1. beans

这里有两个 beans, 分别是：developer 和 language

package com.h3.common;

public class developer {
	private language language;

	//autowire by constructor
	public developer(language language) {
		this.language = language;
	}

	//...

}

package com.h3.common;

public class language {
	private string name;
	//...
}

2. spring装配

<bean id="developer" class="com.h3.common.developer">
		<constructor-arg>
			<ref bean="language" />
		</constructor-arg>
	</bean>
		
	<bean id="language" class="com.h3.common.language" >
		<property name="name" value="java" />
	</bean>

输出

developer [language=language [name=java]]

<bean id="developer" class="com.h3.common.developer" autowire="constructor" />
		
	<bean id="language" class="com.h3.common.language" >
		<property name="name" value="java" />
	</bean>

输出

developer [language=language [name=java]]
