Create domain model

Create domain model named student. Here we are going to inject 2 properties via setter injection.

Consider the following Student bean class

package com.javatips;

public class Student {

 
private String name;
 
private int age;

 
public String getName() {
   
return name;
 
}

 
public void setName(String name) {
   
this.name = name;
 
}

 
public int getAge() {
   
return age;
 
}

 
public void setAge(int age) {
   
this.age = age;
 
}

 
public String toString() {
   
return "Student " + name + " is " + age + " years old";
 
}
}

beans.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.xsd">

    <bean id="student" class="com.javatips.Student">
        <property name="name" value="Rockey" />
        <property name="age" value="29" />
    </bean>

</beans>

Test Program

package com.javatips;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Main {

 
public static void main(String[] args) {
   
ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
    Student student =
(Student)context.getBean("student");
    System.out.println
(student);
 
}
}
Output
Student Rockey is 29 years old
