Description:
Field userRepository in com.rst.boot.services.impl.UserServiceImpl required a bean named 'entityManagerFactory' that could not be found.
Action:
Consider defining a bean named 'entityManagerFactory' in your configuration.
This is my service class:
@Service
public class UserServiceImpl implements UserServices {
@Autowired
private UserRepository userRepository;
@Override
public List<UserDTO> findAllUsers() {
List<UserDTO> allusers= userRepository.findAll();
return allusers;
}
@Override
public String saveUser(UserDTO userdata) {
userRepository.save(userdata);
return "Data saved";
}
}

First, in your bootstrap class make sure you have the @EnableAutoConfiguration annotation. If you have @SpringBootApplication, should be enough, since the latter is annotated with the first.
@SpringBootApplication
public class MyApp {
public static void main(String[] args) {
SpringApplication.run(MyApp.class, args);
}
}
Second, make sure that UserRepository extends JpaRepository or CrudRepository:
public interface UserRepository extends JpaRepository<User, Long> {}
Last, check that you have the correct dependency in your maven or gradle configuration. E.g.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
