springboot配置文件 SpringBoot整合Elasticsearch+ik分词器+kibana

话不多说直接开整
首先是版本对应，SpringBoot和ES之间的版本必须要按照官方给的对照表进行安装，最新版本对照表如下：

（官网链接：https://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/#preface.requirements）
1、开始安装ES：
我本地的SpringBoot版本是2.3.4，所以我采用的ES版本是7.6.2版本，然后前往官网进行下载，小伙伴们也可以直接下载我所用的版本（链接：https://pan.baidu.com/s/1KoRo5h1nHY82c3B5RxfmrA 提取码：bcov）：
ES官方下载链接：https://www.elastic.co/cn/downloads/past-releases#elasticsearch
将下载下来的文件上传到服务器上，我上传的目录是usr/local/es，然后开始解压：
tar -zxvf elasticsearch-7.6.2-linux-x86_64.tar.gz解压后修改config目录下的elasticsearch.yml文件，贴一下我修改的内容：
1 # ======================== Elasticsearch Configuration ========================= 2 # 3 # NOTE: Elasticsearch comes with reasonable defaults for most settings. 4 #Before you set out to tweak and tune the configuration, make sure you 5 #understand what are you trying to accomplish and the consequences. 6 # 7 # The primary way of configuring a node is via this file. This template lists 8 # the most important settings you may want to configure for a production cluster. 9 #10 # Please consult the documentation for further information on configuration options:11 # https://www.elastic.co/guide/en/elasticsearch/reference/index.html12 #13 # ---------------------------------- Cluster -----------------------------------14 #15 # Use a descriptive name for your cluster:16 # 这个是名字17 cluster.name: my-application18 #19 # ------------------------------------ Node ------------------------------------20 #21 # Use a descriptive name for the node:22 # 这个是节点名称23 node.name: es-node-024 #25 # Add custom attributes to the node:26 #27 #node.attr.rack: r128 #29 # ----------------------------------- Paths ------------------------------------30 #31 # Path to directory where to store the data (separate multiple locations by comma):32 # 这个是数据存放的路径33 path.data: /usr/local/elasticsearch-7.6.2/data34 #35 # Path to log files:36 # 这个是log存放的路径37 path.logs: /usr/local/elasticsearch-7.6.2/logs38 #39 # ----------------------------------- Memory -----------------------------------40 #41 # Lock the memory on startup:42 #43 #bootstrap.memory_lock: true44 #45 # Make sure that the heap size is set to about half the memory available46 # on the system and that the owner of the process is allowed to use this47 # limit.48 #49 50 51 # Elasticsearch performs poorly when the system is swapping the memory.52 #53 # ---------------------------------- Network -----------------------------------54 #55 # Set the bind address to a specific IP (IPv4 or IPv6):56 # 注：如果是云服务器的话需要填写内外地址，我这里是内网。57 network.host: 192.168.0.458 http.host: 0.0.0.059 #60 # Set a custom port for HTTP:61 # 启动端口号62 http.port: 920063 #64 # For more information, consult the network module documentation.65 #66 # --------------------------------- Discovery ----------------------------------67 #68 # Pass an initial list of hosts to perform discovery when this node is started:69 # The default list of hosts is ["127.0.0.1", "[::1]"]70 #71 #discovery.seed_hosts: ["host1", "host2"]72 #73 # Bootstrap the cluster using an initial set of master-eligible nodes:74 # 初始化节点，可以有多个75 cluster.initial_master_nodes: ["es-node-0"]76 #77 # For more information, consult the discovery and cluster formation module documentation.78 #79 # ---------------------------------- Gateway -----------------------------------80 #81 # Block initial recovery after a full cluster restart until N nodes are started:82 #83 #gateway.recover_after_nodes: 384 #85 # For more information, consult the gateway module documentation.86 #87 # ---------------------------------- Various -----------------------------------88 #89 # Require explicit names when deleting indices:90 #91 #action.destructive_requires_name: true

因为安全问题elasticsearch 不让用root用户直接运行，所以要创建新用户：
useradd espasswd es然后输入密码，最小8位数，为用户赋权限：
chown -R es:es /usr/local/es/切换成es用户，cd 到bin目录下启动，第一种是前台启动，第二种是后台启动：
./elasticsearch./elasticsearch -d

文章插图
如果启动提示了这个错误需要在/etc/sysctl.conf文件最后添加一行
vm.max_map_count=262144执行/sbin/sysctl -p 立即生效，之后再重新启动就好了，如果启动的时候提示“failed to authenticate user [elastic]”，不要慌，继续执行下面的步骤；

文章插图
在上面ES的yml配置中，我们配置了账号验证，所以我们需要重置一下ES账号的密码（确保es已经成功启动才能重置；在es的bin目录下执行）：
./elasticsearch-setup-passwords interactive

文章插图
建议设置成相同的密码，方便记忆，设置成功后就可以直接打开网页去访问了，访问地址是ip:9200，然后输入账号：“elastic”，密码：“123456”

