Can Spring Parse and Inject Properties Files?
提问by Garth Gilmour
I already know how to:
我已经知道如何：
Load properties files into my Spring configuration using:
使用以下命令将属性文件加载到我的 Spring 配置中：
<context:property-placeholder location="aaa/bbb/ccc/stuff.properties"/>
Build properties objects on the fly using:
使用以下方法即时构建属性对象：
<props><prop key="abc">some value</prop></props>
But what I cant do, and would be really useful, is to have Spring load a properties file and then build the matching properties object. I could then inject this into a bean in the normal way.
但是我不能做的并且非常有用的是让 Spring 加载一个属性文件，然后构建匹配的属性对象。然后我可以以正常方式将其注入到 bean 中。
I've searched for this elsewhere without success. Any ideas?
我在别处搜索过这个，但没有成功。有任何想法吗？

Take a look at util:properties
<util:properties id="myProperties" location="classpath:com/foo/my.properties"/>
Then, to inject the Properties into your Spring-managed Bean, it's as simple as this:
然后，要将属性注入到 Spring 管理的 Bean 中，就像这样简单：
@Resource(name = "myProperties")
private Properties myProperties;
