问题描述
我对使用PropertyPlaceholderConfigurer的Spring有一个奇怪的问题.我的一颗豆的设计如下:
I have a strange problem with Spring using PropertyPlaceholderConfigurer. One of my beans is designed as follow :
<bean name="propertyPlaceholder" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<value>classpath:jdbc.properties</value>
</property>
</bean>
问题是spring永远找不到jdbc.properties(FileNotFoundException).该文件位于捆绑包类路径中的名为"resources"的文件夹中(我在OSGi项目中工作).
The problem is that spring never find jdbc.properties (FileNotFoundException). The file is in a folder named "resources" that is in the bundle classpath (I am working in a OSGi project).
我尝试了几乎所有组合("jdbc.properties"，"/jdbc.properties"，"classpath:jdbc.properties"，"classpath:/jdbc.properties"，"/resources/jdbc.properties"等) ...)，但是它永远都行不通.
I have tried almost every combination ("jdbc.properties", "/jdbc.properties", "classpath:jdbc.properties", "classpath:/jdbc.properties", "/resources/jdbc.properties", etc...) but it never works.
有关信息，如果有的话，我会做类似的事情:
For information, if at some point, I do something like :
URL u = someClassLoader.getResource("jdbc.properties");
它确实可以正常工作并找到文件.实际上，我完全无法理解spring的错误.
it does work without any problem and find the file. Actually I am totally unable to understand what is the bug with spring.
如果您有任何帮助的想法，请先谢谢.我在春天不是很有经验，所以我可能在某个地方犯了一个错误.
If you have any idea to help me, thanks in advance. I am not very experienced in spring so I have maybe done a mistake somewhere.
实际上，这是类加载器的问题:如果我这样做:
Actually, it's a problem of classloader :If I do :
new ClassPathResource("jdbc.properties");
它不起作用.但是:
new ClassPathResource("jdbc.properties",someClassIntheBundle.class.getClassLoader());
工作完美.
我确实相信Spring使用它自己的包所消耗的ClassLoader.您知道解决这个棘手问题的方法吗?
I do believe that Spring use the ClassLoader of its own bundle that is consumed by my bundle. Do you know a way to solve this tricky problem ?
谢谢
推荐答案
尝试classpath*:jdbc.properties
