Can't Autowire @Repository annotated interface in Spring Boot

Question

I'm developing a spring boot application and I'm running into an issue here. I'm trying to inject a @Repository annotated interface and it doesn't seem to work at all. I'm getting this error

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'springBootRunner': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.pharmacy.persistence.users.dao.UserEntityDao com.pharmacy.config.SpringBootRunner.userEntityDao; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.pharmacy.persistence.users.dao.UserEntityDao] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Here is my code:

Main application class:

package com.pharmacy.config;  import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.annotation.ComponentScan;   @SpringBootApplication @ComponentScan("org.pharmacy") public class SpringBootRunner {       public static void main(String[] args) {         SpringApplication.run(SpringBootRunner.class, args);     } } 

Entity class:

package com.pharmacy.persistence.users;  import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id;    @Entity public class UserEntity {      @Id     @GeneratedValue     private Long id;     @Column     private String name;  } 

Repository interface:

package com.pharmacy.persistence.users.dao;  import com.pharmacy.persistence.users.UserEntity; import org.springframework.data.repository.CrudRepository; import org.springframework.stereotype.Repository;   @Repository public interface UserEntityDao extends CrudRepository<UserEntity,Long>{  } 

Controller:

package com.pharmacy.controllers;  import com.pharmacy.persistence.users.UserEntity; import com.pharmacy.persistence.users.dao.UserEntityDao; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController;   @RestController public class HomeController {       @Autowired     UserEntityDao userEntityDao;      @RequestMapping(value = "/")     public String hello() {         userEntityDao.save(new UserEntity("ac"));         return "Test";      } } 

build.gradle

buildscript {     ext {         springBootVersion = '1.2.2.RELEASE'     }     repositories {         mavenCentral()     }     dependencies {         classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")     } }  apply plugin: 'java' apply plugin: 'idea' apply plugin: 'spring-boot' mainClassName = "com.pharmacy.config.SpringBootRunner" jar {     baseName = 'demo'     version = '0.0.1-SNAPSHOT' }   repositories {     mavenCentral() }   dependencies {     compile("org.springframework.boot:spring-boot-starter-data-jpa")     compile("org.springframework.boot:spring-boot-starter-web")     compile("org.springframework.boot:spring-boot-starter-ws")     compile("postgresql:postgresql:9.0-801.jdbc4")      testCompile("org.springframework.boot:spring-boot-starter-test") } 

application.properties:

spring.view.prefix: / spring.view.suffix: .html  spring.jpa.database=POSTGRESQL spring.jpa.show-sql=false spring.jpa.hibernate.ddl-auto=update   spring.datasource.driverClassName=org.postgresql.Driver spring.datasource.url=jdbc:postgresql://localhost:5432/postgres spring.datasource.username=postgres spring.datasource.password=abc123 

I even compared my code with Accessing data jpa, and I'm running out of ideas what's wrong with this code. Any help appreciated. Thanks in advance.

EDITED: I changed my code as suggested to look like above, and I'm not getting that error when I'm injecting my @Repository interface into another component. However, I have a problem now - my component cannot be retrieved (I used debugging). What I'm doing wrong so spring cannot find my component?

Answer 1

When the repository package is different to @SpringBootApplication/@EnableAutoConfiguration, base package of @EnableJpaRepositories is required to be defined explicitly.

Try to add @EnableJpaRepositories("com.pharmacy.persistence.users.dao") to SpringBootRunner
