SpringBoot本地POST请求404问题排查求助

我是SpringBoot新手，跟着教程学习到「测试POST请求」环节（视频对应1:15:00），教程中请求成功返回200，但我操作步骤完全一致、代码也和教程一致，却收到404响应，日志显示来自nginx/1.23.0的404页面。

我用IntelliJ HTTP Client发送的POST请求：

###
POST http://localhost:8080/api/v1/student
Content-Type: application/json

{
  "name": "Whitney",
  "email": "wrob@apple.com",
  "dob": "1987-12-09"
}

我的目标是将Student对象存入数据库，以下是相关代码：

相关代码 #

StudentController类 #

@RestController
@RequestMapping(path = "api/v1/student")
public class StudentController {

    private final StudentService studentService;

    @Autowired
    public StudentController(StudentService studentService) {
        this.studentService = studentService;
    }

    @GetMapping
    public List<Student> getStudents(){
        return studentService.getStudents();
    }

    @PostMapping
    public void registerNewStudent(@RequestBody Student student){
        studentService.addNewStudent(student);
    }
}

StudentService类 #

@Service
public class StudentService {

    private final StudentRepository studentRepository;

    @Autowired
    public StudentService(StudentRepository studentRepository) {
        this.studentRepository = studentRepository;
    }

    public List<Student> getStudents() {
        return studentRepository.findAll();
    }

    public void addNewStudent(Student student) {
        Optional<Student> studentOptional = studentRepository.findStudentByEmail(student.getEmail());
        if (studentOptional.isPresent()){
            throw new IllegalStateException(("email taken"));
        }
        studentRepository.save(student);
    }
}

StudentConfig类 #

@Configuration
public class StudentConfig {

    @Bean
    CommandLineRunner commandLineRunner(StudentRepository repository){
        return args -> {
            Student david = new Student(
                    "David",
                    "drob@apple.com",
                    LocalDate.of(1985, NOVEMBER, 3)
            );

            Student alex = new Student(
                    "Alex",
                    "alex@apple.com",
                    LocalDate.of(1995, JANUARY, 1)
            );

            repository.saveAll(List.of(david, alex));
        };
    }
}

StudentRepository接口 #

@Repository
public interface StudentRepository extends JpaRepository<Student, Long> {

    @Query("SELECT s FROM Student s WHERE s.email = ?1")
    Optional<Student> findStudentByEmail(String email);
}

Student实体类 #

@Entity
@Table
public class Student {
    @Id
    @SequenceGenerator(
            name = "student_sequence",
            sequenceName = "student_sequence",
            allocationSize = 1
    )
    @GeneratedValue(
            strategy = GenerationType.SEQUENCE,
            generator = "student_sequence"
    )
    private Long id;
    private String name;
    private String email;
    private LocalDate dob;
    @Transient
    private Integer age;

    public Student(Long id, String name, String email, LocalDate dob) {
        this.id = id;
        this.name = name;
        this.email = email;
        this.dob = dob;
    }

    public Student(String name, String email, LocalDate dob) {
        this.name = name;
        this.email = email;
        this.dob = dob;
    }

    public Student() {

    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public LocalDate getDob() {
        return dob;
    }

    public void setDob(LocalDate dob) {
        this.dob = dob;
    }

    public Integer getAge() {

        return Period.between(this.dob, LocalDate.now()).getYears();
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    @Override
    public String toString() {
        return "Student{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", email='" + email + '\'' +
                ", dob=" + dob +
                ", age=" + age +
                '}';
    }
}
