Hazelcast client spring configuration

Question

I have createed a Hazelcast manager which uses spring, hibernate, jpa. I can start my hazelcast instance.

The problem I have is I dont know how to configure a hazelcast client using spring config. I want to use in some other server component a hazelcast-client

I really have no idea how to start

any help would be appreciated

Below is my spring config for hazelcast server

Answer 1

Something like this (from 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);
    }
}

Try to avoid XML, Spring is moving away from it.

Answer 2

Configured Multiple Ip's Using Pragmatically.

@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);
}

I would suggest to must read. http://docs.hazelcast.org/docs/latest/manual/html-single/index.html#configuring-client-connection-strategy
