Simple spring JDBC example

This page gives simple JDBC example using spring. We are using MySQL database here.

pom.xml file gives all required dependencies:

<project xmlns="" 

Employee model class:

package com.java2novice.model;

public class Employee {

        private int empId;
        private String name;
        private int salary;
        private String dept;
        public int getEmpId() {
                return empId;
        public void setEmpId(int empId) {
                this.empId = empId;
        public String getName() {
                return name;
        public void setName(String name) {
       = name;
        public int getSalary() {
                return salary;
        public void setSalary(int salary) {
                this.salary = salary;
        public String getDept() {
                return dept;
        public void setDept(String dept) {
                this.dept = dept;

Employee DAO interface:

package com.java2novice.dao;

import com.java2novice.model.Employee;

public interface EmployeeDao {

        public Employee findEmployeeById(int empId);

Employee DAO implementation class:

package com.java2novice.dao;

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

import javax.sql.DataSource;

import com.java2novice.model.Employee;

public class EmployeeDaoImpl implements EmployeeDao{

        private DataSource dataSource;
        public void setDataSource(DataSource dataSource) {
                this.dataSource = dataSource;
        public Employee findEmployeeById(int empId) {
                Employee emp = null;
                String query = "select * from employee where emp_id=?"; 
                Connection conn = null;
                PreparedStatement prepStmt = null;
                ResultSet rsltSet = null;
                try {
                        conn = dataSource.getConnection();
                        prepStmt = conn.prepareStatement(query);
                        prepStmt.setInt(1, empId);
                        rsltSet = prepStmt.executeQuery();
                        emp = new Employee();
                } catch (SQLException e) {
                        // TODO Auto-generated catch block
                } finally {
                        try {
                                if(rsltSet != null) rsltSet.close();
                                if(prepStmt != null) prepStmt.close();
                        } catch(Exception ex){}
                return emp;


Here is the xml based configuration file, look at mysql DB configurations:

<beans xmlns=""

    <bean id="dataSource"
                <property name="driverClassName" value="com.mysql.jdbc.Driver" />
                <property name="url" value="jdbc:mysql://localhost:3306/java2novice" />
                <property name="username" value="user_name" />
                <property name="password" value="password" />
    <bean id="employeeDAO" class="com.java2novice.dao.EmployeeDaoImpl">
                <property name="dataSource" ref="dataSource" />

Here is the final demo class:

package com.java2novice.test;

import org.springframework.context.ConfigurableApplicationContext;

import com.java2novice.dao.EmployeeDao;
import com.java2novice.model.Employee;

public class SpringDemo {

        public static void main(String a[]){
                String confFile = "applicationContext.xml";
                ConfigurableApplicationContext context = 
                                                                        new ClassPathXmlApplicationContext(confFile);
                EmployeeDao empDao = (EmployeeDao) context.getBean("employeeDAO");
                Employee emp = empDao.findEmployeeById(1);
                System.out.println(emp.getName()+" | "+emp.getSalary()+" | "+emp.getDept());

Knowledge Centre
Exception Vs Error
An error is an irrecoverable condition occurring at runtime like out of memory error. These kind of jvm errors cannot be handled at runtime. Exceptions are because of condition failures, which can be handled easily at runtime.
Famous Quotations
The very best thing you can do for the whole world is to make the most of yourself.
