JarCasting
Java library that helps you to create simple H2 Database snapshots
Add H2-Snaphosts to your project. For maven projects just add this dependency:
<dependency>
<groupId>com.afrunt.h2s</groupId>
<artifactId>h2-snapshots</artifactId>
<version>0.4</version>
</dependency>
Usage
Basically, you need to create the instance of the H2Snapshot class in order to create the snapshot of the current state.
import com.afrunt.h2s.H2Snapshot;
import com.sql.DataSource;
// ...
final H2Snapshot initialStateSnapshot = new H2Snapshot(dataSource);
// ...
To move database to the previous state, just invoke the apply(...) method like shown below
import com.afrunt.h2s.H2Snapshot;
import com.sql.DataSource;
// Remember the previous state
final H2Snapshot initialStateSnapshot = new H2Snapshot(dataSource);
// ...
// Apply previously created snapshot to db
initialStateSnapshot.apply(dataSource);
// ...
