struts+spring+hibernate的web应用<四> Web层代码编写(1)

前面的文章：

struts+spring+hibernate 的 web 应用 < 一 > 架构搭建

struts+spring+hibernate 的 web 应用 < 二 > Dao 层代码编写

struts+spring+hibernate 的 web 应用 < 三 > Service 层代码编写

 

Web 层代码量比较大，涉及的地方也比较多，考虑到文章过于庞大，所以分两篇写。
我们还是先从主要的 action 开始吧。

在 com.game.products.web.actions 包中新建 ProductsAction ，这是一个 DispatchAction ，代码如下：

 

package  com.game.products.web.actions;

import  java.util.List;

import  javax.servlet.http.HttpServletRequest;
import  javax.servlet.http.HttpServletResponse;

import  org.acegisecurity.AccessDeniedException;
import  org.apache.struts.action.ActionForm;
import  org.apache.struts.action.ActionForward;
import  org.apache.struts.action.ActionMapping;
import  org.apache.struts.actions.DispatchAction;

import  com.game.commons.Pager;
import  com.game.commons.PagerService;
import  com.game.products.model.Products;
import  com.game.products.services.iface.ProductsService;
import  com.game.products.web.forms.ProductsForm;


public   class  ProductsAction  extends  DispatchAction  {
    
     private  ProductsService productsService;
     private  PagerService pagerService;
    
     /**  
     * 显示所有信息
      */
     public  ActionForward doGetProducts(
            ActionMapping mapping,
            ActionForm form,
            HttpServletRequest req,
            HttpServletResponse res) {
        String flag = req.getParameter( " flag " );
        
         int  totalRows = productsService.getRows();
        String currentPage = req.getParameter( " currentPage " );
        String pagerMethod = req.getParameter( " pagerMethod " );
        
        Pager pager = pagerService.getPager(currentPage, pagerMethod, totalRows);
        
        List productsList = productsService.getProducts(pager.getPageSize(), pager.getStartRow());
        
        req.setAttribute( " productsList " , productsList);
        req.setAttribute( " PAGER " , pager);
        req.setAttribute( " flag " , flag);
        req.setAttribute( " totalRows " , String.valueOf(totalRows));
        
         return  mapping.findForward( " all " );
    }
    
     /**

            req.setAttribute( " fieldname " , fieldname);
            req.setAttribute( " value " , value);
        }
        
        Products pd = productsService.getProduct(gameId);
        req.setAttribute( " pd " , pd);

    }

     public   void  setProductsService(ProductsService productsService)  {
         this .productsService  =  productsService;
    }

     public  PagerService getPagerService()  {
         return  pagerService;
    }

     public   void  setPagerService(PagerService pagerService)  {
         this .pagerService  =  pagerService;
    }
    
}

 

在 com.game.products.web.forms 包中新建 ProductsForm ，他继承了 ValidatorForm 。代码如下：

 

package  com.game.products.web.forms;

import  javax.servlet.http.HttpServletRequest;

import  org.apache.struts.action.ActionMapping;
import  org.apache.struts.validator.ValidatorForm;

public   class  ProductsForm  extends  ValidatorForm  {
     //     Fields 
     private  String gameId; // 编号
     private  String gameNameCn; // 中文名称
     private  String gameNameEn; // 英文名称
     private  String gameCapacity; // 碟数
     private  String gameVersion; // 版本
     private  String gameMedia; // 介质
     private  String gameCopyright; // 版权
     private  String gamePrice; // 价格
     private  String gameContent; // 攻略
    
     private  String flag;
     private  String fieldname;
     private  String value;
    
     //     Constructors
     public  ProductsForm() {
        gameId = null ;
        gameNameCn = null ;
        gameNameEn = null ;
        gameCapacity = null ;
        gameVersion = null ;
        gameMedia = null ;
        gameCopyright = null ;
        gamePrice = null ;
        gameContent = null ;
        
        flag = null ;
        fieldname = null ;
        value = null ;
    }
    
     //  reset
     public   void  reset(ActionMapping mapping, HttpServletRequest request)  {
        gameId = null ;
        gameNameCn = null ;
        gameNameEn = null ;
        gameCapacity = null ;
        gameVersion = null ;
        gameMedia = null ;
        gameCopyright = null ;
        gamePrice = null ;
        gameContent = null ;
        
        flag = null ;
        fieldname = null ;
        value = null ;
    }
    
     //     Property accessors
     public  String getGameCapacity()  {
         return  gameCapacity;
    }

     public   void  setGameCapacity(String gameCapacity)  {
         this .gameCapacity  =  gameCapacity;
    }

