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;
/** */ /**

*/
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 " );
}
/** */ /**

}
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" >

</ action >

</ 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 name ="productsService" >
< ref bean ="productsService" />
</ property >
</ bean >
< bean name ="/deleteProduct" class ="com.game.products.web.actions.ProductsAction" singleton ="false" >
< property name ="productsService" >
< ref bean ="productsService" />
</ property >
</ bean >
< bean name ="/addProductPage" class ="com.game.products.web.actions.ProductsAction" singleton ="false" >
< property name ="productsService" >
< ref bean ="productsService" />
</ property >
</ bean >
< bean name ="/addProduct" class ="com.game.products.web.actions.ProductsAction" singleton ="false" >
< property name ="productsService" >
< ref bean ="productsService" />
</ property >
</ bean >
< bean name ="/updateProduct" class ="com.game.products.web.actions.ProductsAction" singleton ="false" >
< property name ="productsService" >

</ property >
</ bean >

< property name ="productsService" >
< ref bean ="productsService" />
</ property >
< property name ="pagerService" >
< ref bean ="pagerService" />
</ property >
</ bean >
< bean name ="/queryProducts" class ="com.game.products.web.actions.ProductsAction" singleton ="false" >
< property name ="productsService" >
< ref bean ="productsService" />
</ property >
< property name ="pagerService" >
< ref bean ="pagerService" />
</ property >
</ bean >
接着编写 web.xml ，代码如下：
<? xml version="1.0" encoding="GB2312" ?>
<! DOCTYPE web-app

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" >
<!--
This file contains the default Struts Validator pluggable validator
definitions. It should be placed somewhere under /WEB-INF and
referenced in the struts-config.xml under the plug-in element
for the ValidatorPlugIn.
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
<set-property property="pathnames" value="/WEB-INF/validator-rules.xml,
/WEB-INF/validation.xml"/>
</plug-in>
These are the default error messages associated with
each validator defined in this file. They should be
added to your projects ApplicationResources.properties
file or you can associate new ones by modifying the
pluggable validators msg attributes in this file.
# Struts Validator Error Messages
errors.required={0} is required.
errors.minlength={0} can not be less than {1} characters.
errors.maxlength={0} can not be greater than {1} characters.
errors.invalid={0} is invalid.
errors.byte={0} must be a byte.
errors.short={0} must be a short.
errors.integer={0} must be an integer.
errors.long={0} must be a long.
errors.float={0} must be a float.
errors.double={0} must be a double.
errors.date={0} is not a date.
errors.range={0} is not in the range {1} through {2}.
errors.creditcard={0} is an invalid credit card number.
errors.email={0} is an invalid e-mail address.

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;

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 name ="productsService" >
< ref bean ="productsService" />
</ property >
</ bean >
< bean name ="/deleteProduct" class ="com.game.products.web.actions.ProductsAction" singleton ="false" >
< property name ="productsService" >
< ref bean ="productsService" />
</ property >
</ bean >
< bean name ="/addProductPage" class ="com.game.products.web.actions.ProductsAction" singleton ="false" >
< property name ="productsService" >
< ref bean ="productsService" />
</ property >
</ bean >
< bean name ="/addProduct" class ="com.game.products.web.actions.ProductsAction" singleton ="false" >
< property name ="productsService" >
< ref bean ="productsService" />
</ property >
</ bean >
< bean name ="/updateProduct" class ="com.game.products.web.actions.ProductsAction" singleton ="false" >
< property name ="productsService" >
< ref bean ="productsService" />
</ property >
</ bean >
< bean name ="/returnProduct" class ="com.game.products.web.actions.ProductsAction" singleton ="false" >
< property name ="productsService" >
< ref bean ="productsService" />
</ property >
< property name ="pagerService" >

</ bean >
< bean name ="/queryProducts" class ="com.game.products.web.actions.ProductsAction" singleton ="false" >
< property name ="productsService" >
< ref bean ="productsService" />
</ property >
< property name ="pagerService" >
< ref bean ="pagerService" />
</ property >
</ bean >
接着编写 web.xml ，代码如下：
<? xml version="1.0" encoding="GB2312" ?>

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" >
<!--
This file contains the default Struts Validator pluggable validator
definitions. It should be placed somewhere under /WEB-INF and
referenced in the struts-config.xml under the plug-in element
for the ValidatorPlugIn.
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
<set-property property="pathnames" value="/WEB-INF/validator-rules.xml,
/WEB-INF/validation.xml"/>
</plug-in>
These are the default error messages associated with
each validator defined in this file. They should be
added to your projects ApplicationResources.properties
file or you can associate new ones by modifying the
pluggable validators msg attributes in this file.
# Struts Validator Error Messages
errors.required={0} is required.
errors.minlength={0} can not be less than {1} characters.
errors.maxlength={0} can not be greater than {1} characters.
errors.invalid={0} is invalid.
errors.byte={0} must be a byte.
