Spring Example:
The Spring Framework represents a dependency injection /
inversion of control container framework for the Java platform. Furthermore
Spring offers a lot of additional functions.Spring framework was initially.
Written by Rod Johnson and was first released
under the Apache 2.0 license in June 2003.
Use Case:
Test Class - To
create a main class in eclips.
Triangle Class - To create getter and setter in Triangle
class.
Point Class - To create a point set the value.
Spring Class - To
create a beans
Test Java class:
package Tutorial;
import
org.springframework.beans.factory.BeanFactory;
import
org.springframework.context.ApplicationContext;
import
org.springframework.context.support.ClassPathXmlApplicationContext;
public class Test
{
public static void main(String[] args)
{
ApplicationContext aap=new
ClassPathXmlApplicationContext("spring.xml");
Triangle t=(Triangle)aap.getBean("tri");
t.draw();
}
}
Triangle class in Java:
package
Tutorial;
import java.util.List;
public class Triangle
{
Point point1;
Point point2;
Point point3;
public Point
getPoint1() {
return point1;
}
public void setPoint1(Point point1) {
this.point1 =
point1;
}
public Point getPoint2() {
return point2;
}
public void setPoint2(Point point2) {
this.point2 =
point2;
}
public Point getPoint3() {
return point3;
}
public void setPoint3(Point point3) {
this.point3 =
point3;
}
public void draw()
{
System.out.println("point1" + point1.getX()+"\tpoint2" + point1.getY());
}
}
Point Class in Java:
package
Tutorial;
public class Point {
int x;
int y;
public int getX() {
return x;
}
public void setX(int x) {
this.x = x;
}
public int getY() {
return y;
}
public void setY(int y) {
this.y = y;
}
}
Spring Class in Xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd"
