Developer tools: data script replayed on restart problem

[ggsurrel]

I have a spring boot application using liquibase and referencing a startup script using spring.datasource.data property. After migrating to spring boot 1.3.0 and testing developer tools automatic restart, I have a problem as my startup script is replayed at startup but previously loaded data is still there. Is there a way to avoid replaying startup script or to flush data on dev tools restart ?

How is your application supposed to run without devtools then? If it is being initialized on startup and it breaks that way, it should break if you stop the app and start it again (without Devtools). Can you give us a bit more details?

I have made a minimal project to reproduce the problem here: https://github.com/gsurrel-orange/boot-liquibase-dev-tools. On the first launch everything works fine but when the app is restarted by the dev tool module, there is a problem re-running the import script.

@gsurrel-orange Are you using an in-memory database? Is the root cause of this that a devtools restart doesn't clear the database where as a full restart does?

[ggsurrel]

@philwebb Exactly. This is why I can imagine 2 solutions: either clear the database like it's done on a full restart or avoid replaying the script.

I think clearing the database would be the better option, I'm actually quite surprised that doesn't happen by default. Thanks for reporting, will take a look.

tomcat-jdbc is on the classpath so while an embedded database is being used, Boot's running in non-embedded database mode. That means that the embedded database isn't closed when the application context closes.
