Can't Autowire @Repository annotated interface in Spring Boot

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 com.pharmacy.persistence.users.dao.UserEntityDao;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;


@SpringBootApplication
@EnableAutoConfiguration
@EnableJpaRepositories
@ComponentScan({"com.pharmacy.*"})
public class SpringBootRunner {

@Autowired
UserEntityDao userEntityDao;

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>{

}


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.
