Spring boot auto configuration overriding custom (elasticsearchTemplate) configuration

Question

I have created the following configuration (I duplicated the @Lazy because I was not able to make it work)

@Lazy(true)
@Configuration
public class ElasticConfiguration
{
   private Logger logger = LoggerFactory.getLogger(ElasticConfiguration.class);

   @Value("${elasticsearch.host}")
   private String esHost;

   @Value("${elasticsearch.port}")
   private int esPort;

   @Value("${elasticsearch.clustername}")
   private String esClusterName;

   @Lazy(true)
   @Bean
   public Client client() throws Exception
   {
      Builder builder = Settings.builder();
      // builder.put("client.transport.sniff", true);
      Settings settings = builder.put("cluster.name", esClusterName).build();
      TransportClient client = new PreBuiltTransportClient(settings);
      InetAddress adress = InetAddress.getByName(esHost);
      client.addTransportAddress(new InetSocketTransportAddress(adress, esPort));
      logger.debug(
         "ES Client built with cluster.name;" + esClusterName + ";host;" + esHost + ";port;" + esPort + ";client.transport.sniff;"
            + builder.get("client.transport.sniff"));
      return client;
   }

   @Lazy(true)
   @Bean
   public ElasticsearchOperations elasticsearchTemplate() throws Exception
   {
      return new ElasticsearchTemplate(client());
   }
}

I am not able to have the lazy initialization because it seems my configuration is overriden by spring-boot auto configuration

Overriding bean definition for bean 'elasticsearchTemplate' with a different definition: replacing [Root bean: class [null]; scope=; abstract=false; lazyInit=true; autowireMode=3; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=elasticConfiguration; factoryMethodName=elasticsearchTemplate; initMethodName=null; destroyMethodName=(inferred); defined in class path resource [xxx/xxx/ElasticConfiguration.class]] with [Root bean: class [null]; scope=; abstract=false; lazyInit=false; autowireMode=3; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=org.springframework.boot.autoconfigure.data.elasticsearch.ElasticsearchDataAutoConfiguration; factoryMethodName=elasticsearchTemplate; initMethodName=null; destroyMethodName=(inferred); defined in class path resource [org/springframework/boot/autoconfigure/data/elasticsearch/ElasticsearchDataAutoConfiguration.class]]

I also tried to add the following annotation on the class

@AutoConfigureOrder(Ordered.HIGHEST_PRECEDENCE)

in association with the following property, but it did not work better

org.springframework.boot.autoconfigure.EnableAutoConfiguration=xxx.xxx.ElasticConfiguration

What should I do ?

Ok so the only solution I found was to use the following property

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.data.elasticsearch.ElasticsearchDataAutoConfiguration

Note that using the folling annotation did not work for me ...

@EnableAutoConfiguration(exclude={ElasticsearchDataAutoConfiguration.class})

EDIT

In fact my problem was that my method elasticsearchTemplate() was returning ElasticsearchOperations instead of ElasticsearchTemplate.

When changing the signature the @Lazy annotation seems to work.
