I haven't even finished watching it and I can already say: Beautiful video! I've seen others (channels) very good ones, but this one is sensational. It explains exactly what is happening and why. This is giving me unprecedented autonomy, which I would take a good amount of practice and reading time to achieve. Thank you!🤩
Hey Dan, Thanks for your really helpful videos. It would be really nice if you make a video on how to configure databases like Oracle, MySQL or MongoDB etc any one will work. Thanks
Thank you for the suggestion. I am trying something new to keep track of content suggestions like this one and I have added it to a repo. github.com/danvega/office-hours/discussions/24
Hi Dan, As I can see in SB configs EmbeddedDatabase implements shutdown method (which sends SHUTDOWN command to the DB) and SB registres that as destroy method when no Hikari is used. But if we use Hikari+H2 Hikari knows nothing about whether it is an Embedded datasource or not. If we use memory-based H2 I suppose it is not a problem. But what about file-based H2? What do you think is it safe to use file-based H2 with Hikari? Will it close the file properly?
Hi, thank you for this tutorial!! i tried to follow when i do new Book(null, "str") i have error that id connot be null if i pass an id i have this error : Caused by: java.lang.IllegalArgumentException: After saving the identifier must not be null
can we use a string as the id of h2 table ? i have this error when i try to insert on the table with the id is a string column : Caused by: java.lang.IllegalArgumentException: After saving the identifier must not be null
Why this h2 console configuraton is not working with mvcMatchers? MvcMatcher as I understand is better version of antMatcher because it matches not only for example /demo but also /demo/ and /demo.html In My project mvcMatchers("/h2-console/**) is not working but if i have the antMatchers("/h2-console/**) as you, everything is fine, but why?
Hi Dan - I'm using Spring Boot 3 (Spring Security 6) and I can't access the H2 console. With Spring Security 6 there is no antMatchers or mvcMatchers only requestMatchers which don't allow us the access the console - I have this line auth.requestMatchers("/h2-console/**").permitAll(). Is there a workaround to allow access?
love your tutorials but cannot follow as you are using white theme because its difficult for me to work at the white screen, i request you to use dark theme if possible
I get if dark theme is your personal preference (It's mine too) but I am not sure I understand why you can't follow along? Light themes are just better for tutorials and presentations and are easier for people to follow along with.
I have no idea why do you have only 17K subs ... are people blind! I'm glad I found your channel.
Sacrified some mins to see this video and saved a lot of debugging hours. Thanks for the content.

God... I haven't seen anything better, sir. Thank you for sharing your expertise.
Amazing video❤ was struggling for two days then found this master piece.
No doubts! The greatest video about this topic. Simple and straight to the point. 🙂 Congratulations and thanks for sharing it.
Thank you for this video. So much valuable information packed in 1 video. Concisely presented. 💯
oh man, thank you im intern and im studying for this on 4 days. finally i do that thanks to you
Thanks for sharing such crisps videos.
Wow, this clears my doubts why you configure the data source that way in your previous tutorials. ❤
Learned lots of hows and WHYs along the journey, esp. the spring security part. 😘
I must say thank you for all your effort Dan. This is a very clear and effective video
I'm glad you found it useful.
Good work, i'm new to spring & this is better than paid courses.
This made my day! Thank you so much 🤩
Thanks, this was really clear and helpful for an exercise im doing :)
Thanks for the video, it's a really helpful tutorial
your work is professional !

is it possible to use hikari with an in memory database like h2 just to test the pooling?
Hi Dan,
As I can see in SB configs EmbeddedDatabase implements shutdown method (which sends SHUTDOWN command to the DB) and SB registres that as destroy method when no Hikari is used.
But if we use Hikari+H2 Hikari knows nothing about whether it is an Embedded datasource or not.
If we use memory-based H2 I suppose it is not a problem.
But what about file-based H2?
What do you think is it safe to use file-based H2 with Hikari? Will it close the file properly?
love the background
how does spring repository know about the presence of H2 table
Hi, thank you for this tutorial!!
i tried to follow when i do new Book(null, "str") i have error that id connot be null
if i pass an id i have this error : Caused by: java.lang.IllegalArgumentException: After saving the identifier must not be null
This sounds like a schema issue. Are you auto generating an id in your schema?
@@DanVega this my schema :
CREATE TABLE IF NOT EXISTS client (
id INTEGER AUTO_INCREMENT,
info BLOB
);
and this is my client record : public record Client(@Id Integer id, String info) { }
@@DanVega Thank you, i figured it out, the @Id was not imported from the right package
can we use a string as the id of h2 table ?
i have this error when i try to insert on the table with the id is a string column : Caused by: java.lang.IllegalArgumentException: After saving the identifier must not be null
Why this h2 console configuraton is not working with mvcMatchers?
MvcMatcher as I understand is better version of antMatcher because it matches not only for example /demo but also /demo/ and /demo.html
In My project
mvcMatchers("/h2-console/**) is not working but if i have the antMatchers("/h2-console/**) as you, everything is fine, but why?
i love this video!
How I can create a repository using sql raw in H2 DB?
Hi Dan - I'm using Spring Boot 3 (Spring Security 6) and I can't access the H2 console. With Spring Security 6 there is no antMatchers or mvcMatchers only requestMatchers which don't allow us the access the console - I have this line auth.requestMatchers("/h2-console/**").permitAll(). Is there a workaround to allow access?
I am facing the same issue, Did you get any solution?
the same
👏👏👏

@@DanVega i got a eye diesease because of which i can't see properly on white screen but anyways thanks for the reply
Wtf is the record class?
Record type is new to Java which is available in Java 16+
