ArangoOperations interface provides insert method to insert multiple documents.

Signature

 MultiDocumentEntity extends DocumentEntity> insert(Iterable values, Class entityClass, DocumentCreateOptions options) throws DataAccessException;

 MultiDocumentEntity extends DocumentEntity> insert(Iterable values, Class entityClass) throws DataAccessException;

Creates new documents from the given documents, unless there is already a document with the _key given. If no _key is given, a new unique _key is generated automatically.

‘DocumentCreateOptions’ parameter is used to provide additional options while creating the documents.

Following table summarizes different options that are provided using ‘DocumentCreateOptions’.

Example

MultiDocumentEntity multiDocuments = (MultiDocumentEntity) arangoTemplate.insert(Arrays.asList(emp1, emp2, emp3), Employee.class, docCreateOptions);

Find the below working application.

Step 1: Create new maven project ‘arango-template-create-documents’.

Step 2: Update pom.xml with maven dependencies.

project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Step 3: Define Employee entity class.

package com.sample.app.entity;

import org.springframework.data.annotation.Id;

import com.arangodb.springframework.annotation.ArangoId;
import com.arangodb.springframework.annotation.Document;

@Document("employees")
public class Employee {

@Id // db document field: _key
private String key;

@ArangoId // db document field: _id
private String arangoId;

private Integer id;
private String firstName;
private String lastName;
private Integer age;

public Employee() {

	}

public Employee(Integer id, String firstName, String lastName, Integer age) {
super();
this.id = id;
this.firstName = firstName;
this.lastName = lastName;
this.age = age;
	}

public String getKey() {
return key;
	}

public void setKey(String key) {
this.key = key;
	}

public String getArangoId() {
return arangoId;
	}

public void setArangoId(String arangoId) {
this.arangoId = arangoId;
	}

public Integer getId() {
return id;
	}

public void setId(Integer id) {
this.id = id;
	}

public String getFirstName() {
return firstName;
	}

public void setFirstName(String firstName) {
this.firstName = firstName;
	}

public String getLastName() {
return lastName;
	}

public void setLastName(String lastName) {
this.lastName = lastName;
	}

public Integer getAge() {
return age;
	}

public void setAge(Integer age) {
this.age = age;
	}

@Override
public String toString() {
return "Employee [id=" + id + ", firstName=" + firstName + ", lastName=" + lastName + ", age=" + age + "]";
	}

}

Step 4: Define arango db configuration class.

ArangoConfig.java

package com.sample.app.config;

import org.springframework.context.annotation.Configuration;

import com.arangodb.ArangoDB;
import com.arangodb.springframework.annotation.EnableArangoRepositories;
import com.arangodb.springframework.config.ArangoConfiguration;

@Configuration
@EnableArangoRepositories(basePackages = { "com.sample.app" })
public class ArangoConfig implements ArangoConfiguration {

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

@Override
public String database() {
return "abc_org";
	}
}

Step 5: Define main application class.

package com.sample.app;

import java.util.Arrays;
import java.util.Collection;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;

import com.arangodb.entity.DocumentCreateEntity;
import com.arangodb.entity.MultiDocumentEntity;
import com.arangodb.model.DocumentCreateOptions;
import com.arangodb.springframework.core.ArangoOperations;
import com.sample.app.entity.Employee;

@SpringBootApplication
public class App {

@Autowired
private ArangoOperations arangoTemplate;

public static void main(String args[]) {
		SpringApplication.run(App.class, args);
	}

@Bean
public CommandLineRunner demo() {

return (args) -> {

			Employee emp1 = new Employee(1, "Ram", "Gurram", 31);
			Employee emp2 = new Employee(2, "Sailaja", "Ptr", 33);
			Employee emp3 = new Employee(3, "Sravya", "Y", 85);

			DocumentCreateOptions docCreateOptions = new DocumentCreateOptions();
			docCreateOptions.returnNew(true);

			MultiDocumentEntity multiDocuments = (MultiDocumentEntity) arangoTemplate
					.insert(Arrays.asList(emp1, emp2, emp3), Employee.class, docCreateOptions);

			Collection documentCreateEntities = multiDocuments.getDocuments();

			System.out.println("Created documents");
for (DocumentCreateEntity docCreateEntity : documentCreateEntities) {
				System.out.println("\nid : " + docCreateEntity.getId());
				System.out.println("key : " + docCreateEntity.getKey());
				System.out.println("revision : " + docCreateEntity.getRev());
				System.out.println("doc : " + docCreateEntity.getNew());
			}

		};
	}
}

Total project structure looks like below.

Run App.java, you will see below messages in console.
