Issue
I am trying to learn the basic of the Spring framwork. I am using the org.springframework.beans.factory.config.PropertyPlaceholderConfigurer
in the sping.xml to print the properties of the PointA but I am getting the error below.
package org.stack;
import java.util.List;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.BeanNameAware;
import org.springframework.beans.factory.DisposableBean;
import org.springframework.beans.factory.InitializingBean;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
public class Triangle {
private Point PointA;
private Point PointB;
private Point PointC;
private ApplicationContext context = null;
public Point getPointA() {
return PointA;
}
public void setPointA(Point pointA) {
PointA = pointA;
}
public Point getPointB() {
return PointB;
}
public void setPointB(Point pointB) {
PointB = pointB;
}
public Point getPointC() {
return PointC;
}
public void setPointC(Point pointC) {
PointC = pointC;
}
public void draw() {
System.out.println("Point A = (" + getPointA().getX() + ", "
+ getPointA().getY() + ")");
System.out.println("Point B = (" + getPointB().getX() + ", "
+ getPointB().getY() + ")");
System.out.println("Point C = (" + getPointC().getX() + ", "
+ getPointC().getY() + ")");
}
}
DrawingApp
package org.stack;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class DrawingApp {
public static void main(String[] args) {
AbstractApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");
context.registerShutdownHook();
Triangle triangle = (Triangle) context.getBean("triangle");
triangle.draw();
}
}
spring.xml
</bean>
<!-- We intialize here 3 Points objects -->
<bean id="pointA" class="org.stack.Point">
<property name="x" value="${PointA.pointY}" />
<property name="y" value="${PointA.pointY}" />
