</project>

my properties file:

spring.datasource.url=jdbc:postgresql://localhost:5432/database
spring.datasource.username=user
spring.datasource.password=pass
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
spring.jpa.hibernate.ddl-auto = update

my spring boot application class:

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@SpringBootApplication
@EnableJpaRepositories
public class ExampleApplication {

    public static void main(String[] args) {
        SpringApplication.run(ExampleApplication.class, args);
    }

}

controller class:

import com.example.example.entities.Thing;
import com.example.example.repositories.ThingRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class CreateThingController {

    private ThingRepository thingRepository;

    @Autowired
    public CreateThingController(ThingRepository thingRepository){
        this.thingRepository = thingRepository;
    }

    @PostMapping("/things")
    public void createThing(@RequestBody Thing thing) {
        this.thingRepository.save(thing);
    }
}

My entity class:

import org.springframework.data.annotation.Id;

import javax.persistence.*;

@Entity
public class Thing {

    @Id
    @Column(name = "id", nullable = false, updatable = false)
    private String id;

    @Column(name = "name", nullable = false, updatable = false)
    private String name;

    public Thing(
            String id,
            String name
    ) {
        this.id = id;
        this.name = name;
    }

    public String getId() {
        return id;
    }

    public String getName() {
        return name;
    }
}

and this is my repository interface:

import com.example.example.entities.Thing;
import org.springframework.stereotype.Repository;
import org.springframework.data.jpa.repository.JpaRepository;


@Repository
public interface ThingRepository extends JpaRepository<Thing, String> 
{

}

The error is this:

Parameter 0 of constructor in com.example.example.controllers.CreateThingController required a bean named 'entityManagerFactory' that could not be found.

i trying to fix the error following other response and tutorials, but i fail. What could be the problem here? I need to configure something else?
