spring-context.xml的位置

Question

When I run my application on tomcat the spring-context.xml file is located at

/WEB-inf/spring-context.xml

This is ok. But running a junit test I have to supply it with the location of my spring-test-context.xml like this:

@ContextConfiguration(locations={"classpath:/spring-test-context.xml"})

The only way this works is if the file is located in

/src/spring-context.xml

How can I get my application to find my spring-context files in the same location? So that it works with junit testes and deployed on tomcat?

I tried this and it gave me alot of errors about not finding any beans, but it didn't say it couldn't find the file..

classpath:/WEB-INF/spring-test-context.xml

As duffymo hinted at, the Spring TestContext Framework (TCF) assumes that string locations are in the classpath by default. For details, see the JavaDoc for ContextConfiguration .

Note, however, that you can also specify resources in the file system with either an absolute or relative path using Spring's resource abstraction (ie, by using the "file:" prefix). You can find details on that in the JavaDoc for the modifyLocations() method in Spring's AbstractContextLoader .

So for example, if your XML configuration file is located in "src/main/webapp/WEB-INF/spring-config.xml" in your project folder, you could specify the location as a relative file system path as follows:

@ContextConfiguration("file:src/main/webapp/WEB-INF/spring-config.xml")

As an alternative, you could store your Spring configuration files in the classpath (eg, src/main/resources ) and then reference them via the classpath in your Spring MVC configuration -- for example:

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:/spring-config.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

With this approach, your test configuration would simply look like this (note the leading slash that denotes that the resource is in the root of the classpath):

@ContextConfiguration("/spring-config.xml")

You might also find the Context configuration with XML resources section of the reference manual useful.

The problem is that /WEB-INF is not in the CLASSPATH for a web app. However, /WEB-INF/classes is.

Your problem with testing is that you aren't running in an app server, so WEB-INF/classes isn't part of the CLASSPATH by default. I'd recommend setting up your tests so that either WEB-INF/classes is in the test CLASSPATH or use a relative or absolute file path to find them.
