我知道这个问题已经得到解决，但我已经尽了一切努力，无法解决我的问题。
我刚刚安装并启动了 elasticsearch。这是弹性的日志:

因此，Elastic 正在完全运行并监听端口 9300。
我的集群名称是“my-application”。
通过 elasticsearch.yml 确认:
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: my-application
#
并通过请求确认 http://localhost:9200/ :
{
"name" : "xhkU1rX",
"cluster_name" : "my-application",
"cluster_uuid" : "ygmbc6k0TpKdJP77OJeG9g",
"version" : {
"number" : "5.4.0",
"build_hash" : "780f8c4",
"build_date" : "2017-04-28T17:43:27.229Z",
"build_snapshot" : false,
"lucene_version" : "6.5.0"
},
"tagline" : "You Know, for Search"
}
这是我的 Maven 依赖项(elastic 和客户端的版本是一致的):
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>transport</artifactId>
<version>5.4.0</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>

</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.21</version>
</dependency>
这是我的 java 代码:
import java.net.InetAddress;
import java.net.UnknownHostException;
import java.util.Collections;
import org.elasticsearch.action.search.SearchResponse;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.elasticsearch.transport.client.PreBuiltTransportClient;
public class Test {
public static void main(String[] args) throws UnknownHostException {
Settings clusterSettings = Settings.builder()
.put("cluster.name", "my-application")
.build();
TransportClient transportClient = new PreBuiltTransportClient(clusterSettings)
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"), 9300));
try {
SearchResponse response = transportClient
.prepareSearch()
.execute().actionGet();
System.out.println(response.toString());
} catch (Exception e) {
e.printStackTrace();
} finally {
transportClient.close();
}
}
}
这给了我以下日志:

如果我尝试在终端上执行此命令:

系统提示我只能输入 6 个(不可见的)字符和弹性控制台显示(我输入了 azerty):

说明9300端口是好的。
我不明白我做错了什么。
有人能帮帮我吗？

我有一个在Linux服务器上运行的ruby脚本。它不使用rails或任何东西。它基本上是一个命令行ruby脚本，可以像这样传递参数:./ruby_script.rbarg1arg2如何将参数抽象到配置文件(例如yaml文件或其他文件)中？您能否举例说明如何做到这一点？提前谢谢你。 最佳答案 首先，您可以运行一个写入YAML配置文件的独立脚本:require"yaml"File.write("path_to_yaml_file",[arg1,arg2].to_yaml)然后，在您的应用中阅读它:require"yaml"arg

我已经在Sinatra上创建了应用程序，它代表了一个简单的API。我想在生产和开发上进行部署。我想在部署时选择，是开发还是生产，一些方法的逻辑应该改变，这取决于部署类型。是否有任何想法，如何完成以及解决此问题的一些示例。例子:我有代码get'/api/test'doreturn"Itisdev"end但是在部署到生产环境之后我想在运行/api/test之后看到ItisPROD如何实现？ 最佳答案 根据SinatraDocumentation:EnvironmentscanbesetthroughtheRACK_ENVenvironm
我正在尝试使用boilerpipe来自JRuby。我看过guide从JRuby调用Java，并成功地将它与另一个Java包一起使用，但无法弄清楚为什么同样的东西不能用于boilerpipe。我正在尝试基本上从JRuby中执行与此Java等效的操作:URLurl=newURL("http://www.example.com/some-location/index.html");Stringtext=ArticleExtractor.INSTANCE.getText(url);在JRuby中试过这个:require'java'url=java.net.URL.new("http://www

之前在培训新生的时候，windows环境下配置opencv环境一直教的都是网上主流的vsstudio配置属性表，但是这个似乎对新生来说难度略高(虽然个人觉得完全是他们自己的问题)，加之暑假之后对cmake实在是爱不释手，且这样配置确实十分简单(其实都不需要配置)，故斗胆妄言vscode下配置CV之法。其实极为简单，图比较多所以很长。如果你看此文还配不好，你应该思考一下是不是自己的问题。闲话少说，直接开始。0.CMkae简介有的人到大二了都不知道cmake是什么，我不说是谁。CMake是一个开源免费并且跨平台的构建工具，可以用简单的语句来描述所有平台的编译过程。它能够根据当前所在平台输出对应的m
这篇文章是继上一篇文章“Observability：从零开始创建Java微服务并监控它（一）”的续篇。在上一篇文章中，我们讲述了如何创建一个Javaweb应用，并使用Filebeat来收集应用所生成的日志。在今天的文章中，我来详述如何收集应用的指标，使用APM来监控应用并监督web服务的在线情况。源码可以在地址 https://github.com/liu-xiao-guo/java_observability 进行下载。摄入指标指标被视为可以随时更改的时间点值。当前请求的数量可以改变任何毫秒。你可能有1000个请求的峰值，然后一切都回到一个请求。这也意味着这些指标可能不准确，你还想提取最小/
HashMap中为什么引入红黑树，而不是AVL树呢1.概述开始学习这个知识点之前我们需要知道，在JDK1.8以及之前，针对HashMap有什么不同。JDK1.7的时候，HashMap的底层实现是数组+链表JDK1.8的时候，HashMap的底层实现是数组+链表+红黑树我们要思考一个问题，为什么要从链表转为红黑树呢。首先先让我们了解下链表有什么不好？？？2.链表上述的截图其实就是链表的结构，我们来看下链表的增删改查的时间复杂度增：因为链表不是线性结构，所以每次添加的时候，只需要移动一个节点，所以可以理解为复杂度是N(1)删：算法时间复杂度跟增保持一致查：既然是非线性结构，所以查询某一个节点的时候
