SpringBoot整合ElasticSearch（五）

spring

spring-data-elasticsearch 与安装的elasticsearch 版本不合适会引起很多问题。

编写案例的时候也很遇到了。

下面整理下：

https://docs.spring.io/spring-data/elasticsearch/docs/3.0.6.RELEASE/reference/html/

https://github.com/spring-projects/spring-data-elasticsearch

官方给出的对应版本信息如下：

spring data elasticsearch	elasticsearch
3.2.x	6.5.0
3.1.x	6.2.2
3.0.x	5.5.0
2.1.x	2.4.0
2.0.x	2.2.0
1.3.x	1.5.2

1.安装与spring-data-elasticsearch版本匹配的elasticsearch：

1. 确定自己 spring-data-elasticsearch 依赖的elasticsearch版本

   External liberies中找到自己依赖的elasticsearch版本

   • Maven: org.apache.tomcat:tomcat-annotations-api:8.5.29

   • Maven: org.assertj:assertj-core:2.6.0

   • Maven: org.elasticsearch:elasticsearch:2.4.6

   • Maven: org.elasticsearch:securesm:1.0

   • Maven: org.hamcrest:hamcrest-core:1.3

   • Maven: org.hamcrest:hamcrest-library:1.3

   • Maven: org.hdrhistogram:HdrHistogram:2.1.6

     看到自己使用的2.4.6版本的elasticsearch

2. 安装对应版本的镜像:docker pull registry.docker-cn.com/library/elasticsearch:2.4.6

   下载镜像

    ❯ docker pull registry.docker-cn.com/library/elasticsearch:2.4.6

   查看镜像id

   ❯ docker  images
   REPOSITORY                                     TAG                 IMAGE ID            CREATED             SIZE

   查看已占用端口

    ❯ docker ps
   CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS                                            NAMES

   4a89939026d2        519c56205eb0        "/docker-entrypoint.…"   2 hours ago          Up About an hour    0.0.0.0:9200->9200/tcp, 0.0.0.0:9300->9300/tcp   ES01
   

   安装镜像 将本地9201端口映射到 docker 9200; 将本地9301端口映射到 docker 9300

   ❯ docker  run  -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9201:9200 -p 9301:9300 --name ES02  5e9d896dc62c
   bb8353eecba58935e20f7bcf9c8111bc6e2a4af85f02604179ad1ff4a0adbc67
   

   检查安装情况

   访问：http://localhost:9201/

   {
     "name" : "Odin",
     "cluster_name" : "elasticsearch",
     "cluster_uuid" : "QrpLxdn8Swmy637ffUfKIg",
     "version" : {
       "number" : "2.4.6",
       "build_hash" : "5376dca9f70f3abef96a77f4bb22720ace8240fd",
       "build_timestamp" : "2017-07-18T12:17:44Z",
       "build_snapshot" : false,
       "lucene_version" : "5.5.4"
     },
     "tagline" : "You Know, for Search"
   }
   

   "number" : "2.4.6",安装成功！版本已经更换为2.4.6版。

3. 修改项目中的配置信息

   将使用http协议的jest 端口修改为：9201

   spring.elasticsearch.jest.uris=http://localhost:9201
   

   将spring.data.elasticsearch模块的nodes端口修改为:9301

   spring.data.elasticsearch.cluster-name=elasticsearch
   spring.data.elasticsearch.cluster-nodes=localhost:9301
   

   重启项目,控制台打印：

   adding transport node : localhost:9301

   Started Springboot02ElasticApplication in 4.68 seconds (JVM running for 5.678)

   无异常，启动成功！
