本文介绍了春季手动销毁bean而不是ctx.close()的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
是否可以告诉spring的容器销毁特定的bean(原型)以节省内存?
is it possible to tell the container of spring to destroy a specific bean (prototype) in order to save up memory?
我不想使用ctx.close()来查看此bean被销毁，而是在运行时.
I dont want to user ctx.close() in order to see this bean destroyed, but rather on runtime.
推荐答案
如果我正确理解了您想删除运行时在ctx中定义的bean，我将使用BeanDefinitionRegistry完成此操作，BeanDefinitionRegistry有一个removeBean()方法，该方法以bean名称作为参数.
If I understand you correctly you want to remove bean that was defined in the ctx at runtime, will I use BeanDefinitionRegistry to get this done, BeanDefinitionRegistry has a method of removeBean() which takes the bean name as the parameter.
BeanDefinitionRegistry factory =
(BeanDefinitionRegistry) applicationCtx.getAutowireCapableBeanFactory();
然后
((DefaultListableBeanFactory) beanFactory).destroySingleton("myBean");
