Using Java to Operate ArangoDB
To operate ArangoDB using Java, you first need to add the Java driver dependency of ArangoDB. Typically, in Maven projects, this can be achieved by adding the following dependencies to the pom.xml file of the project:
<dependency>
<groupId>com.arangodb</groupId>
<artifactId>arangodb-java-driver</artifactId>
<version>7.12.0</version>
</dependency>
Next, you can use the following sample code to demonstrate how to use Java operations on ArangoDB for data insertion, modification, query, and deletion:
import com.arangodb.ArangoDB;
import com.arangodb.ArangoDBException;
import com.arangodb.entity.BaseDocument;
import com.arangodb.entity.CollectionEntity;
import com.arangodb.model.CollectionCreateOptions;
public class ArangoDBExample {
public static void main(String[] args) {
//Connect to ArangoDB database
ArangoDB arangoDB = new ArangoDB.Builder()
.host("localhost", 8529)
. user ("username")//Optional: If the username and password for the database are set
.password("password")
.build();
try {
String dbName = "mydb";
String collectionName = "mycollection";
//Create Database
arangoDB.createDatabase(dbName);
//Using a database
arangoDB.db(dbName).createCollection(collectionName);
//Insert Document
BaseDocument document = new BaseDocument();
document.setKey("mykey");
document.addAttribute("name", "John Doe");
document.addAttribute("age", 30);
arangoDB.db(dbName).collection(collectionName).insertDocument(document);
//Modifying Documents
document.updateAttribute("age", 31);
arangoDB.db(dbName).collection(collectionName).updateDocument("mykey", document);
//Query Document
BaseDocument result = arangoDB.db(dbName).collection(collectionName).getDocument("mykey", BaseDocument.class);
System.out.println("Name: " + result.getAttribute("name"));
System.out.println("Age: " + result.getAttribute("age"));
//Delete Document
arangoDB.db(dbName).collection(collectionName).deleteDocument("mykey");
//Delete Database
arangoDB.db(dbName).drop();
} catch (ArangoDBException e) {
System. err. println ("ArangoDB operation error:"+e.getMessage ());
} finally {
//Close ArangoDB connection
arangoDB.shutdown();
}
}
}
This example shows how to use Java to connect to ArangoDB, create a database and collection, insert a document, modify it, query it, and finally delete it. You can modify the code according to your own needs to achieve other operations or functions.
Please ensure to replace 'localhost' with the host address of your ArangoDB instance and '8529' with the port number of your ArangoDB instance. Additionally, if your ArangoDB instance requires a username and password for authentication, please change 'username' and 'password' to the actual username and password.
