Springboot2.0.4集成ElasticSearch6，启动项目报错，无法注入TransportClient

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transportClient' defined in class path resource [com/xunwu/config/ElasticSearchConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.elasticsearch.client.transport.TransportClient]: Factory method 'transportClient' threw exception; nested exception is java.lang.IllegalStateException: availableProcessors is already set to [4], rejecting [4]
 
以下是TransportClient代码

    @Bean

    public TransportClient transportClient() {



        logger.info("初始化开始。。。。。");



        TransportClient client = null;

        

        TransportAddress master = null;



        try {

            master = new TransportAddress(

                    InetAddress.getByName("127.0.0.1"), Integer.valueOf(9300));

            Settings settings = Settings.builder()

                    // 集群的名称

                    .put("cluster.name", "search")

                    // 自动发现节点

                    .put("client.transport.sniff", true)

                    .build();



            client = new PreBuiltTransportClient(settings)

                    .addTransportAddress(master);

        } catch(UnknownHostException e){

            e.printStackTrace();

            logger.info("初始化bean失败");

        }



        return client;

    }

在单元测试的时候是可以获取到这个连接的

@Autowired

private TransportClient client;



@Test

public void contextLoads() {



    System.out.println(client);



}

就是启动SpringBoot的时候无法启动，无法注入TransportClient这个Bean。
 
依赖如下，目前使用的是6.1.3，更换了6.2.4版本也没有作用，因为本机使用的6版本，所以没有使用5版本及以下的依赖，求大神解答

<elasticsearch.version>6.1.3</elasticsearch.version>
