Spring Boot not autowiring @Repository

Question

I'm trying to configure a datasource with Spring Boot but I'm getting org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'authenticationServiceImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.mycompany.myapp.repository.UserRepository com.mycompany.myapp.service.AuthenticationServiceImpl.userRepository; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.mycompany.myapp.repository.UserRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

These is my project structure:

Main Class:

package com.mycompany.myapp;
@ComponentScan(basePackageClasses = {com.mycompany.myapp.domain.user.User.class,
                                     com.mycompany.myapp.repository.UserRepository.class,
                                     com.mycompany.myapp.service.AuthenticationServiceImpl.class})
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

Domain Class:

package com.mycompany.myapp.domain.user
@Entity
public class User {

    @Id
    @GeneratedValue
    private long id;
    @Column(nullable = false)
    private String name;
    @Column(nullable = false)
    private String lastName;
    @Column(nullable = false)
    private String password;
    @Column(nullable = false)
    private String email;

    public User() {}

    public User(String email, String password){
        this.email = email;
        this.password = password;
    }
}

Repository:

package com.mycompany.myapp.repository;
public interface UserRepository extends CrudRepository<User, Long> {

    List<User> findByLastName(String lastName);
}

Controller

package com.mycompany.myapp.service;
@RestController
public class AuthenticationServiceImpl implements AuthenticationService {

    @Autowired
    private UserRepository userRepository;

    @RequestMapping("/add")
    public User add(){
        User user = new User();
        user.setName("Juan");
        user.setLastName("Sarpe");
        user.setEmail("email@gmail.com");
        userRepository.save(user);
        return user;
    }
}

application.properties

spring.datasource.url:jdbc:mysql://localhost:3306/mydb
spring.datasource.username=user
spring.datasource.password=pass
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.jpa.hibernate.ddl-auto=update

I guess my app is not detecting my @Repository annotation on UserRepository. As far as I know, Spring Boot will automatically set my class as @Repository because it is extending CrudRepository. What am I doing wrong? (Notice that my Application class is on top of packages hierarchy).

Looks OK to me. Is that all of the exception? Any nested exceptions? Check for another class with the same name(UserRepository). Do you have the right maven/gradle dependencies? Take a look at this guide: https://spring.io/guides/gs/accessing-data-jpa/ — Evgeni Dimitrov, Jun 03 '16 at 17:57
`ar.com.prokarma.tim.repository.UserRepository` is this a separate Class? — Jos, Jun 03 '16 at 17:59
Sorry, i have copied the code and exception and tried to run it. I have edited the description. I will add the exception before the stacktrace to the description. — Marcos, Jun 03 '16 at 18:17
You're missing @SpringBootApplication on the Application class. Please refer to the [Spring documentation](http://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-structuring-your-code.html) because package structure is very important. — kab, Jun 03 '16 at 20:54
Sorry, I´ve already tried setting `@SpringBootApplication` on my main class. But it won't identify my `@Repository`. That's why I tried setting it that way.. — Marcos, Jun 04 '16 at 18:17
Did you latter get to solve this and which of these solutions work or how did you you get around this — olyjosh, Oct 21 '17 at 10:42

In main class of spring boot you have to use this below annotation :

@SpringBootApplication
@ComponentScan(basePackages = "basepackage")
@EntityScan(basePackages ="basepackage")
@EnableAutoConfiguration
@EnableJpaRepositories(basePackages = "basepackage")

In Repository layer use below annotation :

import org.springframework.stereotype.Repository;

import org.springframework.transaction.annotation.Transactional;

@Transactional
@Repositor

If you have any service layer then use below annotation in the implementation class:

import org.springframework.stereotype.Service;

@Service

Have you tried @EnableJpaRepositories in your configuration ?

The standard way to configure is to create a base marker repository interface and provide that in the component scan.

public interface RepositoryPackage {
}

Keep the interface RepositoryPackage in the same package as UserRepository.

@ComponentScan(basePackageClasses= "RepositoryPackage.class")
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

I'm still getting the exception. It's not resolving the dependency. – Marcos Jun 03 '16 at 20:01