     public  String getGameId()  {
         return  gameId;
    }

     public   void  setGameId(String gameId)  {
         this .gameId  =  gameId;
    }

     public  String getGameNameCn()  {
         return  gameNameCn;
    }

     public   void  setGameNameCn(String gameNameCn)  {
         this .gameNameCn  =  gameNameCn;
    }

     public  String getGameNameEn()  {
         return  gameNameEn;
    }

     public   void  setGameNameEn(String gameNameEn)  {
         this .gameNameEn  =  gameNameEn;
    }

     public  String getGameVersion()  {
         return  gameVersion;
    }

     public   void  setGameVersion(String gameVersion)  {
         this .gameVersion  =  gameVersion;
    }

     public  String getGameMedia()  {
         return  gameMedia;
    }

     public   void  setGameMedia(String gameMedia)  {
         this .gameMedia  =  gameMedia;
    }

     public  String getFieldname()  {
         return  fieldname;
    }

     public   void  setFieldname(String fieldname)  {
         this .fieldname  =  fieldname;
    }

     public  String getFlag()  {
         return  flag;
    }

     public   void  setFlag(String flag)  {
         this .flag  =  flag;
    }

     public  String getValue()  {
         return  value;
    }

     public   void  setValue(String value)  {
         this .value  =  value;
    }

     public  String getGameCopyright()  {
         return  gameCopyright;
    }

     public   void  setGameCopyright(String gameCopyright)  {
         this .gameCopyright  =  gameCopyright;
    }

     public  String getGameContent()  {
         return  gameContent;
    }

     public   void  setGameContent(String gameContent)  {
         this .gameContent  =  gameContent;
    }

     public  String getGamePrice()  {
         return  gamePrice;
    }

     public   void  setGamePrice(String gamePrice)  {
         this .gamePrice  =  gamePrice;
    }

}

 

 

接着编写配置文件。

在 struts-config 包中新建 struts-config.xml 。代码如下：

<? xml version="1.0" encoding="ISO-8859-1" ?>
<! DOCTYPE struts-config PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN"
    "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd" >

< struts-config >
     < form-beans >
         < form-bean  name ="productsForm"  type ="com.game.products.web.forms.ProductsForm"   />
     </ form-beans >
    
     < global-forwards >
         < forward  name ="success"  path ="/products/product_success.jsp"   />
         < forward  name ="failure"  path ="/products/product_failure.jsp"   />
     </ global-forwards >
    
     < action-mappings >
         < action  path ="/getProducts"  type ="org.springframework.web.struts.DelegatingActionProxy"  parameter ="method"  scope ="request"  validate ="false" >
             < forward  name ="all"  path ="/products/products.jsp"   />
         </ action >
         < action  path ="/getProduct"  type ="org.springframework.web.struts.DelegatingActionProxy"  parameter ="method"  scope ="request"  validate ="false" >
             < forward  name ="one"  path ="/products/product.jsp"   />
         </ action >
         < action  path ="/deleteProduct"  type ="org.springframework.web.struts.DelegatingActionProxy"  parameter ="method"  scope ="request"  validate ="false" >             
         </ action >
         < action  path ="/addProductPage"  type ="org.springframework.web.struts.DelegatingActionProxy"  parameter ="method"  scope ="request"  validate ="false" >
             < forward  name ="add"  path ="/products/addproduct.jsp"   />
         </ action >
         < action  path ="/addProduct"  name ="productsForm"  type ="org.springframework.web.struts.DelegatingActionProxy"  parameter ="method"  scope ="request"  validate ="false"  input ="/product_failure.jsp" >
         </ action >
         < action  path ="/updateProduct"  name ="productsForm"  type ="org.springframework.web.struts.DelegatingActionProxy"  parameter ="method"  scope ="request"  validate ="false"  input ="/product_failure.jsp" >
         </ action >
        
         < action  path ="/returnProduct"  type ="org.springframework.web.struts.DelegatingActionProxy"  parameter ="method"  scope ="request"  validate ="false" >
             < forward  name ="all"  path ="/products/products.jsp"   />
         </ action >
         < action  path ="/queryProducts"  type ="org.springframework.web.struts.DelegatingActionProxy"  parameter ="method"  scope ="request"  validate ="false" >
             < forward  name ="all"  path ="/products/products.jsp"   />
         </ action >
     </ action-mappings >
    
     < message-resources  parameter ="com.game.resources.ApplicationResourcesProducts"   />
    
     < plug-in  className ="org.apache.struts.validator.ValidatorPlugIn" >
         < set-property  property ="pathnames"
            value ="/WEB-INF/struts-validator/validator-rules.xml,/WEB-INF/struts-validator/validation.xml" />
     </ plug-in >     
    
