The problem was on the jdbc URL which was wrong.

I had jdbc:mysql://myserver.com instead of jdbc:mysql:aurora://myserver.com

example.com is an actual domain, though according to this rfc it is reserved for example use.

If you lookup the DNS record for example.com you can see that it resolves to a real IP address, and not to your server:

The underlying issue has nothing to do with Spring Boot/Hibernate or your test setup.

The SQL statement SELECT COUNT(*) FROM Person returns a single row with a single column that contains the number of counted rows:

You can use ApplicationContext#getBeansWithAnnotation. It will not only take classes with @Configuration annotation but also classes annotated with annotations meta-annotated with @Configuration, like @SpringBootApplication:

H2 dropped support for trailing commas in 1.4.200. Spring Boot upgraded to H2 1.4.200 in 2.1.10 and 2.2.1 and, at the time of writing, it has been the default version of H2 in all Spring Boot releases since then. When you upgrade to Spring Boot 2.3.3 you are also upgrading to H2 1.4.200 so the trailing commas in your migration are no longer support.

If you're curious where these versions are coming from, they're inherited via spring-boot-starter-parent which uses spring-boot-dependencies as its parent. spring-boot-dependencies contains dependency management for numerous Spring projects and third-party dependencies, including H2. The default versions for any given version of Spring Boot are included in the reference documentation:

• Dependency versions in 2.1.1.RELEASE
• Dependency versions in 2.3.3.RELEASE

This is a bug in Log4j2.

I set up a quick project in IntelliJ, added the log4j2 2.14 api and core JARs and a database driver JAR and ran your code, and I was able to reproduce the incorrectly-formatted INSERT statement in your error message.

I used IntelliJ to download the log4j2 source JAR and attach it, and stepped through the code that put together the INSERT statement. The method that adds the column names to the SQL string is called appendColumnNames and is in the class JdbcDatabaseManager. It contains the following code, which I've abbreviated for clarity:

So, for future reference: The problem was not anything gradle/liquibase specific. It was simply the fact, that I created the directories db/changelog in one step in Intellij, which created one dir db.changelog instead of /changelog being the child of db. After splitting that up in two separate steps, everything is working out fine!

It seems you are using JAX-RS and not Spring MVC. There is no JAX-RS - Sentry integration working out of the box.

To forward exceptions to Sentry you can also use sentry-logback integration. You can configure Logback to forward any logger error to Sentry. The drawback of not having Spring integration there too is that errors are not decorated with contextual information from the HTTP request.

Just put the code (starting with the try) in a @GetMapping method.
