H2-console in r2dbc-h2 driver

Question

I am using R2DBC-H2 driver, and my UR.L is spring.r2dbc.url=r2dbc:h2:mem:///customer

Using this configuration, SpringBoot starts fine, however, I can not access the h2-console.

Does anybody know why, and how I can fix it?

Answer 1

If I understand the source code of H2ConsoleAutoConfiguration correctly, the h2 console auto configuration from spring boot does not work in a reactive environment.

...
@ConditionalOnWebApplication(type = Type.SERVLET)
...
public class H2ConsoleAutoConfiguration {

You can confirm this by yourself by changing the type of your web application to SERVLET (for example, by adding spring-boot-starter-web as a dependency) which will activate the route to the h2 console (if enabled in the application properties). The h2-console route endpoint will start working again.

As the whole code seems very servlet-specific, I don't know how to properly fix this problem.
