Whether the test framework is OK
Test path jump, whether the mapping address is correct
Front-end new folder: jsp, js, image
The Jsp folder places the jsp page
Add in the Web.xml file: < welcome-file > index.jsp </ welcome-file >

The result is as follows:
Next, test whether the before and after of the book work properly:
With the above path: < p >< a href = " <%= basePath %> book/getAllBook.do" > manage books </ a ></ p >

System.out.println("bookManager.getAllBook()--------"+bookManager.getAllBook());
request.setAttribute("bookList", bookManager.getAllBook());
return basePath+"book_list";

Create a new book folder under the jsp folder to place the addition, deletion, modification and query of the book
booklist.jsp

Reason for error:
The Book in BookDaoImpl was written as a lowercase book before
Replace book in the hql statement in BookDaoImpl with Book
String hql = "from book u where u.id=?";
Modify BookDaoImpl.java

import org.hibernate.SessionFactory;
import com.test.entity.Book;
public class BookDaoImpl implements BookDao{
private SessionFactory sessionFactory;
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
@Override
publicBook getBook(String id) {
//TODO Auto-generated method stub
String hql = "from Book u where u.id=?";
Query query = sessionFactory.getCurrentSession().createQuery(hql);
query.setString(0, id);
return (Book)query.uniqueResult();
}
@Override
