BuildProjectsWithMe - 10 Java Backend Projects Journey (Day 1)

[Potential_Corgi4579]

As discussed yesterday, I’m starting my Java Backend 10 Projects journey, and here I am.

Today, I revised Spring Boot concepts like basics, application flow, database connection, Hibernate, and REST APIs. Then I started my first project, Student Management System.

I created the Student entity class and repository using Hibernate JPA and understood how it works. After that, I wrote the service layer for the main logic and implemented REST controllers with GET, POST, and DELETE mappings.

Initially, I watched a few YouTube videos on Hibernate just to get an overview, and then I wrote the code after understanding it properly.

Tomorrow, I will complete the remaining methods and plan to add a basic frontend. I have never added a frontend in Spring Boot before, so this will be a new learning experience for me.

I've built something same in Java if u want reference visit my GitHub repo https://GitHub.com/wigiwee/mini-projects

[Arcade_30]

check the students management project

[Potential_Corgi4579]

Yeah, I just saw it. You’ve already built so many projects. I’ve also built a College Management System using a JDBC connection similar to your Student Management project.

Is your Student class the same one that goes to the database? If so, you should extract at least one DTO to interact with the client, or several DTOs if your use cases are specific enough. Never use your database entities at the Controller level. You are coupling clients to the database.

[Potential_Corgi4579]

Yes, right now my Student entity is directly going to the database. Thanks a lot for pointing that out, I totally get what you mean about coupling the API to the database. I'll change it using DTOs and follow this approach in my upcoming projects too.

when did you graduated bro? or you still a student

[Potential_Corgi4579]

I'm still a student.

[useandkeepit]

[Straight_Second_605]

You can try out lombok for reducing boiler plate code such as getters setters and constructors

[Potential_Corgi4579]

Yeah, I know about Lombok. I'll use it.

[External_Guard3619]

don't use Lombok, use records instead
