1 Ubuntu上部署ElasticSearch

准备一台服务器，IP是192.168.100.200

1.1 安装JDK8

首先需要部署JDK8+，这里我使用了JDK8

sudo apt-get install -y openjdk-8-jdk;

1.2 下载ElasticSearch

mkdir -p /home/user/softwares;
cd /home/user/softwares;
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.16.1-linux-x86_64.tar.gz;

1.3 解压，改文件夹名

tar -zxvf elasticsearch-8.16.1-linux-x86_64.tar.gz;
mv elasticsearch-8.16.1 elasticsearch;

1.4 修改参数，减少内存消耗量

vim /home/user/softwares/elasticsearch/config/jvm.options;

-Xms1g    
-Xmx1g
vim /home/user/softwares/elasticsearch/config/elasticsearch.yml;
node.name: node-1            #配置当前es节点名称（默认是被注释的，并且默认有一个节点名）
cluster.name: my-application #默认是被注释的，并且默认有一个集群名
path.data: /home/user/elasticsearch/data     # 数据目录位置
path.logs: /home/user/elasticsearch/logs     # 日志目录位置
network.host: 0.0.0.0        #绑定的ip：默认只允许本机访问，修改为0.0.0.0后则可以远程访问cluster.initial_master_nodes: ["node-1", "node-2"] #默认是被注释的 设置master节点列表 用逗号分隔
xpack.security.enabled: false
xpack.security.http.ssl:enabled: false
xpack.security.transport.ssl:enabled: false
mkdir -p /home/user/elasticsearch/data;
mkdir -p /home/user/elasticsearch/logs;

1.5 启动

cd /home/user/softwares/elasticsearch/bin;
nohup ./elasticsearch &

1.6 宿主机访问

http://192.168.100.200:9200/
{"name": "node-1","cluster_name": "my-application","cluster_uuid": "GFf-TSlmQkuV_aceGLv--A","version": {"number": "8.16.1","build_flavor": "default","build_type": "tar","build_hash": "ffe992aa682c1968b5df375b5095b3a21f122bf3","build_date": "2024-11-19T16:00:31.793213192Z","build_snapshot": false,"lucene_version": "9.12.0","minimum_wire_compatibility_version": "7.17.0","minimum_index_compatibility_version": "7.0.0"},"tagline": "You Know, for Search"
}

2 Java连接ElasticSearch环境搭建

3 ElasticSearch基本配置

3.2 application.yml的配置

server:port: 8003
spring:application:name: elasticsearch-testprofiles:active: dev
machine-no: 1

3.3 application-dev.yml的配置

test，prod，自行配置

spring:elasticsearch:uris: http://192.168.100.200:9200
logging:file:path: D:/log/SpringBoot3-Testname: ${logging.file.path}/test.log

4 正式测试

4.1 基本插入

}

实体类实现接口

package com.sliverbullet.repository;import com.sliverbullet.bean.EmployeeInfo;
import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;public interface EmployeeInfoRepository extends ElasticsearchRepository<EmployeeInfo, Long> {}

Controller层

    @Value("${machine-no}")private String machineNo;@Resourceprivate EmployeeInfoRepository elasticRepository;@RequestMapping("/save")public String save(@RequestBody EmployeeInfo param) {DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSSSSSSS");LocalDateTime localDateTime = LocalDateTime.now();String formattedDate = dateTimeFormatter.format(localDateTime);log.info("【SpringBoot3测试】-【ElasticSearch测试】：{}", formattedDate);EmployeeInfo employeeInfo = new EmployeeInfo(param.getId(), param.getJobNo(), param.getName(), param.getEnglishName(), param.getJob(), param.getSex(), param.getAge(), param.getSalary(), param.getJobDay(), param.getRemark());EmployeeInfo result = elasticRepository.save(employeeInfo);log.info("【ElasticSearch测试】-【插入结果】：{}", JSONObject.toJSONString(result));return JSONObject.toJSONString(result);}

测试

    /*** 基本插入** @return void*/@Testpublic void save() {String url = "http://127.0.0.1:8003/save";JSONObject request = new JSONObject();request.put("id", 6001L);request.put("job_no", "2001");request.put("name", "张三");request.put("english_name", "zhangsan");request.put("job", "Java");request.put("sex", 1);request.put("age", 21);request.put("salary", new BigDecimal("10000.00"));request.put("job_day", new Date());request.put("remark", request.toJSONString());String resp = HttpUtil.post(url, JSONObject.toJSONString(request));log.info("基本同步消息请求结果：{}", resp);}

4.2 ID查询

Controller层

    @Value("${machine-no}")private String machineNo;@Resourceprivate EmployeeInfoRepository elasticRepository;@RequestMapping("/find")public String find(@RequestBody EmployeeInfo param) {DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSSSSSSS");LocalDateTime localDateTime = LocalDateTime.now();String formattedDate = dateTimeFormatter.format(localDateTime);log.info("【SpringBoot3测试】-【ElasticSearch测试】：{}", formattedDate);Optional<EmployeeInfo>  employeeInfo = elasticRepository.findById(param.getId());log.info("【ElasticSearch测试】-【单条查询结果】：{}", JSONObject.toJSONString(employeeInfo));return JSONObject.toJSONString(employeeInfo);}

测试

    /*** 基本查询** @return void*/@Testpublic void find() {String url = "http://127.0.0.1:8003/find";JSONObject request = new JSONObject();request.put("id", 6001L);String resp = HttpUtil.post(url, JSONObject.toJSONString(request));log.info("基本同步查询请求结果：{}", resp);}
