seeker_id INT,
opening_id INT,
application_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
status VARCHAR(20) DEFAULT 'PENDING',
FOREIGN KEY (seeker_id) REFERENCES job_seekers(seeker_id),
FOREIGN KEY (opening_id) REFERENCES job_openings(opening_id)
);

Describe the design of the front-end interface of the mini program, including pages for job information browsing, resume submission, recruitment posting, etc.
4. Implementation
4.1 Development environment
List the tools and technologies used in system development, including IDE, database, etc.
4.2 Backend implementation
Provide key code snippets to illustrate how to use the SSM framework to implement the core functions of the system.
Backend module implements part of the code:
import java.io.Serializable;
public class Student implements Serializable {
private Long studentId;
private String username;
private String password;
private String name;
private String major;
private String contactNumber;
private String email;
private String resume;
// Getters and setters
}
import java.util.List;
public interface StudentService {
List<Student> getAllStudents();
Student getStudentById(Long studentId);
void addStudent(Student student);
void updateStudent(Student student);
void deleteStudent(Long studentId);
}
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import java.util.List;
@RestController
@RequestMapping("/api/students")
public class StudentController {
@Autowired
private StudentService studentService;
@GetMapping
public List<Student> getAllStudents() {
return studentService.getAllStudents();
}
@GetMapping("/{studentId}")
public Student getStudentById(@PathVariable Long studentId) {
return studentService.getStudentById(studentId);
}
@PostMapping
public void addStudent(@RequestBody Student student) {
studentService.addStudent(student);
}
@PutMapping
public void updateStudent(@RequestBody Student student) {
studentService.updateStudent(student);
}
@DeleteMapping("/{studentId}")
public void deleteStudent(@PathVariable Long studentId) {
studentService.deleteStudent(studentId);
}
}
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import java.util.List;
@RestController
@RequestMapping("/api/students")
public class StudentController {
@Autowired
private StudentService studentService;
@GetMapping
public List<Student> getAllStudents() {
return studentService.getAllStudents();
}
@GetMapping("/{studentId}")
public Student getStudentById(@PathVariable Long studentId) {
return studentService.getStudentById(studentId);
}
@PostMapping
public void addStudent(@RequestBody Student student) {
