I have written a small code to check @Autowired annotation in Spring, here is my piece of code.
package beans;
//import org.springframework.beans.factory.annotation.AutoWired;
import org.springframework.beans.factory.annotation.Autowired;
//import org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor;
import org.springframework.beans.factory.annotation.Qualifier;
//import org.springframework.beans.factory.annotation.*;
public class Car {
@Autowired
@Qualifier(value="e1")
private Engine engine;
//no need to have setters or constructors here
public void printData()
{
System.out.println("Engine model year: " +engine.getModelyear());
}
}
package beans;
public class Engine {
private String modelyear;
//generate setter and getter
public void setModelyear(String modelyear) {
this.modelyear = modelyear;
}
public String getModelyear() {
return modelyear;
}
}
package test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import beans.Car;
//import beans.Test;
public class Client {
/**
* @param args
*/
public static void main(String[] args) {
ApplicationContext ap = new ClassPathXmlApplicationContext("resource/spring.xml");
Car c=(Car)ap.getBean("c");
c.printData();
}
}
<!--spring.xml-->
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN"
"http://www.springframework.org/dtd/spring-beans-2.0.dtd">
<beans>
<!-- activate autowire annotation -->
<bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>
<bean id="engine" class="beans.Engine">
<property name="modelyear" value="2015"/>
</bean>
<bean id="e1" class="beans.Engine">
<property name="modelyear" value="2016"/>
</bean>
<bean id="c" class="beans.Car">
</bean>
</beans>
When I am trying to run Client.java class ,I am getting following error: Can someone suggest why I am facing this issue?
