and my JPA Repository
package com.upload.FileUpload.service;
import com.upload.FileUpload.entity.FileEntries;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
#Repository
public interface UploadRepository extends JpaRepository<FileEntries,Integer> {
}
My Service Impl class is
package com.upload.FileUpload.service;
import lombok.AllArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Service;
import javax.transaction.Transactional;
#Service
#AllArgsConstructor
#Slf4j
#Transactional
public class UploadServiceImpl implements UploadService {
private UploadRepository uploadRepository;
}
My Mainapplication.class
package com.upload.FileUpload;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
#SpringBootApplication(exclude={DataSourceAutoConfiguration.class})
public class FileUploadApplication {
public static void main(String[] args) {
SpringApplication.run(FileUploadApplication.class, args);
}
My application.properties
spring.datasource.driverClassName=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/postgres
spring.datasource.username=postgres
spring.datasource.password=root
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQL95Dialect
spring.jpa.generate-ddl=true
spring.jpa.show-sql=true
spring.datasource.sql-script-encoding=UTF-8
I am getting the below error
APPLICATION FAILED TO START
***************************
Description:
Parameter 0 of constructor in com.upload.FileUpload.service.UploadServiceImpl required a bean of
type 'com.upload.FileUpload.service.UploadRepository' that could not
be found.
Action:
Consider defining a bean of type 'com.upload.FileUpload.service.UploadRepository' in your
configuration.
Can someone tell me what is the issue here

Answer 1

you have to add #Autowired Annotation on your UploadRepository Declaration
package com.upload.FileUpload.service;
import lombok.AllArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Service;
import javax.transaction.Transactional;
#Service
#AllArgsConstructor
#Slf4j
#Transactional
public class UploadServiceImpl implements UploadService {
#Autowired
private UploadRepository uploadRepository;
}
