unzip the file.

Configuration of spring in Eclipse IDE
Follow the steps to create a simple Java project –
I. Create Java Project
In Eclipse IDE > File > New > others > search Java Project > select Next

1. Write Project name

2. ​Take the proper JRE file location option > select Finish

II. Add Required Libraries

1. Add common logging API libraries

   Right click current Java Project > select Properties > select Java Build Path
   Add External JARs as shown below

1. Add Spring Libraries
   Go to Add libraries > User Library > User Libraries > New
   Write Spring Jars > in User Libraries & add External JARs

Apply and say ok to finish the setting up of jar files

III. Create Source Files
Package com.bean.User class

 package com.bean;
public class User {
String name;
int age;
//Setter & Getter

Package com.main.MainClass java class

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.bean.User;
public class MainClass {
public static void main(String[] args) {
ApplicationContext context =
new ClassPathXmlApplicationContext("SpringConfig.xml");
User user= (User) context.getBean("userbean");
System.out.println("Name: "+ user.getName());
System.out.println("Age: "+ user.getAge());
}
}

SpringConfig.xml​​

<?xml version="1.0" encoding="UTF-8"?>
<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-3.0.xsd">
<bean id = "userbean" class = "com.bean.User">
<property name = "name" value = "Atindra"/>
<property name = "age" value = "24"/>
</bean>
</beans>
