请教一个关于spring加载properties的问题。

我在spring配置中配置了 PropertyPlaceholderConfigurerrn rn rn rn classpath:xxxx.propertiesrn rn rn rnrn在其他地方使用$xx.xxx来读取properties中的内容。rn而且我需要在网页上修改xxxx.properties的内容，然后保存，并且希望在以后加载bean的时候使用修改后的属性。rnrn现在的问题是，我一修改保存xxxx.properties，spring就去重新加载所有的bean，几百个，搞半天，但是实际上只影响到几个bean而已，请问这个问题怎么解决啊。
