環境は  
Spring4.2  
SpringDataElasticsearch  
Java1.8  
です。

ESサーバーはAWS/Redhat7で、localhostの9200をポートフォワードして接続しています。  
※xinetdやfirewall, SELinux, セキュリティーグループも確認しましたが、直接接続がなぜかできないため、ポートフォワードしました。

接続確認として、JUnitでテストしています。

<http://localhost:9200/> で接続も確認しました。

```

    @Configuration
    @PropertySource("classpath:esearch.properties")
    @EnableTransactionManagement
    @EnableElasticsearchRepositories(basePackages={"com.aaa.repository"})
    public class EsConfig {
    
        @Resource
        private Environment env;
    
        private static final String ESEARCH_PORT = "esearch.port";
        private static final String ESEARCH_HOST = "esearch.host";
    
        @Bean
        public ElasticsearchOperations elasticsearchTemplate() throws Exception{
            return new ElasticsearchTemplate(client());
        }
    
        @Bean
        public Client client() throws Exception{
            return new TransportClient()
                        .addTransportAddress(new InetSocketTransportAddress("localhost", 9200));
        }
    }
    
```

TESTCASE

```

    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration(classes={EsConfig.class})
    public class EsRepositoryTest {
        @Autowired
        private TestRepository testRepository;
    
        @Test
        public void test_FIND() throws Exception {
            Iterable<Test> test = testRepository.findAll();
        }
    }
    
```

設定に不備があるのでしょうか？

question
spring java8 elasticsearch junit
JavaからElasticSearchに接続できない
TransportClient が利用するポートは、9300 であるような気がします。

<https://www.elastic.co/guide/en/elasticsearch/client/java-
api/current/transport-client.html>

Elasticsearch は、 http 用(9200)と Transport 用(9300)の2つの 通信ポートを用意していたはず。
