Hi, you made a really good work in this video I was looking for videos like this using spring+VSCode I'll continue with your list. Greetings from Costa Rica!!

[@toufiqurrahman7025]

looks very good

[@mugiranezajohn5285]

well explained

[@letslearntogether7469]

This video was recorded before Spring boot 2.5. Spring boot 2.5 doesn't automatically add the POM.xml's Validation dependency. Please the following code in the project POM.xml inside dependencies. This will allow you to use @Id, @Size annotation inside the model object. : org.springframework.boot spring-boot-starter-validation

[@glennroland5359]

Hello, I've followed the tutuorial step by step. In the video you had any errors when you add dependencies in your pom.xml file but when I do so I got many errors (missing artifact). Can you help me ?

[@letslearntogether7469]

Can you please share your error? Add this code to POM.xml -> and let me know if it fixed the error. Spring Boot 2.5 doesn't automatically add the Validation's dependency: org.springframework.boot spring-boot-starter-validation
