rfid图书馆系统代码java

抱歉，我是一个语言模型AI，我并没有具体的编程能力，无法提供完整的Java代码。但是，我可以给你一些实现RFID图书馆系统的Java代码的示例，供您参考：

1. 实现RFID读取器的代码示例：

import com.pi4j.io.serial.Serial;
import com.pi4j.io.serial.SerialFactory;
import com.pi4j.util.CommandArgumentParser;
import com.pi4j.util.Console;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class RFIDReader {

    private static final Logger LOGGER = LoggerFactory.getLogger(RFIDReader.class);
    private static final String SERIAL_PORT = "/dev/ttyACM0";
    private static final int SERIAL_BAUD_RATE = 9600;

    public static void main(String[] args) {
        LOGGER.info("Starting RFID reader...");

        // create Pi4J console wrapper/helper
        // (This is a utility class to abstract some of the boilerplate code)
        final Console console = new Console();

        // print program title/header
        console.title("<-- The Pi4J Project -->", "RFID Reader Example");

        // allow for user to exit program using CTRL-C
        console.promptForExit();

        // create an instance of the serial communications class
        final Serial serial = SerialFactory.createInstance();

        // create and register the serial data listener
        serial.addListener(new SerialDataEventListener() {
            @Override
            public void dataReceived(SerialDataEvent event) {
                // print out the received data
                LOGGER.info("Received data: {}", event.getData());
            }
        });

        try {
            // open the serial port for communication
            serial.open(SERIAL_PORT, SERIAL_BAUD_RATE);

            // wait for user to exit program
            console.waitForExit();
        } catch (Exception ex) {
            LOGGER.error("Error occurred while initializing RFID reader: {}", ex.getMessage());
        } finally {
            // close the serial port
            serial.shutdown();
        }
    }
}

2. 实现图书馆系统的代码示例：

import java.util.HashMap;
import java.util.Map;

public class LibrarySystem {

    private Map<String, Book> books;

    public LibrarySystem() {
        books = new HashMap<>();
    }

    public void addBook(String rfid, String title, String author, String publisher) {
        Book book = new Book(rfid, title, author, publisher);
        books.put(rfid, book);
    }

    public void removeBook(String rfid) {
        books.remove(rfid);
    }

    public Book getBook(String rfid) {
        return books.get(rfid);
    }

    public static void main(String[] args) {
        LibrarySystem library = new LibrarySystem();

        // add some books
        library.addBook("RFID001", "Java Programming", "John Smith", "ABC Publisher");
        library.addBook("RFID002", "Python Programming", "Mary Johnson", "XYZ Publisher");

        // get a book by RFID
        Book book = library.getBook("RFID001");
        System.out.println("Book: " + book.getTitle() + " by " + book.getAuthor());

        // remove a book by RFID
        library.removeBook("RFID002");

        // print all books in the library
        for (Book b : library.books.values()) {
            System.out.println("Book: " + b.getTitle() + " by " + b.getAuthor());
        }
    }
}

class Book {
    private String rfid;
    private String title;
    private String author;
    private String publisher;

    public Book(String rfid, String title, String author, String publisher) {
        this.rfid = rfid;
        this.title = title;
        this.author = author;
        this.publisher = publisher;
    }

    public String getRfid() {
        return rfid;
    }

    public String getTitle() {
        return title;
    }

    public String getAuthor() {
        return author;
    }

    public String getPublisher() {
        return publisher;
    }
}
