Java Web图书馆管理系统通常包含几个关键组件:用户界面、后台管理逻辑和服务端数据持久化。下面是一个非常基础的框架示例:
1. **实体类(Book.java)**:
```java
public class Book {
private int id;
private String title;
private String author;
private Date publicationDate;
// getter和setter方法
}
```
2. **DAO(LibraryDAO.java)** 或者 **Repository(BookRepository.java)**:
```java
import org.springframework.data.jpa.repository.JpaRepository;
public interface BookRepository extends JpaRepository<Book, Integer> {
List<Book> findAll();
Book findById(int id);
// 其他CRUD操作
}
```
3. **Service(LibraryService.java)**:
```java
@Service
public class LibraryService {
private final BookRepository repository;
public LibraryService(BookRepository repository) {
this.repository = repository;
}
public List<Book> getAllBooks() { return repository.findAll(); }
public Book getBookById(int id) { return repository.findById(id).orElse(null); }
// 添加、更新、删除操作
}
```
4. **Controller(BookController.java)**:
```java
@RestController
@RequestMapping("/api/books")
public class BookController {
@Autowired
private LibraryService service;
@GetMapping
public ResponseEntity<List<Book>> getAllBooks() {
return new ResponseEntity<>(service.getAllBooks(), HttpStatus.OK);
}
// 添加其他HTTP方法如GET, POST, PUT, DELETE来操作单个书记录
}
```
5. **HTML/JSP** 用户界面展示:
```jsp
<table>
<thead>
<tr>
<th>ID</th>
<th>Title</th>
<th>Author</th>
<th>Date</th>
</tr>
</thead>
<tbody>
<c:forEach items="${books}" var="book">
<tr>
<td>${book.id}</td>
<td>${book.title}</td>
<td>${book.author}</td>
<td>${book.publicationDate}</td>
</tr>
</c:forEach>
</tbody>
</table>
```
6. **Spring MVC** 或 **Spring Boot** 配置:
- 配置Spring Data JPA
- 定义Thymeleaf或其他视图技术
