org.elasticsearch.common.xcontent.DeprecationHandler 使用 Elasticsearch REST 高级客户端时出现异常
org.elasticsearch.common.xcontent.DeprecationHandler Exception while using Elasticsearch REST High level client
我在尝试使用 Elasticsearch 高休息客户端时遇到以下异常。
我正在使用 Spring Boot 2.0.4 和 Elasticsearch 6.4 版本。用例只是用一些数据创建索引，然后检索相同的数据..

我刚刚按照 dependencies 的 elasticsearch 文档进行了正确设置。
我的 Gradle 依赖项是
dependencies {
compile 'org.elasticsearch.client:elasticsearch-rest-high-level-client:6.4.0'
}
为了简单起见，给出了一个简短的代码版本..
@RestController
public class ElasticController {
@RequestMapping("/posts")
public void getData() {
RestHighLevelClient client = new RestHighLevelClient(
RestClient.builder(
new HttpHost("localhost", "9200","http")));
GetRequest request = new GetRequest("posts", "doc", "1");
GetResponse response = client.get(request, RequestOptions.DEFAULT);
System.out.println(response.getSource().toString());
}
}
有人可以帮忙吗？
是的，我发现以下 link 有助于确定问题..
根据 elasticsearch documentation，只需要添加“elasticsearch-rest-high-level-client”依赖项。但是，我只是观察到它在 Gradle build 中，它选择了另一个版本号较低的依赖项；在我的例子中是 5.6.10
现在，我刚刚在 build.gradle 中添加了以下依赖项。
dependencies {
compile group: 'org.elasticsearch', name: 'elasticsearch', version: '6.4.0'
compile group: 'org.elasticsearch.client', name: 'elasticsearch-rest-high-level-client', version: '6.4.0'
compile('org.springframework.boot:spring-boot-starter-web')
testCompile('org.springframework.boot:spring-boot-starter-test')
}
那就解决了。我在其他论坛上看到了同样的问题，但希望这对他们有帮助..（可能 Elasticsearch 文档也必须包括这个）。
我遇到了同样的问题。最后我发现我必须提供 org.elasticsearch:elasticsearch 依赖项并保持与我的 rest-high-level-client 相同的版本。
如果我不这样做，它将默认为 org.elasticsearch:elasticsearch:5.6.10，但我使用的是 rest-client 6.4.x
我为这个问题苦苦挣扎。基本上，此异常的根本原因是 Elastic-Search Lib、elasticsearch-rest-high-level-client 和 ElasticSearch Server 的版本不匹配。
我正在使用 ElasticSearch Server 7.4 和 Apache Flink 1.10。我在 POM 中为 Flink-Elastic-Search Sink 添加了以下依赖项：
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-connector-elasticsearch7_2.11</artifactId>
<version>1.10.0</version>
</dependency>
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-high-level-client</artifactId>
<version>7.4.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.elasticsearch/elasticsearch -->
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>7.4.0</version>
</dependency>
这对我来说效果很好。
注意：elasticsearch-rest-high-level-client版本的Elastic-Search Server版本和依赖版本，以及Elastic-Search，SINK connector要完全一致才能避免这个问题。
我遇到了同样的问题
在我的senario中，我项目的pom.xml扩展了spring-boot-starter-parent，并且有一个关于elasticsearch定义的maven属性elasticsearch.version和dependencyManagement在 spring-boot-dependencies 中，它是 spring-boot-starter-parent.
的父级
因此，elasticsearch-client所依赖的elasticsearch工件的实际版本可能与您指定给elasticsearch-client的版本不同。然后由于 elasticsearch-client 和它所依赖的 elasticsearch 工件之间的版本不匹配，你得到了一个 ClassNotFoudException。
<elasticsearch.version>5.6.8</elasticsearch.version>
snapshot
<dependencyManagement>
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>${elasticsearch.version}</version>

<dependency>
<groupId>org.elasticsearch.plugin</groupId>
<artifactId>transport-netty4-client</artifactId>

为了解决这个问题，您可以简单地在 pom.xml 中定义 elasticsearch.version 属性 来覆盖 parent pom.xml
中的那个
<elasticsearch.version>The version you want</elasticsearch.version>

我刚刚按照 dependencies 的 elasticsearch 文档进行了正确设置。
我的 Gradle 依赖项是
dependencies {
compile 'org.elasticsearch.client:elasticsearch-rest-high-level-client:6.4.0'
}
为了简单起见，给出了一个简短的代码版本..
@RestController
public class ElasticController {
@RequestMapping("/posts")
public void getData() {
RestHighLevelClient client = new RestHighLevelClient(
RestClient.builder(
new HttpHost("localhost", "9200","http")));
GetRequest request = new GetRequest("posts", "doc", "1");
GetResponse response = client.get(request, RequestOptions.DEFAULT);
System.out.println(response.getSource().toString());
}
}
有人可以帮忙吗？
是的，我发现以下 link 有助于确定问题..
根据 elasticsearch documentation，只需要添加“elasticsearch-rest-high-level-client”依赖项。但是，我只是观察到它在 Gradle build 中，它选择了另一个版本号较低的依赖项；在我的例子中是 5.6.10
现在，我刚刚在 build.gradle 中添加了以下依赖项。
dependencies {
compile group: 'org.elasticsearch', name: 'elasticsearch', version: '6.4.0'
compile group: 'org.elasticsearch.client', name: 'elasticsearch-rest-high-level-client', version: '6.4.0'
compile('org.springframework.boot:spring-boot-starter-web')
testCompile('org.springframework.boot:spring-boot-starter-test')
}
那就解决了。我在其他论坛上看到了同样的问题，但希望这对他们有帮助..（可能 Elasticsearch 文档也必须包括这个）。
我遇到了同样的问题。最后我发现我必须提供 org.elasticsearch:elasticsearch 依赖项并保持与我的 rest-high-level-client 相同的版本。
如果我不这样做，它将默认为 org.elasticsearch:elasticsearch:5.6.10，但我使用的是 rest-client 6.4.x
我为这个问题苦苦挣扎。基本上，此异常的根本原因是 Elastic-Search Lib、elasticsearch-rest-high-level-client 和 ElasticSearch Server 的版本不匹配。 我正在使用 ElasticSearch Server 7.4 和 Apache Flink 1.10。我在 POM 中为 Flink-Elastic-Search Sink 添加了以下依赖项：
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-connector-elasticsearch7_2.11</artifactId>
<version>1.10.0</version>
</dependency>
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-high-level-client</artifactId>
<version>7.4.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.elasticsearch/elasticsearch -->
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>7.4.0</version>
</dependency>
这对我来说效果很好。
注意：elasticsearch-rest-high-level-client版本的Elastic-Search Server版本和依赖版本，以及Elastic-Search，SINK connector要完全一致才能避免这个问题。
我遇到了同样的问题
在我的senario中，我项目的pom.xml扩展了spring-boot-starter-parent，并且有一个关于elasticsearch定义的maven属性elasticsearch.version和dependencyManagement在 spring-boot-dependencies 中，它是 spring-boot-starter-parent.
因此，elasticsearch-client所依赖的elasticsearch工件的实际版本可能与您指定给elasticsearch-client的版本不同。然后由于 elasticsearch-client 和它所依赖的 elasticsearch 工件之间的版本不匹配，你得到了一个 ClassNotFoudException。
<elasticsearch.version>5.6.8</elasticsearch.version>

为了解决这个问题，您可以简单地在 pom.xml 中定义 elasticsearch.version 属性 来覆盖 parent pom.xml
<elasticsearch.version>The version you want</elasticsearch.version>
