How to set spring bean properties in a .properties resource file

Is this possible to se开发者_如何学Got a spring bean's properties through a dot notation in a .properties file. For example suppose you have defined:

<bean name="myBean" class="MyBean" />

Is it possible to set MyBean.someProperty of myBean to a value defined in a properties file? For example by this properties file:

myBean.someProperty = aValue

I know about PropertyPlaceholderConfigurer, but my requirement is somewhat different from what it supports.

If you have a property in your xml like that, you can assign a value from a properties file like that

<property name="someProperty" value="${myBean.someProperty}" />

which has to deal with the PropertyPlaceholderConfigurer

But I think, you want to override your properties, so have a look at the documentation of the PropertyOverrideConfigurer

---

<context:property-placeholder location="classpath:/application.properties" />

<property name="myProperty" value="${myProperty.key.of.properties}" />

There's also a PropertyOverrideConfigurer available in the Spring distribution which does exactly what you're looking for.
