es 分词器（五）之elasticsearch-analysis-jieba 8.7.0

今天咱们就来讲一下es jieba 8.7.0 分词器的实现，以及8.x其它版本的实现方式，如果想直接使用es 结巴8.x版本，请直接修改pom文件的elasticsearch.version版本号即可，然后打包安装就行，不需要做太多的操作。

一、elasticsearch-jieba-plugin

最近更新的版本为8.4.1，最近更新的时间停留在2022年，从这之后便无人维护此开源项目

GitHub地址：https://github.com/sing1ee/elasticsearch-jieba-plugin/tree/8.4.1

二、elasticsearch-analysis-jieba

最近更新的版本为6.8.17，比上面的插件更惨，已经有三年无人维护了。

三、决定换壳elasticsearch-jieba-plugin

当前我开发的项目采用的版本为8.7.0，目前在网上无法找到与之匹配的版本。

ik分词器用户比jieba分词器用户多，因为会对应的es版本不断更新，目前ik分词器的版本已经更新至8.12.2，2024年5月14日位置es的最新版本为8.14.x

2024年5月14日es最新版本为8.14.x

四、编译elasticsearch-analysis-jieba分词器

由于原有的插件【elasticsearch-analysis-jieba】已经很久没有人使用，但我又感觉【elasticsearch-analysis-jieba】这个名称比【elasticsearch-jieba-plugin】【https://github.com/sing1ee/elasticsearch-jieba-plugin/tree/8.4.1】这个好听一点，所以我本地新开了一个【elasticsearch-analysis-jieba】项目，将这个【elasticsearch-jieba-plugin】这个项目的代码复制到新建的项目中，因为这个【elasticsearch-jieba-plugin】使用的是gradle管理，我想使用的是maven仓库，所以修改了一下。

4.2 修改plugin-descriptor.properties文件

# Elasticsearch plugin descriptor file
# This file must exist as 'plugin-descriptor.properties' at
# the root directory of all plugins.
#
# A plugin can be 'site', 'jvm', or both.
#
### example site plugin for "foo":
#
# foo.zip <-- zip file for the plugin, with this structure:
#   _site/ <-- the contents that will be served
#   plugin-descriptor.properties <-- example contents below:
#
# site=true
# description=My cool plugin
# version=1.0
#
### example jvm plugin for "foo"
#
# foo.zip <-- zip file for the plugin, with this structure:
#   <arbitrary name1>.jar <-- classes, resources, dependencies
#   <arbitrary nameN>.jar <-- any number of jars
#   plugin-descriptor.properties <-- example contents below:
#
# jvm=true
# classname=foo.bar.BazPlugin
# description=My cool plugin
# version=2.0.0-rc1
# elasticsearch.version=2.0
# java.version=1.7
#
### mandatory elements for all plugins:
#
# 'description': simple summary of the plugin
description=${project.description}
#
# 'version': plugin's version
version=${project.version}
#
# 'name': the plugin name
name=${elasticsearch.plugin.name}
#
# 'classname': the name of the class to load, fully-qualified.
classname=${elasticsearch.plugin.classname}
#
# 'java.version' version of java the code is built against
# use the system property java.specification.version
# version string must be a sequence of nonnegative decimal integers
# separated by "."'s and may have leading zeros
java.version=${maven.compiler.target}
#
# 'elasticsearch.version' version of elasticsearch compiled against
# You will have to release a new version of the plugin for each new
# elasticsearch release. This version is checked when the plugin
# is loaded so Elasticsearch will refuse to start in the presence of
# plugins with the incorrect elasticsearch.version.
elasticsearch.version=${elasticsearch.version}

4.3 新增plugin-security.policy文件

grant {
  // needed because of the hot reload functionality
  permission java.net.SocketPermission "*", "connect,resolve";
  permission java.lang.RuntimePermission "setContextClassLoader";
};

4.4 构建插件

打包

image-20240515221635642

找到打包之后的zip包

image-20240515221711379

放到elasticsearch-8.7.0/plugin/analysis-jieba目录下。

image-20240515221917297

现在，再手动重启一下es就将elasticsearch-analysis-jieba分词器安装好啦。

五、测试jieba分词器

在kibana中创建索引

PUT jieba_index
{
  "settings": {
    "analysis": {
      "analyzer": {
        "my_ana": {
          "tokenizer": "jieba_index",
          "filter": [
            "lowercase"
          ]
        }
      }
    }
  }
}

文本分词器

PUT jieba_index/_analyze
{
  "analyzer" : "my_ana",
  "text" : "黄河之水天上来"
}

返回结果

{
    "tokens": [
        {
            "token": "黄河",
            "start_offset": 0,
            "end_offset": 2,
            "type": "word",
            "position": 0
        },
        {
            "token": "黄河之水天上来",
            "start_offset": 0,
            "end_offset": 7,
            "type": "word",
            "position": 0
        },
        {
            "token": "之水",
            "start_offset": 2,
            "end_offset": 4,
            "type": "word",
            "position": 1
        },
        {
            "token": "天上",
            "start_offset": 4,
            "end_offset": 6,
            "type": "word",
