Make Eclipse use src/test/resources instead of src/main/resources

I'm writing a little Maven application in Ecl开发者_运维百科ipse. I store some property files and my application context in the directory src/main/resources.

I now want to make Eclipse use properties in the directory src/test/resources. So when I run and debug the program in Eclipse, these test properties should be used.

Do you know how I could make that happen?

Try this:

1. Go to "Run->Run configurations..." (in case of debug "Run->Debug configurations...")
2. Open Run (Debug) configuration which you use
3. Open "Classpath" tab
4. Select "User Entries" and click "Advanced..." on the right
5. In the opened window select "Add folder", point to your src/test/resources
6. This folder will appear under "User entries", then you should move it up to make it the first on your classpath

Whether you use the Maven Eclipse Plugin or m2eclipse, src/test/resources precedes src/main/resources on the classpath (more precisely, their output directories). In other words, there is nothing to do, things just works as on the command line.

Use a test override (e.g. testOverrides.xml):

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <!--  this file need to be imported before other contexts to ensure the test properties take effect -->

    <context:property-placeholder location="classpath*:META-INF/spring/testproperties/*.properties"/>

</beans>

In your tests, make sure it's imported first:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath*:META-INF/spring/testOverrides.xml","classpath*:META-INF/spring/applicationContext.xml"})
public class SomeTest { ... }

Now put all your test properties in src/test/resources/META-INF/spring/testproperties/.

You have to also make sure that the main placeholder configurer doesn't ever see testproperties, e.g. here's mine:

<context:property-placeholder location="classpath*:META-INF/spring/*.properties"/>

It doesn't use the double-* wildcard, so will only look at that one directory.

I use the above method with great success.

Tested in eclipse 2021. Go to Run As Configuration (or debug) and go to Classpath tab. Now you could check or uncheck, depends if you want to use /src/main/resources or /src/test/resources, like so:

Finaly, apply and run your program
