问题描述

在使用 Springboot 整合 ES 的时候，使用 Springboot 时，使用的是 Springboot data 提供的工具，具体依赖如下：

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-elasticsearch</artifactId> </dependency>

注意，

我没有添加 ES 相关的其他依赖；ES 的版本为 6.5.4 测试代码

在新建的 Springboot 项目中，添加上面的那个依赖后，配置 yml 文件如下：

spring: elasticsearch: rest: uris: "服务器地址" read-timeout: "10s"

在 SpringbootTest 中添加测试内容如下：

package cn.smileyan.demo; import java.io.IOException; import org.elasticsearch.action.admin.indices.create.CreateIndexRequest; import org.elasticsearch.action.admin.indices.create.CreateIndexResponse; import org.elasticsearch.action.admin.indices.delete.DeleteIndexRequest; import org.elasticsearch.client.RequestOptions; import org.elasticsearch.client.RestHighLevelClient; import org.junit.jupiter.api.Test; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; /** * @author smileyan */ @SpringBootTest class ElasticsearchDemoApplicationTests { @Autowired private RestHighLevelClient client; @Test public void testCreate() throws IOException { CreateIndexRequest request = new CreateIndexRequest("myindex2"); CreateIndexResponse createIndexResponse = client.indices().create(request, RequestOptions.DEFAULT); assert createIndexResponse.isAcknowledged(); } @Test public void testDelete() throws IOException { DeleteIndexRequest request = new DeleteIndexRequest("myindex2"); client.indices().delete(request, RequestOptions.DEFAULT); } }

注意，运行 testCreate 那种方法测试没有报错，但是 testDelete 报错了。

在启动 Springboot 的时候请注意观察输入的日志： 前面提到过，我使用的版本是 6.5.4，版本冲突。

解决方法非常简单：降低 Springboot 的版本，我的版本是 2.2.13.RELEASE，接着再继续测试，就解决了所有问题。

创建索引 myindex2 ，以及删除这个索引，都可以正常。

总结

版本问题害死人哪。
