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 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 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;
}
