使用编码方式创建和绑定Bean

package com.astute.sparrow.spring.ioc.test;

public class B {
	
	public void output() {
		System.out.println("B.output");
	}
	
}

package com.astute.sparrow.spring.ioc.test;

public class A {
	private B b;

	public A() {
	}

	public A(B b) {
		super();
		this.b = b;
	}

	public B getB() {
		return b;
	}

	public void setB(B b) {
		this.b = b;
	}
	
}

//创建Bean工厂
		DefaultListableBeanFactory factory = new DefaultListableBeanFactory();
		
		//生成BeanDefinition
		AbstractBeanDefinition newA = new RootBeanDefinition(A.class);
		newA.setScope(BeanDefinition.SCOPE_SINGLETON);
		AbstractBeanDefinition newB = new RootBeanDefinition(B.class);
		newB.setScope(BeanDefinition.SCOPE_PROTOTYPE);
		
		//注册
		factory.registerBeanDefinition("a", newA);
		factory.registerBeanDefinition("b", newB);
		
		//功过构造函数注入
		ConstructorArgumentValues argValues = new ConstructorArgumentValues();
		argValues.addIndexedArgumentValue(0, newB);
		newA.setConstructorArgumentValues(argValues);
		
		//通过Setter方式注入
		MutablePropertyValues propertyValues = new MutablePropertyValues();
		propertyValues.addPropertyValue(new PropertyValue("b", newB));
		newA.setPropertyValues(propertyValues);
		
		A a = (A) factory.getBean("a");
		a.getB().output();
