Project Structure Technology Stack: Java 8 Spring Framework (Spring Boot, Spring MVC, Spring Data JPA) Hibernate ORM MySQL/PostgreSQL (or any other relational database) Thymeleaf (for front-end rendering) Maven (for project management) Apache Tomcat (for deployment)

Steps to Develop the Application Set Up Development Environment:

Install Java 8. Set up your IDE (IntelliJ IDEA, Eclipse, etc.). Install and configure Maven. Set up a database (MySQL/PostgreSQL). Create a New Spring Boot Project:

Use Spring Initializr (https://start.spring.io/) to generate a new Spring Boot project with dependencies: Spring Web, Spring Data JPA, Thymeleaf, and MySQL/PostgreSQL Driver. Download and import the project into your IDE. Configure Application Properties:

Open src/main/resources/application.properties (or application.yml) and configure your database connection: properties Copy code spring.datasource.url=jdbc:mysql://localhost:3306/university_admissions spring.datasource.username=root spring.datasource.password=yourpassword spring.jpa.hibernate.ddl-auto=update spring.jpa.show-sql=true Create Database Entities:

Define your entities to represent tables such as Student, Application, Course, and Department. java Copy code @Entity public class Student { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; private String name; private String email; private String password;

// Getters and setters

}

@Entity public class Application { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; private String status;

@ManyToOne
@JoinColumn(name = "student_id")
private Student student;

@ManyToOne
@JoinColumn(name = "course_id")
private Course course;

// Getters and setters

}

@Entity public class Course { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; private String name; private String description;

@ManyToOne
@JoinColumn(name = "department_id")
private Department department;

// Getters and setters

}

@Entity public class Department { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; private String name;

// Getters and setters

} Create Repositories:

Create repository interfaces for your entities. java Copy code public interface StudentRepository extends JpaRepository<Student, Long> {} public interface ApplicationRepository extends JpaRepository<Application, Long> {} public interface CourseRepository extends JpaRepository<Course, Long> {} public interface DepartmentRepository extends JpaRepository<Department, Long> {} Create Services:

Implement service classes to handle business logic. java Copy code @Service public class StudentService { @Autowired private StudentRepository studentRepository;

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

public Student getStudentById(Long id) {
    return studentRepository.findById(id).orElse(null);
}

public Student saveStudent(Student student) {
    return studentRepository.save(student);
}

}

@Service public class ApplicationService { @Autowired private ApplicationRepository applicationRepository;

public List<Application> getAllApplications() {
    return applicationRepository.findAll();
}

public Application getApplicationById(Long id) {
    return applicationRepository.findById(id).orElse(null);
}

public Application saveApplication(Application application) {
    return applicationRepository.save(application);
}

} Create Controllers:

Create controllers to handle HTTP requests. java Copy code @Controller public class StudentController { @Autowired private StudentService studentService;

@GetMapping("/students")
public String getAllStudents(Model model) {
    model.addAttribute("students", studentService.getAllStudents());
    return "students";
}

@GetMapping("/students/{id}")
public String getStudentById(@PathVariable Long id, Model model) {
    model.addAttribute("student", studentService.getStudentById(id));
    return "student";
}

@GetMapping("/students/new")
public String createStudentForm(Model model) {
    model.addAttribute("student", new Student());
    return "create_student";
}

@PostMapping("/students")
public String saveStudent(@ModelAttribute Student student) {
    studentService.saveStudent(student);
    return "redirect:/students";
}

}

@Controller public class ApplicationController { @Autowired private ApplicationService applicationService;

@GetMapping("/applications")
public String getAllApplications(Model model) {
    model.addAttribute("applications", applicationService.getAllApplications());
    return "applications";
}

@GetMapping("/applications/{id}")
public String getApplicationById(@PathVariable Long id, Model model) {
    model.addAttribute("application", applicationService.getApplicationById(id));
    return "application";
}

@GetMapping("/applications/new")
public String createApplicationForm(Model model) {
    model.addAttribute("application", new Application());
    return "create_application";
}

@PostMapping("/applications")
public String saveApplication(@ModelAttribute Application application) {
    applicationService.saveApplication(application);
    return "redirect:/applications";
}

} Create Thymeleaf Templates:

Create Thymeleaf templates for the views (e.g., students.html, student.html, create_student.html). html Copy code

<title>Students</title>

Students List

ID	Name	Email
1	John Doe	john@example.com

Run the Application:

Run the Spring Boot application. Open your browser and navigate to http://localhost:8080/students to see the list of students. Deploy the Application:

Package your application as a WAR file using Maven: sh Copy code mvn clean package Deploy the WAR file to an Apache Tomcat server or any other servlet container. Additional Features Authentication and Authorization: Implement Spring Security for user login and access control. Form Validation: Add validation for forms using Hibernate Validator. REST API: Expose RESTful endpoints for the application if needed. Front-End Frameworks: Optionally integrate with front-end frameworks like Angular or React for a more dynamic user experience. Conclusion This guide provides a foundational structure for building a University Admission Management System using Java 8 with Spring and Hibernate frameworks. Each step can be expanded with more complex features and refinements based on specific requirements.
