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:
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-key | description | default value |
---|---|---|
arangodb.host | ArangoDB host | 127.0.0.1 |
arangodb.port | ArangoDB port | 8529 |
arangodb.timeout | socket connect timeout(millisecond) | 0 |
arangodb.user | Basic Authentication User | |
arangodb.password | Basic Authentication Password | |
arangodb.useSsl | use SSL connection | false |
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 .