</ struts-config >

 

需要注意的是，这里的 action 交由 spring 的 DelegatingActionProxy 管理了。

 

打开 applicationContext.xml ，接着添加如下代码：

<!--  View  -->
     < bean  name ="/getProducts"  class ="com.game.products.web.actions.ProductsAction"  singleton ="false" >
         < property  name ="productsService" >
             < ref  bean ="productsService" />
         </ property >
         < property  name ="pagerService" >
             < ref  bean ="pagerService" />
         </ property >
     </ bean >
     < bean  name ="/getProduct"  class ="com.game.products.web.actions.ProductsAction"  singleton ="false" >

         </ property >
         < property  name ="pagerService" >
             < ref  bean ="pagerService" />
         </ property >
     </ bean >

大家可能注意到了这里有个 Set Character Encoding 过滤器。我们需要在 com.game.commons 包中新建 SetCharacterEncodingFilter 类来过滤编码，类的代码如下：

package  com.game.commons;

import  java.io.IOException;

import  javax.servlet.Filter;
import  javax.servlet.FilterChain;
import  javax.servlet.FilterConfig;
import  javax.servlet.ServletException;
import  javax.servlet.ServletRequest;
import  javax.servlet.ServletResponse;

public   class  SetCharacterEncodingFilter  implements  Filter  {
protected  String encoding  =   null ;
protected  FilterConfig filterConfig  =   null ;
protected   boolean  ignore  =   true ;

public   void  init(FilterConfig filterConfig)  throws  ServletException  {
this .filterConfig = filterConfig;
this .encoding = filterConfig.getInitParameter( " encoding " );
String value = filterConfig.getInitParameter( " ignore " );
if (value == null )
this .ignore = true ;
else   if (value.equalsIgnoreCase( " true " ))
this .ignore = true ;
else
this .ignore = false ;
}

public   void  doFilter(ServletRequest request, ServletResponse response, FilterChain chain)  throws  IOException, ServletException  {
//  TODO 自动生成方法存根
if  (ignore  ||  (request.getCharacterEncoding()  ==   null ))  {
String encoding  =  selectEncoding(request);
if  (encoding  !=   null )
request.setCharacterEncoding(encoding);
}
chain.doFilter(request, response);
}

public   void  destroy()  {
//  TODO 自动生成方法存根
this .encoding  =   null ;
this .filterConfig  =   null ;
}

protected  String selectEncoding(ServletRequest request)  {
return  ( this .encoding);
}
}

 

 

为了项目的测试运行，我们还需要配置 log4j.properties ，这个文件放在 src 根目录下。代码如下：

log4j.rootLogger=info,console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.SimpleLayout
log4j.logger.com.wehave=DEBUG
# log4j.logger.org.springframework=DEBUG
# SqlMap logging configuration
# log4j.logger.com.ibatis=DEBUG
# log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG
# log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG
# log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG
log4j.logger.java.sql.Connection=DEBUG
# log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
#log4j.logger.java.sql.ResultSet=DEBUG
#log4j.logger.javax.sql=DEBUG

 

这是一个简单的 log4j 配置方法，只是在后台打印出需要的数据。如果还有别的需求，可以参考这个文档：如何使用 Log4j ？

 

为了达到页面验证的目的，我们还需要使用到 struts 的验证框架。

在 struts-validator 中添加 validation.xml 。在这配置验证规则：

 

<! DOCTYPE form-validation PUBLIC
    "-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.0//EN"
    "http://jakarta.apache.org/commons/dtds/validator_1_0.dtd" >
    
< form-validation >
     < formset >
         < form  name ="productsForm" >
             < field  property ="gameNameCn"  depends ="required" >
                 < arg0  key ="errors.gameNameCn" />
             </ field >     
             < field  property ="gameNameEn"  depends ="required" >
                 < arg0  key ="errors.gameNameEn" />
             </ field >
             < field  property ="gameCapacity"  depends ="integer" >
                 < arg0  key ="errors.gameCapacity" />
             </ field >
             < field  property ="gamePrice"  depends ="float" >
                 < arg0  key ="errors.gamePrice" />
             </ field >
         </ form >     
     </ formset >
</ form-validation >

 

 

在同个目录下，添加 validator-rules.xml ，这个在 struts 开发包中有，只需要 copy 过来就可以用了。为了方便大家，我这里将里面配置代码粘贴出来：

<? xml version="1.0" encoding="ISO-8859-1"  ?>
<! DOCTYPE form-validation PUBLIC
          "-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.0//EN"
          "http://jakarta.apache.org/commons/dtds/validator_1_0.dtd" >
<!--
