only one PropertyPlacholderConfigurer?

[raysuliteanu]

I have several different modules packaged in jars, where each has its own Spring config and its own PropertyPlaceholderConfigurer, declared via the context namespace. I then have an integration test that is loading all the application contexts via the classpath. It appears that only one (the last? the first?) PropertyPlaceholderConfigurer is found.

Specifically:

module1-context.xml

<context:property-placeholder system-properties-mode = "OVERRIDE" location = "classpath:module1.properties"/>

module2-context.xml

<context:property-placeholder system-properties-mode = "OVERRIDE" location = "classpath:module2.properties"/>

module3-context.xml

<context:property-placeholder system-properties-mode = "OVERRIDE" location = "classpath:module3.properties"/>

integration test:

@ContextConfiguration({"classpath:main.xml", "classpath*:*-context.xml"})
public class MyTest extends AbstractJUnit4SpringContextTests {

when I run the test, it loads properties from one of the modules, but fails to load the others.

I see debug log messages that the beans were found, but only one log message from PropertyPlaceholderConfigurer itself that it's loaded the properties file.

any thoughts? this is Spring 3.0.5.

My bad (of course) ... forgot to add ignore-unresolvable = "true" so that as Spring iterates over each PropertyPlaceholderConfigurer if the current one can't find the property it won't fail, but rather let Spring move on to the next one.
