Springdata集成ElasticSearch—增删改查

该示例以product 为JavaBean对象，使用springdata集成ES，用productDao对ES进行方便的增删改查

环境配置

maven

properties

application.properties

# elasticsearch 主机和端口
elasticsearch.host=127.0.0.1
elasticsearch.port=9200
logging.level.com.atguigu.es=debug

RunApp

代码配置

bean.Product

前四个注解是lombok注解，用于更方便创建JavaBean

config.EsConfig

dao.productDao

使用

测试类注意事项

不知道为什么，测试类一定要放在java包里，并且添加@RunWith(SpringRunner.class)注解才有效

示例如下：

创建索引

第一次运行程序会自动创建索引

增删改查

@Autowird 注入ProductDao

创建

修改

根据id查询

查询所有

删除

批量新增

分页查询

文档搜索-条件查询

文档搜索-条件查询+分页
