I am new to Spring Boot and created a basic Restful CRUD API project: OnlineNotes using Spring Boot-JPA-MySQL(Maven-based).
I am trying to run the project in IntelliJ and facing below error:
Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'noteController': Unsatisfied dependency expressed through field 'noteRepository': Error creating bean with name 'noteRepository' defined in com.example.notesApp.repository.NoteRepository defined in @EnableJpaRepositories declared on JpaRepositoriesRegistrar.EnableJpaRepositoriesConfiguration: Not a managed type: class com.example.notesApp.model.Notes

I checked other answers in stackOverFlow and implemented the solution, still facing the issue.
I have created project structure from Spring Initialzr with below structure:
notesApp
├── src
│ ├── main
│ │ ├── java
│ │ │ ├── com
│ │ │ │ ├── example
│ │ │ │ │ ├── notesApp
│ │ │ │ │ │ ├── controller
│ │ │ │ │ │ │ ├── NoteController.java
│ │ │ │ │ │ ├── model
│ │ │ │ │ │ │ ├── Notes.java
│ │ │ │ │ │ ├── repository
│ │ │ │ │ │ │ ├── NoteRepository.java
│ │ │ │ │ │ ├── NotesAppApplication.java
Below is the list of project files created:
- Model class: Notes.java
@Entity//Marks class as entity class for component scan
@Table (name = "notes")//Creates table named notes in DB
@EntityListeners(AuditingEntityListener.class)
@JsonIgnoreProperties(value = {"createdAt","updatedAt"}, allowGetters = true)//Makes variables un-editable for users by ignoring values if client provides in put/update service call
public class Notes implements Serializable {
@Id//Defines upcoming var as primary key in table
@GeneratedValue (strategy = GenerationType.IDENTITY)//Allows auto-increment for primary key
private long id;
@NotBlank
private String title;
@NotBlank
private String content;
@Column(nullable = false, updatable = false)//Defines column properties in DB
@Temporal(TemporalType.TIMESTAMP)//Converts dates in appropriate formats in DB
@CreatedDate
private Date createdAt;
@Column(nullable = false, updatable = false)
@Temporal(TemporalType.TIMESTAMP)
@LastModifiedDate
private Date updatedAt;
- Repository class: NoteRepository.java
package com.example.notesApp.repository;
import com.example.notesApp.model.Notes;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
@Repository//Asks Spring to bootstrap the repository during component scan
public interface NoteRepository extends JpaRepository<Notes, Long> {
}
3.Controller : NoteController.java
//Controller to create, retrieve, Update, delete a note
@RestController //Combination of @Controller and @ResponseBody
//@Controller defines this class is Controller to be bootstrapped while component scan
//@ResponseBody indicates the return value of method will be the response body
@RequestMapping(value = "/api")
//@RequestMapping defines the pattern of request URL
public class NoteController {
@Autowired
NoteRepository noteRepository;
//Get all notes
@GetMapping(value = "/notes")//@GetMapping handles the HTTP Get request and maps GET /notes/ URL to getAllNotes method
public List<Notes> getAllNotes(){
return noteRepository.findAll();
}
//Get a single note
@GetMapping(value = "notes/{id}") //@GetMapping handles the HTTP Get request and maps GET /notes/{id} URL to getNotesById method
public Notes getNotesById(@PathVariable(value = "id") long id){
return noteRepository.findById(id).orElseThrow(()->new ResourceNotFoundException("Note","Id",id));
}
//Create a note
@PostMapping (value = "/notes")//@PostMapping handles the HTTP POST request and maps POST /notes/ URL to createNote method
public Notes createNote (@Valid @RequestBody Notes notes){
//@Valid makes sure Request Body is valid as Title and Content of request is assigned to @NotNull annotation
//@RequestBody binds request with method parameters
return noteRepository.save(notes);
}
//Update a note
@PutMapping(value = "notes/{id}")//@PutMapping handles the PUT request and maps PUT /notes/{Id} URl to updateNote method
public Notes updateNote(@PathVariable(value = "id")long noteId, Notes UpdatedNote){
Notes note = noteRepository.findById(noteId).orElseThrow(()->new ResourceNotFoundException("Note","Id",noteId));
//Only Title and content are eligible for update
note.setTitle(UpdatedNote.getTitle());
note.setContent(UpdatedNote.getContent());
return noteRepository.save(note);
}
//Delete a note
@DeleteMapping(value = "notes/{id}")//@DeleteMapping handles DELETE request and maps DELETE notes/{id} to deleteNote method
public void deleteNote(@PathVariable(value = "id")long id){
Notes note = noteRepository.findById(id).orElseThrow(()-> new ResourceNotFoundException("Note","Id",id));

}
}
Please help in resolving the error.
can you please add the error message of the stacktrace following the “Caused by” that’s visible in your screenshot to your question?
@cyberbrain : Updated the complete error stack trace
Let me guess you are “following” a tutorial and decided to upgrade to the newest available library versions. Then you got compilation errors and decided to add a dependency to fix the compilation errors. In your entity replace the
javax.persistenceimports withjakarta.persistenceand remove the additional dependencies you have.Hello @M.Deinum, thanks a lot, it worked. Also, you guessed everything right!! 🙂
