。
