ssh框架概述
SSH是 struts+spring+hibernate的一个集成框架，是目前比较流行的一种Web应用程序开源框架。区别于 Secure Shell 。
SSH框架存在意义
框架的使用可以大大缩短大型系统的开发周期，提高开发质量，就传统的Java编程来说，基于类库的面向对象的技术来比较，框架已经为我们封住这些代码，在开发的过程中，只要能够调用这些已经写好的类或接口，来实现其中的方法，或者重写其中的方法，使其为我们的工作服务，那么就可以节省我们的开发周期。使工作更加高效有序地进行。
SSH框架的整合步骤：
导入所需要的pom依赖

Biz层（BookBiz与它的实现类BookBizipml）
接口类
package com.ht.book.biz;
import java.util.List;
import com.ht.book.entity.Book;
public interface BookBiz {
/**
* 新增
* @param book
* @return
*/
public int add(Book book);
/**
* 查询所有
* @return
*/
public List<Book> list();
}
实现类
package com.ht.book.biz.ipml; import java.util.List; import com.ht.book.biz.BookBiz;
import com.ht.book.dao.BookDao;
import com.ht.book.entity.Book; public class BookBizipml implements BookBiz {

} public void setBookDao(BookDao bookDao) {
this.bookDao = bookDao;
} @Override
public int add(Book book) {
return bookDao.add(book);
} @Override
public List<Book> list() {
return bookDao.list();
} }
Dao层（BookDao）
package com.ht.book.dao; import java.util.List; import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.springframework.orm.hibernate5.HibernateCallback; import com.ht.base.dao.BaseDao;
import com.ht.book.entity.Book; public class BookDao extends BaseDao{ /**

public int add(Book book) {
return (int) this.getHibernateTemplate().save(book);

@Override
public List<Book> doInHibernate(Session session) throws HibernateException {
return session.createQuery("from Book").list();
}
});
}
}
web控制层（展示新增和查询方法 BookAction）
package com.ht.book.web; import java.util.List; import com.ht.base.web.BaseAction;
import com.ht.book.biz.BookBiz;
import com.ht.book.entity.Book;
import com.opensymphony.xwork2.ModelDriven; public class BookAction extends BaseAction implements ModelDriven<Book>{
//book实现了ModelDriven接口，意味着封装了jsp传递到后台所有参数，详情参见struts
private static final long serialVersionUID = -5631093170850951408L; private Book book=new Book();
private BookBiz bookBiz; public BookBiz getBookBiz() {
return bookBiz;
} public void setBookBiz(BookBiz bookBiz) {
this.bookBiz = bookBiz;
} public String add() {
this.bookBiz.add(book);
return null;
} public String list() {
List<Book> list2 = this.bookBiz.list();
for (Book book : list2) {
System.out.println(book);
}
return null;
} @Override
public Book getModel() {
// TODO Auto-generated method stub
return book;
}
}
