8.加载struts框架，并加载所需要的jar包。
9.创建DAO,BaseDAO.java,IBookDAO.java,ICatalogDAO.java,IUserDAO.java
BaseDAO.java代码如下：
packageorg.apex.bookstore.dao;
importorg.hibernate.SessionFactory;
importorg.hibernate.classic.Session;
publicclassBaseDAO{
privateSessionFactorysessionFactory;
publicSessionFactorygetSessionFactory（）{
returnsessionFactory;
}
publicvoidsetSessionFactory（SessionFactorysessionFactory）{
this.sessionFactory=sessionFactory;
}
publicSessiongetSession（）{
Sessionsession=sessionFactory.openSession（）;
returnsession;
}
}
IBookDAO.java代码如下：
packageorg.apex.bookstore.dao;
importjava.util.List;
importorg.apex.bookstore.vo.Book;
publicinterfaceIBookDAO{
publicListgetBookByCatalogid（Integercatalogid）;
publicListgetBookByCatalogidPaging（Integercatalogid,intcurrentPage,intpageSize）;
publicintgetTotalByCatalog（Integercatalogid）;
publicBookgetBookById（Integerbookid）;
publicListgetRequiredBookByHql（Stringhql）;
publicListgetNewBook（）;
}
ICatalogDAO.java代码如下：
packageorg.apex.bookstore.dao;
importjava.util.List;
publicinterfaceICatalogDAO{
publicListgetAllCatalogs（）;
}
IUserDAO.java代码如下：
packageorg.apex.bookstore.dao;
importorg.apex.bookstore.vo.User;
publicinterfaceIUserDAO{
publicvoidsaveUser（Useruser）;
publicUservalidateUser（Stringusername,Stringpassword）;
publicbooleanexitUser（Stringusername）;
}
10.创建service，IBookService.java,ICatalogService.java,IUserService.java
IBookService.java代码如下：
packageorg.apex.bookstore.service;
importjava.util.List;
importorg.apex.bookstore.vo.Book;
publicinterfaceIBookService{
publicListgetBookByCatalogid（Integercatalogid）;
publicListgetBookByCatalogidPaging（Integercatalogid,intcurrentPage,intpageSize）;
publicintgetTotalByCatalog（Integercatalogid）;
publicBookgetBookById（Integerbookid）;
publicListgetRequiredBookByHql（Stringhql）;
publicListgetNewBook（）;
}
ICatalogService.java代码如下：
packageorg.apex.bookstore.service;
importjava.util.List;
publicinterfaceICatalogService{
publicListgetAllCatalogs（）;
}
IUserService.java代码如下：
packageorg.apex.bookstore.service;
importorg.apex.bookstore.vo.User;
publicinterfaceIUserService{
publicvoidsaveUser（Useruser）;
publicUservalidateUser（Stringusername,Stringpassword）;
publicbooleanexitUser（Stringusername）;
}
11.创建action，包括BookAction.java和UserAction.java
BookAction.java代码如下：
packageorg.apex.bookstore.action;
importjava.util.List;
importjava.util.Map;
importorg.apex.bookstore.service.IBookService;
importorg.apex.bookstore.service.ICatalogService;
importorg.apex.bookstore.util.Pager;
importcom.opensymphony.xwork2.ActionContext;
importcom.opensymphony.xwork2.ActionSupport;
publicclassBookActionextendsActionSupport{
protectedICatalogServicecatalogService;
protectedIBookServicebookService;
protectedIntegercatalogid;
privateIntegercurrentPage=1;
privateStringbookname;
privateintminPrice;
privateintmaxPrice;
publicIntegergetCatalogid（）{
returncatalogid;
}
publicvoidsetCatalogid（Integercatalogid）{
this.catalogid=catalogid;
}
publicICatalogServicegetCatalogService（）{
returncatalogService;
}
publicvoidsetCatalogService（ICatalogServicecatalogService）{
this.catalogService=catalogService;
}
publicStringbrowseCatalog（）throwsException{
Listcatalogs=catalogService.getAllCatalogs（）;
Maprequest=（Map）ActionContext.getContext（）.get（"request"）;
request.put（"catalogs",catalogs）;
returnSUCCESS;
}
publicStringbrowseBookPaging（）throwsException{
inttotalSize=bookService.getTotalByCatalog（catalogid）;
Pagerpager=newPager（currentPage,totalSize）;
//Listbooks=bookService.getBookByCatalogid（catalogid）;
Listbooks=bookService.getBookByCatalogidPaging（catalogid,currentPage,pager.getPageSize（））;
Maprequest=（Map）ActionContext.getContext（）.get（"request"）;
request.put（"books",books）;
request.put（"pager",pager）;
//购物车要返回时,需要记住返回的地址
Mapsession=ActionContext.getContext（）.getSession（）;
request.put（"catalogid",catalogid）;
returnSUCCESS;
}
publicStringbrowseBook（）throwsException{
Listbooks=bookService.getBookByCatalogid（catalogid）;
Maprequest=（Map）ActionContext.getContext（）.get（"request"）;
request.put（"books",books）;
returnSUCCESS;
}
publicStringsearchBook（）throwsException{
StringBufferhql=newStringBuffer（"fromBookb"）;
if（bookname!
=null&&bookname.length（）!
=0）
hql.append（"whereb.booknamelike'%"+bookname+"%'"）;
//if（minPrice!
=0&&maxPrice!
=0）
//hql.append（"andb.price>"+minPrice+"andb.price<"+maxPrice）;
Listbooks=bookService.getRequiredBookByHql（hql.toString（））;
Maprequest=（Map）ActionContext.getContext（）.get（"request"）;
System.out.println（hql）;
System.out.println（bookname）;
request.put（"books",books）;
returnSUCCESS;
}
publicStringnewBook（）throwsException{
Listbooks=bookService.getNewBook（）;
Maprequest=（Map）ActionContext.getContext（）.get（"request"）;
request.put（"books",books）;
returnSUCCESS;
}
publicIBookServicegetBookService（）{
returnbookService;
}
publicvoidsetBookService（IBookServicebookService）{
this.bookService=bookService;
}
publicIntegergetCurrentPage（）{
returncurrentPage;
}
publicvoidsetCurrentPage（IntegercurrentPage）{
this.currentPage=currentPage;
}
publicStringgetBookname（）{
returnbookname;
}
publicvoidsetBookname（Stringbookname）{
this.bookname=bookname;
}
}
UserAction.java代码如下：