文章插图
能看到这些就代表ES已经成功启动了！！！
（注：如果小伙伴们是云服务器的话要注意开放服务器的安全组，不然访问不到，开放9200和9300端口，下面的Kibana也需要开放5601的端口！！！）
然后我们现在配置一下ik分词器（中文分词）：
ik分词器也是同理，版本必须一致！！！然后把文件上传到ES的plugins目录下，创建ik目录，解压到ik目录下即可。

文章插图
启动的时候出现这个就代表配置成功了。

2、接下来我们开始配置Kibana：
Kibana的版本也需要和ES对应才行（官方地址：https://www.elastic.co/cn/support/matrix#matrix_compatibility）：

文章插图
下载好的Kibana上传后进行解压缩（官方下载地址：https://www.elastic.co/cn/downloads/kibana#ga-release）：
tar -zxvf kibana-7.6.2-linux-x86_64.tar.gz修改config目录下的kibana.yml文件：
# Kibana is served by a back end server. This setting specifies the port to use.server.port: 5601# Specifies the address to which the Kibana server will bind. IP addresses and host names are both valid values.# The default is 'localhost', which usually means remote machines will not be able to connect.# To allow connections from remote users, set this parameter to a non-loopback address.#server.host: "localhost"
# 代表都能访问server.host: "0.0.0.0"# Enables you to specify a path to mount Kibana at if you are running behind a proxy.# Use the `server.rewriteBasePath` setting to tell Kibana if it should remove the basePath# from requests it receives, and to prevent a deprecation warning at startup.# This setting cannot end in a slash.#server.basePath: ""# Specifies whether Kibana should rewrite requests that are prefixed with# `server.basePath` or require that they are rewritten by your reverse proxy.# This setting was effectively always `false` before Kibana 6.3 and will# default to `true` starting in Kibana 7.0.#server.rewriteBasePath: false# The maximum payload size in bytes for incoming server requests.#server.maxPayloadBytes: 1048576# The Kibana server's name.This is used for display purposes.#server.name: "your-hostname"# The URLs of the Elasticsearch instances to use for all your queries.
# 配置ES的地址elasticsearch.hosts: ["http://192.168.0.4:9200"]# When this setting's value is true Kibana uses the hostname specified in the server.host# setting. When the value of this setting is false, Kibana uses the hostname of the host# that connects to this Kibana instance.#elasticsearch.preserveHost: true# Kibana uses an index in Elasticsearch to store saved searches, visualizations and# dashboards. Kibana creates a new index if the index doesn't already exist.#kibana.index: ".kibana"# The default application to load.#kibana.defaultAppId: "home"# If your Elasticsearch is protected with basic authentication, these settings provide# the username and password that the Kibana server uses to perform maintenance on the Kibana# index at startup. Your Kibana users still need to authenticate with Elasticsearch, which# is proxied through the Kibana server.
# ES的账号密码elasticsearch.username: "elastic"elasticsearch.password: "123456"# Enables SSL and paths to the PEM-format SSL certificate and SSL key files, respectively.# These settings enable SSL for outgoing requests from the Kibana server to the browser.#server.ssl.enabled: false#server.ssl.certificate: /path/to/your/server.crt#server.ssl.key: /path/to/your/server.key# Optional settings that provide the paths to the PEM-format SSL certificate and key files.# These files are used to verify the identity of Kibana to Elasticsearch and are required when# xpack.security.http.ssl.client_authentication in Elasticsearch is set to required.#elasticsearch.ssl.certificate: /path/to/your/client.crt#elasticsearch.ssl.key: /path/to/your/client.key# Optional setting that enables you to specify a path to the PEM file for the certificate# authority for your Elasticsearch instance.#elasticsearch.ssl.certificateAuthorities: [ "/path/to/your/CA.pem" ]# To disregard the validity of SSL certificates, change this setting's value to 'none'.#elasticsearch.ssl.verificationMode: full# Time in milliseconds to wait for Elasticsearch to respond to pings. Defaults to the value of# the elasticsearch.requestTimeout setting.#elasticsearch.pingTimeout: 1500# Time in milliseconds to wait for responses from the back end or Elasticsearch. This value# must be a positive integer.#elasticsearch.requestTimeout: 30000# List of Kibana client-side headers to send to Elasticsearch. To send *no* client-side# headers, set this value to [] (an empty list).#elasticsearch.requestHeadersWhitelist: [ authorization ]# Header names and values that are sent to Elasticsearch. Any custom headers cannot be overwritten# by client-side headers, regardless of the elasticsearch.requestHeadersWhitelist configuration.#elasticsearch.customHeaders: {}# Time in milliseconds for Elasticsearch to wait for responses from shards. Set to 0 to disable.#elasticsearch.shardTimeout: 30000# Time in milliseconds to wait for Elasticsearch at Kibana startup before retrying.#elasticsearch.startupTimeout: 5000# Logs queries sent to Elasticsearch. Requires logging.verbose set to true.#elasticsearch.logQueries: false# Specifies the path where Kibana creates the process ID file.#pid.file: /var/run/kibana.pid# Enables you specify a file where Kibana stores log output.#logging.dest: stdout# Set the value of this setting to true to suppress all logging output.#logging.silent: false# Set the value of this setting to true to suppress all logging output other than error messages.#logging.quiet: false# Set the value of this setting to true to log all events, including system usage information# and all requests.#logging.verbose: false# Set the interval in milliseconds to sample system and process performance# metrics. Minimum is 100ms. Defaults to 5000.#ops.interval: 5000# Specifies locale to be used for all localizable strings, dates and number formats.# Supported languages are the following: English - en , by default , Chinese - zh-CN .
# 配置中文i18n.locale: "zh-CN"配置完成后启动ES，再输入命令启动kibana（在bin目录下输入该命令）：
nohup ./kibana &如果不想后台启动的直接输入：
./kibana

