I tried all the options that I could find anywhere, I looked at all the questions asked earlier on this topic, and tried the solutions given in them, but nothing worked, all I get is an error.

The files created in this example are shown below.
spring.xml This is a schema definition
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
This is the place I want to apply automatically.
<bean id="circle" class="spring.springdemo.Circle"> </bean> <bean id="pointA" class="spring.springdemo.Point"> <qualifier value="CircleRelated"/> <property name="x" value="0"/> <property name="y" value="0"/> </bean> <bean id="pointB" class="spring.springdemo.Point"> <property name="x" value="-20"/> <property name="y" value="0"/> </bean> <bean id="pointC" class="spring.springdemo.Point"> <property name="x" value="20"/> <property name="y" value="0"/> </bean>
These are the classes that I added.
<bean class="org.springframework.beans.factory.annotation.QualifierAnnotationAutowireCandidateResolver"/> <bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>
Circle.java object class, thats will be filled by autwire
import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Qualifier; public class Circle implements Shape{ private Point center; @Override public void draw() { System.out.println("Drawing Circle"); System.out.println("Point is : ("+center.getX()+", "+center.getY()+")"); } public Point getCenter() { return center; } @Autowired @Qualifier("CircleRelated") public void setCenter(Point center) { this.center = center; } }
