我需要在启动时将application-test.properties路径设为100％唯一，以进行Spring Boot单元测试

Question

I need to make an application-test.properties path 100% unique at startup for a spring boot unit test.

I was thinking I could use the current time in milliseconds, or a generated UUID, but I don't know how I would do that from within a properties file.

I'm using some of the jenkins variables plus some defaults for local testing to get it closer, but it's not 100% certain due to the way the pipeline was set up.

Current application-test.properties:

data.path=tmp/Bob/test-${BRANCH_NAME:local}-${BUILD_ID:local}/source

I'm looking for something like this:

data.path=tmp/Bob/test-${BRANCH_NAME:local}-${BUILD_ID:local}-${UUID.randomUUID().toString())}/source

or

data.path=tmp/Bob/test-${BRANCH_NAME:local}-${BUILD_ID:local}-${System.currentTimeMillis()}/source

or something similar.

Note: I can't mess with the pipeline at this time, or I'd just create a variable for this purpose.

Spring boot provides a random property source . This lets you inject random ints, longs, and even UUIDs into your properties.
