Spring SimpleJdbcTemplate batchUpdate() example

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

See batchUpdate() example in SimpleJdbcTemplate class.

//insert batch examplepublic 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 SQLpublic 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.
