spring.jpa.show-sql=true
Spring Application:
#SpringBootApplication(exclude = {UserDetailsServiceAutoConfiguration.class})
public class StudentsmanagerApplication {
public static void main(String[] args) {
SpringApplication.run(StudentsmanagerApplication.class, args);
}
Controller class:
#RestController
#RequestMapping("/student")
public class StudentController {
private StudentService studentService;
#GetMapping
public ResponseEntity<List<Student>> getAllStudents() {
List<Student> students = studentService.findAllStudent();
return new ResponseEntity<>(students, HttpStatus.OK);
}
#GetMapping("find/{id}")
public ResponseEntity<Student> getAllStudentsById(#PathVariable Long id) {
Student student = studentService.findStudentById(id);
return new ResponseEntity<>(student, HttpStatus.OK);
}
#PostMapping
public ResponseEntity<Student> addEmployee(#RequestBody Student student) {
Student newStudent = studentService.addStudent(student);
return new ResponseEntity<>(newStudent, HttpStatus.CREATED);
}
#PutMapping("/{id}")
public ResponseEntity<Student> updateStudent(#PathVariable Long id, #RequestBody Student
student) {
Student updatedStudent = studentService.updateStudent(id, student);
return new ResponseEntity<>(updatedStudent, HttpStatus.UPGRADE_REQUIRED);
}
#DeleteMapping("/{id}")
public ResponseEntity<?> deleteStudent(#PathVariable Long id) {
studentService.deleteStudent(id);
return new ResponseEntity<>(HttpStatus.OK);
}

#Service
public class StudentService {
private StudentRepository studentRepository;
public Student addStudent(Student student) {
student.setStudentCode(UUID.randomUUID().toString());
return studentRepository.save(student);
}
public List<Student> findAllStudent() {
return studentRepository.findAll();
}
public Student updateStudent(Long id, Student student) {
Student studentById = studentRepository
.findById(id).orElseThrow(() -> new StudentNotFoundException("Student by id
" + " doesn't Exist"));
studentById.setName(student.getName());
studentById.setLastName(student.getLastName());
studentById.setEmail(student.getEmail());
studentById.setPhone(student.getPhone());
return studentRepository.save(studentById);
}
public Student findStudentById(Long id) {
return studentRepository
.findById(id).orElseThrow(() -> new StudentNotFoundException("Student
doesn't exist "));
}
public void deleteStudent(Long id) {
studentRepository.deleteById(id);
}
