基于Java+SpringBoot+vue+elementui图书商城系统设计实现

由于问题描述涉及的内容较多，且没有明确的代码问题，我将提供一个基于Spring Boot和Vue的简单图书管理系统的后端部分的代码示例。

// BookController.java
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import java.util.List;
 
@RestController
@RequestMapping("/api/books")
public class BookController {
 
    private final BookService bookService;
 
    @Autowired
    public BookController(BookService bookService) {
        this.bookService = bookService;
    }
 
    @GetMapping
    public List<Book> getAllBooks() {
        return bookService.findAll();
    }
 
    @PostMapping
    public Book createBook(@RequestBody Book book) {
        return bookService.save(book);
    }
 
    @GetMapping("/{id}")
    public Book getBookById(@PathVariable(value = "id") Long bookId) {
        return bookService.findById(bookId);
    }
 
    @PutMapping("/{id}")
    public Book updateBook(@PathVariable(value = "id") Long bookId, @RequestBody Book bookDetails) {
        bookDetails.setId(bookId);
        return bookService.save(bookDetails);
    }
 
    @DeleteMapping("/{id}")
    public String deleteBook(@PathVariable(value = "id") Long bookId) {
        bookService.deleteById(bookId);
        return "Book deleted successfully";
    }
}
 
// BookService.java
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Service;
 
@Service
public class BookService {
    private final BookRepository bookRepository;
 
    @Autowired
    public BookService(BookRepository bookRepository) {
        this.bookRepository = bookRepository;
    }
 
    public List<Book> findAll() {
        return bookRepository.findAll();
    }
 
    public Book findById(Long id) {
        return bookRepository.findById(id).orElse(null);
    }
 
    public Book save(Book book) {
        return bookRepository.save(book);
    }
 
    public void deleteById(Long id) {
        bookRepository.deleteById(id);
    }
}
 
// Book.java (Entity)
import javax.