没有出现error就可以直接ip:5601去访问了，然后输入之前ES设置的账号：elastic 密码：123456，然后大功告成！！！

kibana的操作后面集成了spring boot后再做简单的介绍。
3、最后开始集成到我们的spring boot项目中去，我本地的spring boot版本是2.3.4版本

文章插图
下面是需要引用的jar包，在pom文件中添加以下依赖：
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-elasticsearch</artifactId></dependency>一般情况下spring boot会自动对应相应的ES版本，下载好jar包后可以看项目下的jar包的版本，确认一下，版本是否正确，我这边是7.6.2的版本。

文章插图
如果版本不正确的话可以手动修改一下版本，在pom.xml文件中的<properties>添加如下代码：
<properties>
<elasticsearch.version>7.6.2</elasticsearch.version>
</properties>配置ES连接bean：
package com.zsi.geek_insight.config;import com.zsi.geek_insight.util.EsUtils;import org.apache.http.HttpHost;import org.apache.http.auth.AuthScope;import org.apache.http.auth.UsernamePasswordCredentials;import org.apache.http.client.CredentialsProvider;import org.apache.http.impl.client.BasicCredentialsProvider;import org.elasticsearch.client.RestClient;import org.elasticsearch.client.RestClientBuilder;import org.elasticsearch.client.RestHighLevelClient;import org.springframework.beans.factory.annotation.Value;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;@Configurationpublic class ElasticsearchConfiguration {@Value("${elasticsearch.host}")private String host;@Value("${elasticsearch.port}")private int port;@Value("${elasticsearch.username}")private String USERNAME;@Value("${elasticsearch.password}")private String PASSWORD;@Bean(destroyMethod = "close", name = "client")public RestHighLevelClient restHighLevelClient() {//如果没配置密码就可以不用下面这两部final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(USERNAME, PASSWORD));RestClientBuilder builder = RestClient.builder(new HttpHost(host, port, "http")).setHttpClientConfigCallback(httpClientBuilder -> {httpClientBuilder.disableAuthCaching();return httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider);});RestHighLevelClient restHighLevelClient = new RestHighLevelClient(builder);
//这里我写了一个静态的工具类，所以笨笨的写了一个ES的初始化，
//有大佬可以麻烦帮忙指点一下看有什么更好的方案让静态的工具类能拿到注入到spring中的beannew EsUtils().init(restHighLevelClient);return restHighLevelClient;}}在application.properties中配置ES的账号密码：
# es的链接地址
elasticsearch.host = 192.168.0.4
# 端口号
elasticsearch.port = 9200# 账号、密码elasticsearch.username = elasticelasticsearch.password = 123456ES操作工具类：

点击左上角的默认图片，点击管理空间，然后点索引管理就能看到所创建好的索引了：

这个就是我们刚刚创建好的索引：

文章插图
创建好索引后我们添加数据，调用/financialRegulationsData/addAll：

文章插图
可以发现成功添加了两条，然后我们现在可以看一下数据是否都添加进去了，点击索引模式，点击创建索引模式，根据索引名称创建一个查询界面：
　

文章插图
创建成功后点击左菜单栏的指南针图标Discover进去页面查看：

文章插图
在这里我们就能看到2条数据已经成功插入到了ES中，最后我们做查询，输入“银保监会保护局”，查询出来的数据也做了高亮的处理：

文章插图
　至此SpringBoot集成ES就暂时搞定了，最后提一点，ES的查询默认不会超过1W条数据，如果需要超过1W条需要在kibana中输入命令设置一下：
设置ES中最大的返回行数PUT 索引名称/_settings{"max_result_window":200000}

代码中也需要加一句：
searchQuery.setTrackTotalHits(true);

文章插图
　设置成功后就可以查询超过1w条数据了，其中的数字大家酌情设置。
最后再和大家说一个小秘密，如果数据量较多的话，搜出来的内容越到后面越不准确，这个时候就需要增加一个设置了，需要在这句代码后面加上一下内容，建议填写百分比，这样会稍微准确一点，如果填写数字的话个人感觉效果不太好。
QueryBuilders.matchQuery("regulationsName", name).minimumShouldMatch("70%")到这里以上就是所有内容了，如有问题欢迎指正！
修改、删除由于篇幅问题如果大家有需要的话我再更新一波。
