java - 如何从 Java 应用程序中运行 elasticsearch 5.1 服务器(不通过命令行)

Question

在elasticsearch 1.x中，我曾经调用:

org.elasticsearch.bootstrap.Elasticsearch.main(args)

但是在 5.x 中，他们将 org.elasticsearch.bootstrap.Elasticsearch 类设为包私有(private)(默认)，因此我无法再以简洁的方式从 java 代码运行 ES 服务器。有没有其他简洁的方法来做到这一点(与 Runtime exec 或 Apache Commons Exec 不同)？

谢谢!

Answer 1

你不能。不支持。

Embedded Elasticsearch not supported

Some users run Elasticsearch as embedded. We are not going to stop them from doing so, but we cannot support it. Embedding Elasticsearch bypasses the security manager, the Jar Hell checks, the bootstrap checks, and plugin loading. It is inherently unsafe and not recommended for production. For the sanity of our developers and support team, we cannot support users who disable all of the safety mechanisms which we have added for good reasons. For the same reason, we will not accept pull requests or make changes specifically to support the embedded use case
