Changes looks good to me.

but there are few things need to be discuss before merge it:

• are we going to disable travis-ci (it doesn't make sense to have both them, it will waste resource and time)
• what platform do we use? I prefer linux-jdk8 and linux-jdk11. maybe windows too. but for macos, the lack of action runner will lead a long time to wait
• different concurrency limit between github action and travis ci (refer to https://www.mail-archive.com/builds@apache.org/msg07478.html)

hi, @htynkn

what platform do we use? I prefer linux-jdk8 and linux-jdk11. maybe windows too. but for macos, the lack of action runner will lead a long time to wait

yeap, I agree with you. I will disable macOS test case later on.

different concurrency limit between github action and travis ci (refer to https://www.mail-archive.com/builds@apache.org/msg07478.html)

According to Github Community, we can use at least up to 20 workflows concurrently for dubbo repo itself. For now it is enough for our building rate on travis.

DirtiesContext has been added to all of the test classes in dubbo-config-spring module. In different platform, the exection order of test cases is different and this may causes environment pollution. DirtiesContext can fix it.

[htynkn]

thanks for your investigate and contribution.

Will merge this change to master soon.
At this stage, I can see some duplicate code in github action yml file, maybe we can use some feature like matrix to make it more clean. those stuff can be done in the future.
