ElasticSearch地址没有配置

• 异常描述

1 2	Cannot resolve reference to bean 'elasticsearchTemplate' while setting bean property 'elasticsearchOperations'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'elasticsearchTemplate' available

  application.properties(yml)增加配置

• 异常描述

1 2	Failed to instantiate [org.elasticsearch.client.transport.TransportClient]: Factory method 'elasticsearchClient' threw exception; nested exception is java.lang.IllegalStateException: availableProcessors is already set to [4], rejecting [4]

  两个地方增加配置参数
  Spring Boot 启动类增加配置参数，增加后启动服务不报错。
