autowiring byName in spring

[deepak carter]

I am just starting up with Spring and trying autowiring byName here is my code

package org.springinaction;

public class Address 
{
	private String addressline;

	public String getAddressline() {
		return addressline;
	}

	public void setAddressline(String addressline) {
		this.addressline = addressline;
	}
	
}

package org.springinaction;

public class Customer
{
	private Address address;

	public Address getN() {
		return address;
	}

	public void setN(Address n) {
		this.address = n;
	}

	

		
}

springinaction.xml
<bean id="customer" class="org.springinaction.Customer" autowire="byName" >
</bean>
<bean id="address" class="org.springinaction.Address">
	<property name="addressline" value="bangalore" />
</bean>
</beans>


package org.springinaction;

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

public class CustomerTest {

	public static void main(String[] args) 
	{
		ApplicationContext context =new ClassPathXmlApplicationContext("SpringInAction.xml");
		Customer cust=(Customer)context.getBean("customer");
		System.out.println(cust.getN());
	}

}

Have you tried calling your set and get method setAddress and getAddress and the parameter for setAddress(Address address)

?

What Mark said will fix it.

Here is the reason behind it. Below is from Spring Framework 3.0.7 Reference.

Table 3.2. Autowiring modes
.
.
.
Mode: byName
.
.
Autowiring by property name. Spring looks for a bean with the same name as the property that needs to be autowired. For example, if a bean definition is set to autowire by name, and it contains a master property (that is, it has a setMaster(..) method), Spring looks for a bean definition named master, and uses it to set the property.
