elasticsearch jhipster:elasticsearch节点不可用

我正在使用jhipster（版本4.14.3）生成一个web应用程序。问题是，在生产模式下，应用程序无法连接到弹性搜索服务，该服务在端口9200上运行良好。任何帮助都将不胜感激

application-prod.yml：

data:
    elasticsearch:
        cluster-name: elasticsearch
        cluster-nodes: localhost:9300

elasticsearch.yml：

cluster.name: elasticsearch
path.data: C:\Program Files\elasticsearch-6.2.4\data
path.logs: C:\Program Files\elasticsearch-6.2.4\logs
network.host: 0.0.0.0
http.port: 9200
transport.tcp.port: 9300

例外情况详情：

org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are avail
able: [{#transport#-1}{localhost}{127.0.0.1:9300}]

这通常是版本问题。编辑jhipster项目文件夹中的src/main/docker/elasticsearch.yml，并安装相同版本的elasticsearch服务器
