Is your feature request related to a problem? Please describe.

Relate to issue #1424 #2539

User need to run sql manually to initial tables.

Is it possible to auto create those tables?

Describe the solution you'd like

Auto create tables when config service，admin service，portal startup.

Then user didn't need to run sql manually. That could be make operations and deployment more simpler.

Describe alternatives you've considered

Is hibernate support that? Maybe there are some configuration to support that.

Some problem need to consider

• Is it safe? i.e the influence of old data when services update.
• How user update their system if table auto create?

Spring Data Jpa can do that, but it is risky to me since the mysql account would have ddl permissions...
