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;

/**

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 " );

Products pd = productsService.getProduct(gameId);

req.setAttribute( " pd " , pd);

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" >

< action path ="/queryProducts" type ="org.springframework.web.struts.DelegatingActionProxy" parameter ="method" scope ="request" validate ="false" >

< forward name ="all" path ="/products/products.jsp" />

action >

< message-resources parameter ="com.game.resources.ApplicationResourcesProducts" />

< 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：

< 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 name ="productsService" >

< ref bean ="productsService" />

property >

< property name ="pagerService" >

< ref bean ="pagerService" />

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" ?>

}

alert(fields.join('\n'));

}

导读：许多企业都坚信，即便内部分配存在一些不合理，但也不会背离“多劳多得”的原则。可“智猪博弈”结果说明，由于工作相互牵扯，业绩相互掣肘，最后的分配结果很可能“多劳不多得、少劳不少得”。智猪博弈：假设猪圈里有两头猪，一头大猪，一头小猪。猪圈很长，一头有一踏板，另一头是饲料的出口和食槽。猪每踩一下踏板，另一边就会有相当于10份的猪食进槽，但是不论谁跑去踩踏板，都会首先消耗2个单位的体力成本。假设小猪

Java集合对象和数组对象的转换 dyy_gusi java集合
在开发中，我们经常需要将集合对象（List，Set）转换为数组对象，或者将数组对象转换为集合对象。Java提供了相互转换的工具，但是我们使用的时候需要注意，不能乱用滥用。 1、数组对象转换为集合对象最暴力的方式是new一个集合对象，然后遍历数组，依次将数组中的元素放入到新的集合中，但是这样做显然过
nginx同一主机部署多个应用 geeksun nginx

ubuntu添加admin权限的用户账号 hongtoushizi ubuntu useradd
ubuntu创建账号的方式通常用到两种：useradd 和adduser . 本人尝试了useradd方法，步骤如下： 1:useradd 使用useradd时，如果后面不加任何参数的话，如：sudo useradd sysadm 创建出来的用户将是默认的三无用户：无home directory ,无密码,无系统shell。顾应该如下操作：
第五章常用Lua开发库2-JSON库、编码转换、字符串处理 jinnianshilongnian nginx lua
JSON库在进行数据传输时JSON格式目前应用广泛，因此从Lua对象与JSON字符串之间相互转换是一个非常常见的功能；目前Lua也有几个JSON库，本人用过cjson、dkjson。其中cjson的语法严格（比如unicode \u0020\u7eaf），要求符合规范否则会解析失败（如\u002），而dkjson相对宽松，当然也可以通过修改cjson的源码来完成

[转]SQLite的工具类 ---- 通过反射把Cursor封装到VO对象 ctfzh VO android sqlite 反射 Cursor
在写DAO层时，觉得从Cursor里一个一个的取出字段值再装到VO(值对象)里太麻烦了，就写了一个工具类，用到了反射，可以把查询记录的值装到对应的VO里，也可以生成该VO的List。使用时需要注意：考虑到Android的性能问题，VO没有使用Setter和Getter，而是直接用public的属性。表中的字段名需要和VO的属性名一样，要是不一样就得在查询的SQL中
