spring：如何用代码动态向容器中添加或移除Bean ？

先来看一张类图：

<?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"> 
<context:component-scan base-package="yjmyzz" />

</beans>

输出：
FooA is created!
FooA.foo()
class yjmyzz.FooA
fooA
true
FooA.destroy()
false
------------
FooB is created!
FooB.foo()
class yjmyzz.FooB
fooB
true
