[英]Spring inside war cannot find classpath resource in an inner jar file
I have a project organized like this: 我有一个像这样组织的项目:
core
-- /src/main/resources/company/config/spring-config.xml
webapp
-- /WEB-INF/applicationContext.xml
The webapp depends on core.jar
, which is included correctly in WEB-INF/lib
when I deploy. webapp依赖于
core.jar
,我在部署时正确地包含在WEB-INF/lib
。
In web.xml
I have: 在
web.xml
我有:
<param-value>
/WEB-INF/applicationContext.xml
</param-value>
And in applicationContext.xml
I have: 在
applicationContext.xml
我有:
<import resource="classpath:/company/config/spring-config.xml" />
But when I run, I get this error: 但是当我跑步时,我收到了这个错误:
2012-10-04 20:03:39,156 [localhost-startStop-1] springframework.web.context.ContextLoader ERROR: Context initialization failed

When spring-config.xml
is in webapp, everything works fine. 当
spring-config.xml
在webapp中时,一切正常。
I noticed the leading /
is removed from some of the errors on the stack trace, and I wonder if this has anything to do with it. 我注意到的领先
/
从一些堆栈跟踪误差的去除,我不知道这有什么用它做。
Also, I am (unfortunately) using Spring 2.5, if that matters. 另外,我(不幸的是)使用Spring 2.5,如果这很重要的话。
For future reference, I figured out the problem after much debugging. 为了将来参考,我经过多次调试后想出了问题。 It turns out Eclipse was building my "core" library as a jar, but with a web application package layout, so instead of my resource being located here:
事实证明Eclipse正在将我的“核心”库构建为jar,但是使用Web应用程序包布局,因此我的资源不在此处:
/company/config/spring-config.xml
it was located here: 它位于这里:
/WEB-INF/company/config/spring-config.xml
which caused the problem. 这引起了这个问题。 I had checked the jar a few times before, but had never noticed the sneaky "/WEB-INF" hiding in plain sight.
我曾经几次检查过这个罐子,但从来没有注意到偷偷摸摸的“/ WEB-INF”隐藏在视线之内。
Removing the project and re-importing it into Eclipse (via the Maven pom.xml file) was not enough to fix the problem. 删除项目并将其重新导入Eclipse(通过Maven pom.xml文件)还不足以解决问题。
I had to manually delete the Eclipse-specific .project, .classpath, and .settings files. 我不得不手动删除特定于Eclipse的.project,.classpath和.settings文件。 When I did that and re-imported the project everything was fixed.
当我这样做并重新导入项目时,一切都得到了修复。
The moral of the lesson is: ALWAYS check your resource paths when the exception says "File Not Found". 本课程的寓意是:当异常显示“找不到文件”时, 总是检查资源路径。
