findByName isn't work [Spring boot] - spring

Question

I have a problem with Spring boot.
I created Entity and Repository, but method findByName in Repository isn't work.
My url:
http://localhost:8080/student/search/findByName?name=Artem
In Google chrome: localhost not found, but search is mapped.
Entity:
#Getter #Setter
#Entity #Table(name = "Student")
public class Student extends BaseEntity{
private String name;
private String dateOfBirthDay;
private String sex;
private String phoneNumber;
}
BaseEntity:
#Getter
#Setter
#MappedSuperclass
public class BaseEntity {
#Id #GeneratedValue(strategy = GenerationType.SEQUENCE) #Column protected Long id;
My Repository:
#RepositoryRestResource(collectionResourceRel = "student", path = "student")
public interface StudentRepository extends PagingAndSortingRepository<Student, Long> {
Student findByName(#Param("name") String name);
}
Application:
#SpringBootApplication
#EnableTransactionManagement
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
Application.yaml:
spring:
application:
name: students
datasource:
driverClassName: org.postgresql.Driver
url: jdbc:postgresql://localhost:5432/students
username: postgres
password: postgres
jpa:
hibernate:
ddl-auto: update
server:
port: 8080

I recommend you to create a resource class, works like controller. Here a simple example:
#RestController
#RequestMapping("/yourPath") //students, whatever
public class StudentsResource {
#Autowired
private StudentRepository studentRepository;
//type media that you want to show (json, xml...in this case is JSON)
#RequestMapping(method = RequestMethod.GET, produces = { MediaType.APPLICATION_JSON_VALUE })
// <Student> is the entity, object
#RequestMapping(value = "/yourPath/{studentName}")
public ResponseEntity<Student> findByName(#pathVariable("studentName") String name) {
Student student = studentRepository.findByName(name);
if(student == null){
//handler your own exception here
}
//show the student as json object
return ResponseEntity.status(HttpStatus.OK).body(student);
}
Note: that's the resource class. But your problem is about localhost, so if you are using Spring Boot, see if your "application.properties" is correct. Here my example:
spring.datasource.url=jdbc:mysql://localhost:3306/yourDataBase
spring.datasource.username=yourUser
spring.datasource.password=yourPassword
spring.jpa.hibernate.ddl-auto=update //makes the spring create the database automatic!
