文章展示了如何在Java中使用BookDaoImpl类的saveBook方法，对Book对象进行属性设置并将其保存到数据库，涉及实体对象和日期处理。

 public static void main(String[] args) {
        BookDaoImpl dao = new BookDaoImpl();
        Book book = new Book();
        book.setBook_name("面纱");
        book.setAuthor("毛姆");
        book.setPrice(new BigDecimal(69.9));
        book.setLanguage("中文");
        Calendar calendar = Calendar.getInstance();
        calendar.set(1977,4,6);
        book.setPubdate(calendar.getTime());
        book.setIntroduction("一个神秘的故事");
        book.setIsbn("xxxx821xxxx");
        book.setPressmark("4-3-07");
        book.setPublish("清华出版社");
        dao.saveBook(book);
    }

@Test
    void testsaveBook() {
        BookDaoImpl dao = new BookDaoImpl();
        Book book = new Book();
        book.setBook_name("面纱");
        book.setAuthor("毛姆");
        book.setPrice(new BigDecimal(69.9));
        book.setLanguage("中文");
        Calendar calendar = Calendar.getInstance();
        calendar.set(1977,4,6);
        book.setPubdate(calendar.getTime());
        book.setIntroduction("一个神秘的故事");
        book.setIsbn("xxxx821xxxx");
        book.setPressmark("4-3-07");
        book.setPublish("清华出版社");
     dao.saveBook(book);
}
