For the latest stable version, please use Spring Data Elasticsearch 5.4.0! |
Upgrading from 4.4.x to 5.0.x
This section describes breaking changes from version 4.4.x to 5.0.x and how removed features can be replaced by new introduced features.
Deprecations
Custom trace level logging
Logging by setting the property logging.level.org.springframework.data.elasticsearch.client.WIRE=trace
is deprecated now, the Elasticsearch RestClient
provides a better solution that can be activated by setting the logging level of the tracer
package to "trace".
org.springframework.data.elasticsearch.client.erhlc
package
See Package changes, all classes in this package have been deprecated, as the default client implementations to use are the ones based on the new Java Client from Elasticsearch, see New Elasticsearch client
Removal of deprecated code
DateFormat.none
and DateFormat.custom
had been deprecated since version 4.2 and have been removed.
The properties of @Document
that were deprecated since 4.2 have been removed.
Use the @Settings
annotation for these.
@DynamicMapping
and @DynamicMappingValue
have been removed.
Use @Document.dynamic
or @Field.dynamic
instead.
Breaking Changes
Package changes
All the classes that are using or depend on the deprecated Elasticsearch RestHighLevelClient
have been moved to the package org.springframework.data.elasticsearch.client.erhlc
.
By this change we now have a clear separation of code using the old deprecated Elasticsearch libraries, code using the new Elasticsearch client and code that is independent of the client implementation.
Also the reactive implementation that was provided up to now has been moved here, as this implementation contains code that was copied and adapted from Elasticsearch libraries.
If you are using ElasticsearchRestTemplate
directly and not the ElasticsearchOperations
interface you’ll need to adjust your imports as well.
When working with the NativeSearchQuery
class, you’ll need to switch to the NativeQuery
class, which can take a
Query
instance coming from the new Elasticsearch client libraries.
You’ll find plenty of examples in the test code.
Conversion to Java 17 records
The following classes have been converted to Record
, you might need to adjust the use of getter methods from
getProp()
to prop()
:
-
org.springframework.data.elasticsearch.core.AbstractReactiveElasticsearchTemplate.IndexResponseMetaData
-
org.springframework.data.elasticsearch.core.ActiveShardCount
-
org.springframework.data.elasticsearch.support.Version
-
org.springframework.data.elasticsearch.support.ScoreDoc
-
org.springframework.data.elasticsearch.core.query.ScriptData
-
org.springframework.data.elasticsearch.core.query.SeqNoPrimaryTerm
New HttpHeaders class
Until version 4.4 the client configuration used the HttpHeaders
class from the org.springframework:spring-web
project.
This introduces a dependency on that artifact.
Users that do not use spring-web then face an error as this class cannot be found.
In version 5.0 we introduce our own HttpHeaders
to configure the clients.
So if you are using headers in the client configuration, you need to replace org.springframework.http.HttpHeaders
with org.springframework.data.elasticsearch.support.HttpHeaders
.
Hint: You can pass a org.springframework.http
.HttpHeaders
to the addAll()
method of org.springframework.data.elasticsearch.support.HttpHeaders
.
New Elasticsearch client
Spring Data Elasticsearch now uses the new ElasticsearchClient
and has deprecated the use of the previous RestHighLevelClient
.
Imperative style configuration
To configure Spring Data Elasticsearch to use the new client, it is necessary to create a configuration bean that derives from org.springframework.data.elasticsearch.client.elc.ElasticsearchConfiguration
:
@Configuration
public class NewRestClientConfig extends ElasticsearchConfiguration {
@Override
public ClientConfiguration clientConfiguration() {
return ClientConfiguration.builder() //
.connectedTo("localhost:9200") //
.build();
}
}
The configuration is done in the same way as with the old client, but it is not necessary anymore to create more than the configuration bean. With this configuration, the following beans will be available in the Spring application context:
-
a
RestClient
bean, that is the configured low levelRestClient
that is used by the Elasticsearch client -
an
ElasticsearchClient
bean, this is the new client that uses theRestClient
-
an
ElasticsearchOperations
bean, available with the bean names elasticsearchOperations and elasticsearchTemplate, this uses theElasticsearchClient
Reactive style configuration
To use the new client in a reactive environment the only difference is the class from which to derive the configuration:
@Configuration
public class NewRestClientConfig extends ReactiveElasticsearchConfiguration {
@Override
public ClientConfiguration clientConfiguration() {
return ClientConfiguration.builder() //
.connectedTo("localhost:9200") //
.build();
}
}
With this configuration, the following beans will be available in the Spring application context:
-
a
RestClient
bean, that is the configured low levelRestClient
that is used by the Elasticsearch client -
an
ReactiveElasticsearchClient
bean, this is the new reactive client that uses theRestClient
-
an
ReactiveElasticsearchOperations
bean, available with the bean names reactiveElasticsearchOperations and reactiveElasticsearchTemplate, this uses theReactiveElasticsearchClient
Still want to use the old client?
The old deprecated RestHighLevelClient
can still be used, but you will need to add the dependency explicitly to your application as Spring Data Elasticsearch does not pull it in automatically anymore:
<!-- include the RHLC, specify version explicitly -->
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-high-level-client</artifactId>
<version>7.17.5</version>
<exclusions>
<exclusion>
<groupId>commons-logging</groupId>
<artifactId>commons-logging</artifactId>
</exclusion>
</exclusions>
</dependency>
Make sure to specify the version 7.17.6 explicitly, otherwise maven will resolve to 8.5.0, and this does not exist.
