Spring Data ArangoDB

This integration is a library for accessing data stored in ArangoDB in Spring-based Java application. Spring Data provides a consistent interface for accessing various types of data sources. Spring Data ArangoDB implements this for ArangoDB and provides mapping of Java objects to ArangoDB documents (ODM).

Supported versions

Spring Data ArangoDB is compatible with:

  • all the still supported Spring Boot 3.x versions  and related Spring Framework versions
  • all the still supported ArangoDB versions 
  • all the still supported Spring Boot 2.x versions  and related Spring Framework versions
  • all the still supported ArangoDB versions 

Maven

To use Spring Data ArangoDB in your project, your build automation tool needs to be configured to include and use the Spring Data ArangoDB dependency. Example with Maven (substitute x.x.x with the latest Spring Data ArangoDB version):

<dependency>
  <groupId>com.arangodb</groupId>
  <artifactId>arangodb-spring-data</artifactId>
  <version>x.x.x</version>
</dependency>

There is a demonstration app , which contains common use cases and examples of how to use Spring Data ArangoDB’s functionality.

Configuration

You can use Java to configure your Spring Data environment as show below. Setting up the underlying driver (ArangoDB.Builder) with default configuration automatically loads a properties file arangodb.properties, if it exists in the classpath.

@Configuration
@EnableArangoRepositories(basePackages = { "com.company.mypackage" })
public class MyConfiguration implements ArangoConfiguration {

  @Override
  public ArangoDB.Builder arango() {
    return new ArangoDB.Builder();
  }

  @Override
  public String database() {
    // Name of the database to be used
    return "example-database";
  }

}

The driver configuration can be customized by implementing ArangoConfiguration#arango():

@Override
public ArangoDB.Builder arango() {
  return new ArangoDB.Builder()
      .host("127.0.0.1", 8529)
      .user("root")
      .password("xxx");
}

Note that, in case the driver is configured to use a protocol with VPACK content type (i.e. VST, HTTP_VPACK or HTTP2_VPACK), then the method ArangoConfiguration#contentType() must be overridden to return ContentType.VPACK, for example:

@Override
public ArangoDB.Builder arango() {
  new ArangoDB.Builder()
      // ...    
      .protocol(Protocol.HTTP2_VPACK);
}

@Override
public ContentType contentType() {
  return ContentType.VPACK;
}

You can use Java to configure your Spring Data environment as show below. Setting up the underlying driver (ArangoDB.Builder) with default configuration automatically loads a properties file arangodb.properties, if it exists in the classpath.

@Configuration
@EnableArangoRepositories(basePackages = { "com.company.mypackage" })
public class MyConfiguration implements ArangoConfiguration {

  @Override
  public ArangoDB.Builder arango() {
    return new ArangoDB.Builder();
  }

  @Override
  public String database() {
    // Name of the database to be used
    return "example-database";
  }

}

The driver is configured with some default values:

property-keydescriptiondefault value
arangodb.hostArangoDB host127.0.0.1
arangodb.portArangoDB port8529
arangodb.timeoutsocket connect timeout(millisecond)0
arangodb.userBasic Authentication User
arangodb.passwordBasic Authentication Password
arangodb.useSsluse SSL connectionfalse

To customize the configuration, the parameters can be changed in the Java code.

@Override
public ArangoDB.Builder arango() {
  ArangoDB.Builder arango = new ArangoDB.Builder()
    .host("127.0.0.1")
    .port(8529)
    .user("root");
  return arango;
}

In addition you can use the arangodb.properties or a custom properties file to supply credentials to the driver.

Properties file

arangodb.hosts=127.0.0.1:8529
arangodb.user=root
arangodb.password=

Custom properties file

@Override
public ArangoDB.Builder arango() {
  InputStream in = MyClass.class.getResourceAsStream("my.properties");
  ArangoDB.Builder arango = new ArangoDB.Builder()
    .loadProperties(in);
  return arango;
}

Using the underlying Java Driver

The underlying Java driver can be obtained via ArangoOperations.driver(). This driver instance is configured by default to use ArangoConverter bean to serialize and deserialize user data, therefore keeping the same Spring Data ArangoDB serialization behavior.

Spring Boot

Spring Boot support is offered by Spring Boot Starter ArangoDB .
