= Java API (deprecated)

|
|
== Preface
|
|
|
|
deprecated[7.0.0, The `TransportClient` is deprecated in favour of the {java-rest}/java-rest-high.html[Java High Level REST Client] and will be removed in Elasticsearch 8.0. The {java-rest}/java-rest-high-level-migration.html[migration guide] describes all the steps needed to migrate.]
|
|
|
|
This section describes the Java API that Elasticsearch provides. All
|
|
Elasticsearch operations are executed using a
|
|
<<client,Client>> object. All
|
|
operations are completely asynchronous in nature (either accepts a
|
|
listener, or returns a future).
|
|
|
|
Additionally, operations on a client may be accumulated and executed in
|
|
<<java-docs-bulk,Bulk>>.
|
|
|
|
Note, all the APIs are exposed through the
|
|
Java API (actually, the Java API is used internally to execute them).
|
|
|
|
== Javadoc
|
|
|
|
The javadoc for the transport client can be found at {transport-client-javadoc}/index.html.
|
|
|
|
== Maven Repository
|
|
|
|
Elasticsearch is hosted on
|
|
http://search.maven.org/#search%7Cga%7C1%7Cg%3A%22org.elasticsearch.client%22[Maven
|
|
Central].
|
|
|
|
For example, you can define the latest version in your `pom.xml` file:
|
|
|
|
["source","xml",subs="attributes"]
|
|
--------------------------------------------------
|
|
<dependency>
|
|
<groupId>org.elasticsearch.client</groupId>
|
|
<artifactId>transport</artifactId>
|
|
<version>{version}</version>
|
|
</dependency>
|

|
=== Lucene Snapshot repository
|
|
|
|
The very first releases of any major version (like a beta), might have been built on top of a Lucene Snapshot version.
|
|
In such a case you will be unable to resolve the Lucene dependencies of the client.
|
|
|
|
For example, if you want to use the `6.0.0-beta1` version which depends on Lucene `7.0.0-snapshot-00142c9`, you must
|
|
define the following repository.
|
|
|
|
For Maven:
|
|
|
|
["source","xml",subs="attributes"]
|
|
--------------------------------------------------
|
|
<repository>
|
|
<id>elastic-lucene-snapshots</id>
|
|
<name>Elastic Lucene Snapshots</name>
|
|
<url>https://s3.amazonaws.com/download.elasticsearch.org/lucenesnapshots/00142c9</url>
|
|
<releases><enabled>true</enabled></releases>
|
|
<snapshots><enabled>false</enabled></snapshots>
|
|
</repository>
|
|
--------------------------------------------------
|
|
|
|
For Gradle:
|
|
|
|
["source","groovy",subs="attributes"]
|
|
--------------------------------------------------
|
|
maven {
|
|
name "lucene-snapshots"
|
|
url 'https://s3.amazonaws.com/download.elasticsearch.org/lucenesnapshots/00142c9'
|
|
}
|
|
--------------------------------------------------
|
|
|
|
=== Log4j 2 Logger
|
|
|
|
You need to also include Log4j 2 dependencies:
|
|
|
|
["source","xml",subs="attributes"]
|
|
--------------------------------------------------
|
|
<dependency>
|
|
<groupId>org.apache.logging.log4j</groupId>
|
|
<artifactId>log4j-core</artifactId>
|
|
<version>2.11.1</version>
|
|
</dependency>
|
|
--------------------------------------------------
|
|
|
|
And also provide a Log4j 2 configuration file in your classpath.
|
|
For example, you can add in your `src/main/resources` project dir a `log4j2.properties` file like:
|
|
|
|
|
|
["source","properties",subs="attributes"]
|
|
--------------------------------------------------
|
|
appender.console.type = Console
|
|
appender.console.name = console
|
|
appender.console.layout.type = PatternLayout
|
|
appender.console.layout.pattern = [%d{ISO8601}][%-5p][%-25c] %marker%m%n
|
|
|
|
rootLogger.level = info
|
|
rootLogger.appenderRef.console.ref = console
|
|
--------------------------------------------------
|
|
|
|
=== Using another Logger
|
|
|
|
If you want to use another logger than Log4j 2, you can use http://www.slf4j.org/[SLF4J] bridge to do that:
|
|
|
|
["source","xml",subs="attributes"]
|
|
--------------------------------------------------
|
|
<dependency>
|
|
<groupId>org.apache.logging.log4j</groupId>
|
|
<artifactId>log4j-to-slf4j</artifactId>
|
|
<version>2.11.1</version>
|
|
</dependency>
|
|
<dependency>
|
|
<groupId>org.slf4j</groupId>
|
|
<artifactId>slf4j-api</artifactId>
|
|
<version>1.7.24</version>
|
|
</dependency>
|
|
--------------------------------------------------
|
|
|
|
http://www.slf4j.org/manual.html[This page] lists implementations you can use. Pick your favorite logger
|
|
and add it as a dependency. As an example, we will use the `slf4j-simple` logger:
|
|
|
|
["source","xml",subs="attributes"]
|
|
--------------------------------------------------
|
|
<dependency>
|
|
<groupId>org.slf4j</groupId>
|
|
<artifactId>slf4j-simple</artifactId>
|
|
<version>1.7.21</version>
|
|
</dependency>
|
|
