SpringSide是个什么东西呢？这么说吧，就是“采众家之长”的一个一站式框架，它吸取了开源界许多优秀组件的精华部分，非常简约的一个东西，具体就不多介绍了，自己可以参考官方文档。

下面来看看运用这个框架实现一个简单的用户管理究竟有多么容易。

先来看表现层：

新增或修改用户页面：

@pagecontentType="text/html;charset=UTF-8" %>

@includefile="/commons/taglibs.jsp" %>

< html >

< head >

@includefile="/commons/meta.jsp" %>

< title > UserManage </ title >

</ head >

< body >

< div id ="page" >

< div id ="header" >

< h1 > HelloworldSample </ h1 >

</ div >

@includefile="/commons/messages.jsp" %>

< div id ="content" >

< h1 > UserInfomationManage </ h1 >

< html:form action ="/user.do" focus ="name" styleClass ="form" onsubmit ="returnvalidateUserForm(this)" >

< input type ="hidden" name ="method" value ="save" />

< html:hidden property ="id" />

< table >

< tr >

< td >< label > Name </ label ></ td >

< td >

< html:text property ="name" styleClass ="text" />

< span class ="req" > * </ span >

< span class ="fieldError" >< html:errors property ="name" /></ span >

</ td >

</ tr >

< tr >

< td >< label > EMail </ label ></ td >

< td >

< html:text property ="email" styleClass ="text" />

</ td >

</ tr >

< tr >

< td >< label > Remark </ label ></ td >

< td >

< html:textarea property ="descn" rows ="10" cols ="40" />

</ td >

</ tr >

</ table >

< div >

< html:submit property ="saveBtn" styleClass ="button" > Save </ html:submit >

< html:cancel styleClass ="button" > Cancel </ html:cancel >

</ div >

</ html:form >

</ div >

< html:javascript formName ="userForm" staticJavascript ="false" dynamicJavascript ="true" cdata ="false" />

< script type ="text/javascript" src ="${ctx}/scripts/validator.jsp" ></ script >

@includefile="/commons/footer.jsp" %>

</ body >

</ html >

用户列表页面：

@pagecontentType="text/html;charset=UTF-8" %>

@includefile="/commons/taglibs.jsp" %>

< html >

< head >

@includefile="/commons/meta.jsp" %>

< link href ="${ctx}/widgets/extremecomponents/extremecomponents.css" type ="text/css" rel ="stylesheet" >

< title > UserManage </ title >

</ head >

< body >

< div id ="page" >

< div id ="header" >

< h1 > HelloworldSample </ h1 >

</ div >

< div id ="content" >

< h1 > UserList </ h1 >

@includefile="/commons/messages.jsp" %>

< ec:table items ="users" var ="user"

action ="${ctx}/user.do" >

< ec:exportXls fileName ="UserList.xls" tooltip ="ExportExcel" />

< ec:row >

< ec:column property ="rowcount" cell ="rowCount" sortable ="false" title ="No." width ="60" />

< ec:column property ="id" title ="ID" width ="60" />

< ec:column property ="name" title ="Name" width ="120" />

< ec:column property ="email" title ="Email" width ="120" />

< ec:column property ="descn" title ="Description" viewsDenied ="html" />

< ec:column property ="null" title ="Edit" width ="40" sortable ="false" viewsAllowed ="html" >

< a href ="user.do?method=edit&id=${user.id}" > Edit </ a >

</ ec:column >

< ec:column property ="null" title ="Remove" width ="40" sortable ="false" viewsAllowed ="html" >

< a href ="user.do?method=delete&id=${user.id}" > Delete </ a >

</ ec:column >

</ ec:row >

</ ec:table >

</ div >

< div >

< button id ="addbtn" onclick ="location.href='user.do?method=create'" > Add </ button >

</ div >

@includefile="/commons/footer.jsp" %>

</ body >

</ html >

对应的控制器类UserAction.java:

package org.springside.helloworld.web;

import org.springside.core.web.StrutsEntityAction;

import org.springside.helloworld.model.User;

import org.springside.helloworld.service.UserManager;

/***/ /**

*用户管理Controller.

*<p/>

*继承于StrutsEntityAction，不需编码就拥有默认的对User对象的CRUD响应函数.如果想了解不继承于EntityAction,自行编写CRUD的写法,参考{@linkUserActionNativeVersion}.

*@authorcalvin

*@seeorg.springside.core.web.StrutsEntityAction

*@seeorg.springside.core.web.StrutsAction

*@seeUserActionNativeVersion

public class UserAction extends StrutsEntityAction < User,UserManager >

{

@SuppressWarnings("unused")

privateUserManageruserManager;

publicvoidsetUserManager(UserManageruserManager)

{

this.userManager=userManager;

}

然后是业务逻辑层，

package org.springside.helloworld.service;

import org.springside.core.dao.HibernateEntityDao;

import org.springside.helloworld.model.User;

/***/ /**

*用户管理业务类.

*<p/>

*继承于HibernateEntityDao,不需任何代码即拥有默认的对User对象的CRUD函数.如果想了解不继承于EntityDao,自行编写CRUD的写法,参考{@linkUserManagerNativeVersion}.

*@authorcalvin

*@seeHibernateEntityDao

*@seeorg.springside.core.dao.HibernateGenericDao

*@seeUserManagerNativeVersion

public class UserManager extends HibernateEntityDao < User >

{

.CRUD以外的其它商业方法

}

然后是模型层

package org.springside.helloworld.model;

import javax.persistence.Entity;

import javax.persistence.GeneratedValue;

import javax.persistence.GenerationType;

import javax.persistence.Id;

import javax.persistence.Table;

/***/ /**

*用户.带jpaannotation简版配置.

*@authorcalvin

*@authorschweigen

// 同USERS表映射

@Entity

@Table(name = " USERS " )

public class User

{

privateIntegerid;//用户id

privateStringname;//用户名

privateStringemail;//e-mail

privateStringdescn;//自我介绍

//主键自动生成,其他,其余属性全部与数据库中的列默认映射。

@Id

@GeneratedValue(strategy=GenerationType.AUTO)

publicIntegergetId()

{

returnid;

}

publicvoidsetId(Integerid)

{

this.id=id;

}

publicStringgetName()

{

returnname;

}

publicvoidsetName(Stringname)

{

this.name=name;

}

publicStringgetEmail()

{

returnemail;

}

publicvoidsetEmail(Stringemail)

{

this.email=email;

}

publicStringgetDescn()

{

returndescn;

}

publicvoidsetDescn(Stringdescn)

{

this.descn=descn;

}

那么代码部分就这些了，可以看到不需要我们自己去写重复的CRUD代码，仅仅从一些特定的基类继承下来就可以了，而Jdk新加入的泛型技术的运用更是如虎添翼。那么对于配置文件部分，我个人感觉比以前好像更加复杂了呢，也许是还不习惯吧。。。
