In this tutorial, we show you how to use batchUpdate() in SimpleJdbcTemplate class.

See batchUpdate() example in SimpleJdbcTemplate class.

//insert batch example

public void insertBatch(final List<Customer> customers){

	String sql = "INSERT INTO CUSTOMER " +

		"(CUST_ID, NAME, AGE) VALUES (?, ?, ?)";

	List<Object[]> parameters = new ArrayList<Object[]>();

	for (Customer cust : customers) {

        parameters.add(new Object[] {cust.getCustId(),

            cust.getName(), cust.getAge()}

        );

    }

    getSimpleJdbcTemplate().batchUpdate(sql, parameters);

}

Alternatively, you can execute the SQL directly.

//insert batch example with SQL

public void insertBatchSQL(final String sql){

	getJdbcTemplate().batchUpdate(new String[]{sql});

}

Spring’s bean configuration file

<beans xmlns="http://www.springframework.org/schema/beans"

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	xsi:schemaLocation="http://www.springframework.org/schema/beans

	http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

	<bean id="customerSimpleDAO"

        class="com.mkyong.customer.dao.impl.SimpleJdbcCustomerDAO">

		<property name="dataSource" ref="dataSource" />

	</bean>

	<bean id="dataSource"

        class="org.springframework.jdbc.datasource.DriverManagerDataSource">

		<property name="driverClassName" value="com.mysql.jdbc.Driver" />

		<property name="url" value="jdbc:mysql://localhost:3306/mkyongjava" />

		<property name="username" value="root" />

		<property name="password" value="password" />

	</bean>

</beans>

Run it

package com.mkyong.common;

import java.util.ArrayList;

import java.util.List;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.mkyong.customer.dao.CustomerDAO;

import com.mkyong.customer.model.Customer;

public class App

{

    public static void main( String[] args )

    {

    	ApplicationContext context =

    		new ClassPathXmlApplicationContext("Spring-Customer.xml");

        CustomerDAO customerSimpleDAO =

                      (CustomerDAO) context.getBean("customerSimpleDAO");

        Customer customer1 = new Customer(1, "mkyong1",21);

        Customer customer3 = new Customer(2, "mkyong2",22);

        Customer customer2 = new Customer(3, "mkyong3",23);

        List<Customer>customers = new ArrayList<Customer>();

        customers.add(customer1);

        customers.add(customer2);

        customers.add(customer3);

        customerSimpleDAO.insertBatch(customers);

        String sql = "UPDATE CUSTOMER SET NAME ='BATCHUPDATE'";

        customerSimpleDAO.insertBatchSQL(sql);

    }

}

In this example, you are inserted three customers’ records and update all customer’s name in batch.
