圖書管理系統(tǒng)是現(xiàn)代化圖書管理的重要工具之一，它可以幫助管理員更高效地管理圖書館內(nèi)的圖書資料。為了方便管理員的工作，我們開發(fā)了基于Java和MySQL的圖書管理系統(tǒng)，以下是源碼部分的介紹。

// 連接數(shù)據(jù)庫
public void connect() throws SQLException {
String url = "jdbc:mysql://localhost:3306/library";
String user = "root";
String password = "123456";
connection = DriverManager.getConnection(url, user, password);
}
// 添加圖書信息
public void addBook(Book book) throws SQLException {
String insertQuery = "INSERT INTO books (title, author, publisher, publishDate) " +
"VALUES (?, ?, ?, ?)";
PreparedStatement preparedStatement = connection.prepareStatement(insertQuery);
preparedStatement.setString(1, book.getTitle());
preparedStatement.setString(2, book.getAuthor());
preparedStatement.setString(3, book.getPublisher());
preparedStatement.setDate(4, book.getPublishDate());
preparedStatement.executeUpdate();
}
// 刪除圖書信息
public void deleteBook(int bookId) throws SQLException {
String deleteQuery = "DELETE FROM books WHERE id=?";
PreparedStatement preparedStatement = connection.prepareStatement(deleteQuery);
preparedStatement.setInt(1, bookId);
preparedStatement.executeUpdate();
}
// 修改圖書信息
public void updateBook(Book book) throws SQLException {
String updateQuery = "UPDATE books SET title=?, author=?, publisher=?, publishDate=? WHERE id=?";
PreparedStatement preparedStatement = connection.prepareStatement(updateQuery);
preparedStatement.setString(1, book.getTitle());
preparedStatement.setString(2, book.getAuthor());
preparedStatement.setString(3, book.getPublisher());
preparedStatement.setDate(4, book.getPublishDate());
preparedStatement.setInt(5, book.getId());
preparedStatement.executeUpdate();
}
// 查詢圖書信息
public ListsearchBook(String keyword) throws SQLException {
String searchQuery = "SELECT * FROM books WHERE title LIKE ? " +
"OR author LIKE ? OR publisher LIKE ?";
PreparedStatement preparedStatement = connection.prepareStatement(searchQuery);
preparedStatement.setString(1, "%" + keyword + "%");
preparedStatement.setString(2, "%" + keyword + "%");
preparedStatement.setString(3, "%" + keyword + "%");
ResultSet resultSet = preparedStatement.executeQuery();
Listbooks = new ArrayList<>();
while (resultSet.next()) {
Book book = new Book();
book.setId(resultSet.getInt("id"));
book.setTitle(resultSet.getString("title"));
book.setAuthor(resultSet.getString("author"));
book.setPublisher(resultSet.getString("publisher"));
book.setPublishDate(resultSet.getDate("publishDate"));
books.add(book);
}
return books;
}

以上是Java MySQL圖書管理系統(tǒng)源碼部分的介紹，其中包括連接數(shù)據(jù)庫、添加、刪除、修改、查詢等基本操作。通過這些代碼，我們可以更加方便地對圖書館內(nèi)的圖書信息進行管理，大大提高了工作效率。
