Spring getBean方法源码解析

User user = (User) beanFactory.getBean("user");

注：User为一普通bean
查看方法（AbstractBeanFactory#getBean）
public Object getBean(String name) throws BeansException {
return doGetBean(name, null, null, false);
}

继续查看方法（AbstractBeanFactory#doGetBean）
protected T doGetBean(final String name, @Nullable final Class requiredType,
@Nullable final Object[] args, boolean typeCheckOnly
