Spring data source C3P0

In this section, we will discuss about Spring data source C3P0 and it's implementation with example.

Spring data source C3P0

In Spring , we connect to a database via data source. When we are using jdbc layer in Spring , JNDI provide us data source or you can configure your own data source by implementing connection pool , provided by a third party. One of the most famous implementations are Apache Jakarta Commons DBCP and C3P0.The "DriverManagerDataSource" perform poorly when multiple requests for a connection are made.

In the below example , we are using data source c3p0 to create a database table & insert value using jdbcTemplate. You can download c3p0 from below given link :

C3P0 Configuration (xml file):

<bean id="dataSource"
class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
<property name="driverClass" value="${jdbc.driverClassName}"/>
<property name="jdbcUrl" value="${jdbc.url}"/>
<property name="user" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
<context:property-placeholder location=""/>

package net.roseindia;

import javax.sql.DataSource;
import org.springframework.jdbc.core.JdbcTemplate;

public class CreateTable {
    private JdbcTemplate jdbcTemplate;

    public void setDataSource(DataSource dataSource) {
    this.jdbcTemplate = new JdbcTemplate(dataSource);

    public void doExecute() {
    this.jdbcTemplate.execute("create table mytable(id integer, name varchar(100))");
    public void doInsert() {
    this.jdbcTemplate.update("insert into mytable(id, name) values (?, ?)",1, "Ankit");

package net.roseindia;

import org.springframework.beans.factory.xml.XmlBeanFactory;


public class MainCreateTable {

public static void main(String[] args) {
XmlBeanFactory beanFactory = new XmlBeanFactory(new ClassPathResource("DataTable.xml")) ;

CreateTable myBean =(CreateTable) beanFactory.getBean("CreateTable");


<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns=""
xmlns:xsi="" xmlns:context=""
<bean id="CreateTable" class="net.roseindia.CreateTable">
<property name="dataSource" ref="dataSource" />
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
<property name="driverClass" value="com.mysql.jdbc.Driver" />
<property name="jdbcUrl" value="jdbc:mysql://" />
<property name="user" value="root" />
<property name="password" value="root" />
<context:property-placeholder location="" />
