Dubbo2.7 has very little information other than the official documents. Since the dubbo version in the project will be upgraded to the latest version later, so use a simple test to test it first (the test is this https ://www.cnblogs.com/sheng-yang/p/11307199.html).
The new features of 2.7 (metadata center, configuration center…) are not used in the test.
The main changes are:
1, pom file
p>
com.alibabaChange toorg.apache.dubbo
2. xml file
Use of the new version:

Here we must pay attention to the version matching problem. I used the curator-recipes version before If it is too high and it makes a mistake, it will be no problem to change to a low version.
Turn on zookeeper, run ServiceTest, start the service, and view it in dubbo-ops

Description:
If you are running on a virtual machine, you can write an execution script, package the project, copy it to the virtual machine, decompress it, and run the script file
Building a dubbo environment on Linux, this article is quite comprehensive https://www.cnblogs.com/sunnyplab/p/9546454.html (not for the latest version, but most of them can be used for reference) )
