🔍 Review Checklist – JPA and Hibernate
This checklist is used during the weekly review session to evaluate code quality, understanding, and implementation.
🎯 Review Objective
Ensure the learner:
- Understands JPA concepts clearly
- Writes clean and maintainable code
- Implements correct entity relationships
- Follows backend best practices
🧱 1. Entity Design Review
- ☐
@Entityand@Tableused correctly - ☐ Primary key properly defined (
@Id,@GeneratedValue) - ☐ Field names are meaningful and consistent
- ☐ No unnecessary fields
- ☐ Proper encapsulation (getters/setters)
🔗 2. Relationship Mapping Review
- ☐ Correct use of
@OneToManyand@ManyToOne - ☐
mappedByused correctly - ☐ Foreign key created in database
- ☐ Parent-child relationship properly maintained
- ☐ Cascade type used appropriately
- ☐ FetchType is set to LAZY where needed
⚙️ 3. Repository Layer Review
- ☐ Repository extends
JpaRepository - ☐ No unnecessary custom queries
- ☐ Method names follow Spring Data conventions
🧩 4. Service Layer Review
- ☐ Business logic is in service layer (not controller)
- ☐ Proper handling of null / missing data
- ☐ Exceptions handled correctly
- ☐ Relationships are set properly (e.g.,
course.setStudent(student)) - ☐ Code is modular and readable
🌐 5. Controller Layer Review
- ☐ REST endpoints are correctly defined
- ☐ Proper use of
@RequestBodyand@PathVariable - ☐ No business logic inside controller
- ☐ Clear and meaningful API structure
🧪 6. Validation Review
- ☐ Input validation implemented (
@NotBlank,@Email) - ☐ Invalid data is handled properly
- ☐ Error messages are meaningful
🧹 7. Code Quality Review
- ☐ Code is clean and readable
- ☐ Naming conventions followed
- ☐ No duplicate code
- ☐ Methods are not too long
- ☐ Proper formatting
⚠️ 8. Common Pitfalls Check
- ☐ No unnecessary EAGER fetching
- ☐ No missing
mappedBy - ☐ No LazyInitializationException
- ☐ No direct repository calls from controller
- ☐ No infinite recursion in relationships
🧪 9. Testing & Functionality
- ☐ APIs tested using Postman
- ☐ CRUD operations working
- ☐ Relationships working correctly
- ☐ Data persists in database
- ☐ Edge cases tested
🧠 10. Concept Understanding (Ask During Review)
Ask the learner:
- What is ORM?
- Difference between JPA and Hibernate?
- Why use LAZY fetching?
- What is
mappedBy? - What happens if relationship is not set properly?
