jhipster run embedded jar with prod profile - issue with liquibase

问题:

I have packaged my app with : mvn -Pprod package

Then I ran

java -jar myapp-0.0.1-SNAPSHOT.war 

it works fine. But if I run :

java -jar myapp-0.0.1-SNAPSHOT.war --spring.profiles.active=prod 

I am getting this error:

I don't understand why prod profile causes this issue. If someone knows what's wrong here

Thank you.

Reading all the way to the bottom of the stack trace, I see that the root cause is a liquibase checksum validation failure. I'm not sure how familiar you are with liquibase, but it is a tool that is embedded inside jhipster that is used to manage database schema changes as your objects change. What liquibase does is use an XML format to describe the database schema as a series of 'changesets'. When liquibase deploys a changeset (i.e. a changeset that says 'changeset with id "CreateTableFoo" is "create table foo with columns bar baz etc") is that it actually creates the table, and then it also adds a row to a table called 'liquibasechangelog' that records that the changeset "CreateTableFoo" was successfully applied at such and such a time, and the checksum of that changeset was some value. Now, if you come along and change the changeset xml file so that the changeset "CreateTableFoo" instead creates a table with a different name or different columns, then the checksum calculated for that changeset also changes, so when you try to update the schema liquibase says "Wait! Something wrong!"

So that is what is happening here.

Error creating bean with name 'liquibase' defined in class path resource [com/myapp/config/DatabaseConfiguration.class]: Invocation of init method failed; nested exception is liquibase.exception.ValidationFailedException: Validation Failed: 1 change sets check sum classpath:config/liquibase/changelog/00000000000000_initial_schema.xml::00000000000001::jhipster is now: 7:788e6cd59e4764c45e1b83437356e748

What this indicates is that the prod database already has had a liquibase update run on it to populate the schema, but that the changeset has changed since that initial deploy. I am not familiar with how jhipster uses liquibase, so you would need to look at the file classpath:config/liquibase/changelog/00000000000000_initial_schema.xml to see what database schema it is trying to set up, compare that to the schema that is actually in place in production.

Now that things are out of sync, you'll have to figure out a way to get them back in sync, which is more complicated than can be answered here and depends greatly on what the differences between the changelog and the production schema are.
