ASF GitHub Bot commented on SCB-243: ------------------------------------ WillemJiang closed pull request #136: SCB-243 able to intercept old java chassis requests URL: https://github.com/apache/incubator-servicecomb-saga/pull/136 This is a PR merged from a forked repository. As GitHub hides the original diff on merge, it is displayed below for the sake of provenance: As this is a foreign pull request (from a fork), the diff is supplied below (as it won't show otherwise due to GitHub magic): diff --git a/omega/omega-transport/omega-transport-resttemplate/src/test/java/org/apache/servicecomb/saga/omega/transport/resttemplate/UniqueIdGeneratorTest.java b/omega/omega-context/src/test/java/org/apache/servicecomb/saga/omega/context/UniqueIdGeneratorTest.java similarity index 91% rename from omega/omega-transport/omega-transport-resttemplate/src/test/java/org/apache/servicecomb/saga/omega/transport/resttemplate/UniqueIdGeneratorTest.java rename to omega/omega-context/src/test/java/org/apache/servicecomb/saga/omega/context/UniqueIdGeneratorTest.java index 88ffac2e..bcedcfa2 100644 --- a/omega/omega-transport/omega-transport-resttemplate/src/test/java/org/apache/servicecomb/saga/omega/transport/resttemplate/UniqueIdGeneratorTest.java +++ b/omega/omega-context/src/test/java/org/apache/servicecomb/saga/omega/context/UniqueIdGeneratorTest.java @@ -6,17 +6,16 @@ * (the "License"); you may not use this file except in compliance with * the License.
