For more testing deep-dive with Spring Boot using a real world application example (Java 14, Spring Boot, React, TypeScript, AWS, Keycloak, PostgreSQL), take a look at the Testing Spring Boot Applications Masterclass.
To enable Lombok in IntelliJ install Lombok plugin and enable annotation processing.
If you have a problem to see H2 console, try to find the string in logs like this jdbc:h2:mem:5e2dbb95-360b-4c51-b972-5179f0eb0950
the content is very helpful but the videos are just blurry i can not see clearly i just listen and code what i hear and it is bad. if you have hosted the videos somewhere else where they have quality please share the link.
Hey Tinyiko,
thanks for your feedback. Can you try to change the quality settings of the video? For me 1080p is fine.
In addition to this, I’m planning to re-record the whole course. This course was one of my first screencasts and hence I made a lot of mistakes 😀
Hope this helps,
Philip
Small addition as you used 2.2.0 M3 in this video: versions before 2.3 had default H2 database url as presented here (at 17:05)
"jdbc:h2:mem:testdb". However, that changed after v2.3 and following instructions in video will render error:"Database 'mem:testdb' not found, either pre-create it or allow remote database creation (not recommended in secure environments) [90149-200] 90149/90149"To avoid it, check the logs when you start your app and look for "H2 console available at '/h2-console'. Database available at 'jdbc:h2:mem:42420813-7df3-4a42-42df-7f531ff14242'", so you try to connect to the correct url.
Alternatively, you could explicitly specify url with:
spring.datasource.url=jdbc:h2:mem:testdbThanks a lot for this hint Vladi 🙂
How the mem:testdb name configured automatically. When i followed the tutorial, the name generated for h2 db is like “58a9b8d5-5dd0-4d74-a210-695e3e557729”. I am using 2.5.5 as springboot version
Maybe that’s something that changed with recent Spring Boot versions. Can you connect with the connection string presented in this lesson?
