logstash报错

[logstash.outputs.elasticsearch][main] Attempted to resurrect connection to dead ES instance, but got an error {:url=>"http://127.0.0.1:9200/", :exception=>LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError, :message=>"Elasticsearch Unreachable: [http://127.0.0.1:9200/][Manticore::SocketException] Connection refused (Connection refused)"}

logstash-springboot.conf的output-->hosts，要配置成实际的ip，如xxx.xxx.xxx.xxx:9200，不能配置127.0.0.1:9200或者localhost:9200，否则会报Connection refused错误
