Error Creating bean with name 'transactionController'

Question

I’m starting to learn Spring and I’m getting this error, I’ve done several searches on the internet but so far I don’t understand what is causing the problem:

    org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'transactionController' defined in file [/Users/seuvito/Projetos/meubolso/target/classes/com/financas/meubolso/transaction/TransactionController.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'transactionServiceImpl': Unsatisfied dependency expressed through field 'transactionRepoCustom'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionRepoCustom' defined in com.financas.meubolso.transaction.TransactionRepoCustom defined in @EnableJpaRepositories declared on JpaRepositoriesRegistrar.EnableJpaRepositoriesConfiguration: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Failed to create query for method public abstract void com.financas.meubolso.transaction.TransactionRepoCustom.deleteTransactionId(java.lang.String)! No property deleteTransactionId found for type Transaction!

Class:

package com.financas.meubolso.transaction;

import lombok.Getter;
import lombok.Setter;
import org.hibernate.annotations.GenericGenerator;

import javax.persistence.*;

@Getter
@Setter
@Entity
@Table
public class Transaction {

    @Id()
    @Column(name = "id")
    @GeneratedValue(generator = "uuid")
    @GenericGenerator(name = "uuid", strategy = "uuid2")
    private String id;

    @Column(name = "title")
    private String title;

    @Column(name = "amount")
    private Double amount;

    @Column(name = "category")
    private String category;

    @Column(name = "type")
    private String type;

    public Transaction() {
    }

    public Transaction(String title, Double amount, String category, String type) {
        this.title = title;
        this.amount = amount;
        this.category = category;
        this.type = type;
    }

    public Transaction(String id, String title, Double amount, String category, String type) {
        this.id = id;
        this.title = title;
        this.amount = amount;
        this.category = category;
        this.type = type;
    }

    @Override
    public String toString() {
        return "Transaction{" +
                "id='" + id + '\'' +
                ", title='" + title + '\'' +
                ", amount=" + amount +
                ", category='" + category + '\'' +
                ", type='" + type + '\'' +
                '}';
    }
}

Contoller:

package com.financas.meubolso.transaction;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
@RequestMapping(path = "api/v1/transactions")
public class TransactionController {
    private TransactionServiceCustom transactionServiceCustom;

    @Autowired
    public void setTransactionService(TransactionServiceCustom transactionServiceCustom) {
        this.transactionServiceCustom = transactionServiceCustom;
    }

    @Autowired
    public TransactionController(TransactionServiceCustom transactionServiceCustom) {
        this.transactionServiceCustom = transactionServiceCustom;
    }

    @RequestMapping(value = "transaction", method = RequestMethod.GET)
    public List<Transaction> ShowAllTransaction(TransactionServiceCustom transactionServiceCustom) {
        return transactionServiceCustom.getTransaction();
    }
}

Service:

package com.financas.meubolso.transaction;

import org.springframework.stereotype.Service;

import java.util.List;

@Service
public interface TransactionServiceCustom {
    void addTransaction(Transaction transaction);
    List<Transaction> getTransaction();
}

Service Impl

package com.financas.meubolso.transaction;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import java.util.List;

@Service
public class TransactionServiceImpl implements TransactionServiceCustom {

    @Autowired
    private TransactionRepoCustom transactionRepoCustom;

    @Transactional
    public void addTransaction(Transaction transaction) {
        transactionRepoCustom.saveAndFlush(transaction);
    }

    @Transactional
    public List<Transaction> getTransaction() {
        return List.of(
                new Transaction(
                        "id",
                        "aluguel",
                        10.00,
                        "habitacao",
                        "despesa"

                )
        );
    }

}

Repository

package com.financas.meubolso.transaction;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

import java.util.Optional;

@Repository
public interface TransactionRepoCustom extends JpaRepository<Transaction, String> {

    void deleteTransactionId(String id);
    Optional<Transaction> findTransactionById(String id);
}

I am very grateful if someone can help me what is wrong in my code.

Answer 1

In the TransactionRepoCustom, delete the method:

void deleteTransactionId(String id);

Like TransactionRepoCustom is the daughter of JpaRepository, she inherits deleteById(id). So, when you need to delete via id, you can use:

instanceRepository.deleteById(id)

Another thing. You can take @Service of the interface TransactionServiceCustom. Just leave it in the implementation class TransactionServiceImpl.

If you make new mistakes add the question to try to help.
