+# Spring Boot + Elasticsearch 整合Demo
+
+### 框架技术
+* SpringBoot 2.3.7.RELEASE
+* Elasticsearch 7.6.2
+* MariaDB 10.1.37
+
+### 项目配置
+* Elasticsearch 配置
+```properties
+#非必须配置，默认值为localhost
+es.host=localhost
+#非必须配置，默认值9200
+es.port=9200
+```
+* 数据库配置
+在application.properties
+
+
+### 启动项目
+1. 首先启动Elasticsearch服务
+```shell
+ ${es_home}/bin/elasticsearch
+```
+>无需手动创建索引
+
+2. 在数据库中创建表t_book
+```mysql
+create table t_book
+(
+	id int unsigned auto_increment primary key,
+	title varchar(30) default ''  comment '书名',
+	author varchar(20) default ''  comment '作者',
+	price decimal(10,2) comment '价格',
+	create_time datetime comment '创建时间',
+	update_time datetime comment '更新时间'
+);
+```
+3. 插入数据到数据库和ES
+>执行com.gyb.elasticsearch.demo.ESBookOperationTests.testBatchAddBook()方法进行测试数据的插入
+
+4. 启动项目
+```shell
+./mvnw spring-boot:run
+```
