JHipster，如何使用 elasticsearch 设置生产环境？ (Windows 10)
JHipster, How to set up production with elasticsearch? (Windows 10)
我创建了一个新项目，正在尝试正确设置生产环境。我还没有添加任何实体，所以它仍然是一个空的 JHipster 项目！不幸的是，Elasticsearch 一直抛出异常，而且它不是开箱即用的。
异常：

已经有一个类似的问题。 Here.
建议的解决方案：
./mvnw clean
./mvnw
这是我尝试过的工作流程
docker-compose -f src\main\docker\mysql.yml up -d && docker-compose -f src\main\docker\elasticsearch.yml up -dmvnw clean && mvnw -Pprod
但不幸的是，这不起作用。还是一样的错误。
我也将 elasticseach 降级到 6.4.3 版本，但这也没有任何区别。
有没有人有什么想法？

终于找到错误了。
这真的很奇怪，因为有时一切都正常启动。仔细一看，Elasticsearch Docker 容器并不总是启动。错误代码 137！这当然使我的应用程序无法连接到 ES。
我增加了 Docker 的资源（描述 here）。现在一切正常 运行！
我创建了一个新项目，正在尝试正确设置生产环境。我还没有添加任何实体，所以它仍然是一个空的 JHipster 项目！不幸的是，Elasticsearch 一直抛出异常，而且它不是开箱即用的。
