}

book包：

 

bookbiz接口：

package com.book.biz;

import java.util.List;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.springframework.orm.hibernate5.HibernateCallback;

import com.book.entity.Book;

public interface BookBiz {
    public int add(Book book);
    public void edit(Book book);

    public void del(Book book);

    public List<Book> list();
    
}

实现类：

package com.book.biz;

import java.util.List;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.springframework.orm.hibernate5.HibernateCallback;

import com.book.entity.Book;

public interface BookBiz {
    public int add(Book book);
    public void edit(Book book);

    public void del(Book book);

    public List<Book> list();
    
}

bookdao：

package com.book.dao;

import java.util.List;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.springframework.orm.hibernate5.HibernateCallback;

import com.base.dao.Basedao;
import com.book.entity.Book;
/**
 * 一定要继承Basedao（是为了获取到hibernateTemplete）
 * 方法命名有讲究（一定要符合声明式事务所定义的规则）
 * hibernateTemplete模板在执行查询的时候比较特殊
 * 
 * @author 11
 *
 */
public class BookDao extends Basedao{
public int add(Book book) {
    return (int) getHibernateTemplate().save(book);
}

public void edit(Book book) {
    
    getHibernateTemplate().update(book);
}

public void del(Book book) {
    getHibernateTemplate().delete(book);
}

public List<Book> list(){
    return (List<Book>) getHibernateTemplate().execute(new HibernateCallback<List<Book>>() {

        @Override
        public List<Book> doInHibernate(Session session) throws HibernateException {
            // TODO Auto-generated method stub
            return session.createQuery("from Book").list();    
        }
    });
}

}

然后再是实体类与映射文件的导入

 

 最后再是bookaction

package com.book.web;

import java.util.List;

import com.base.web.BaseAction;
import com.book.biz.BookBiz;
import com.book.entity.Book;
import com.opensymphony.xwork2.ModelDriven;

public class BookAction extends BaseAction implements ModelDriven<Book> {
   private Book book=new Book();
   private BookBiz bookbiz;
public BookBiz getBookbiz() {
    return bookbiz;
}


public void setBookbiz(BookBiz bookbiz) {
    this.bookbiz = bookbiz;
}


@Override
public Book getModel() {
    // TODO Auto-generated method stub
    return book;
} 


public String add() {
    System.out.println(book);
    this.bookbiz.add(book);
    return null;
}


public String edit() {
    System.out.println(book);
    this.bookbiz.edit(book);
    return null;
}



public String del() {
    System.out.println(book);
    this.bookbiz.del(book);
    return null;
}


public String list() {
    List<Book> list2=this.bookbiz.list();
    for (Book book : list2) {
        System.out.println(book);
    }

    return null;
}










}
