SpringSide示例之HelloWorld

發布時間：2023/11/29 javascript 34 豆豆

生活随笔收集整理的這篇文章主要介紹了 SpringSide示例之HelloWorld 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

SpringSide是個什么東西呢？這么說吧，就是“采眾家之長”的一個一站式框架，它吸取了開源界許多優秀組件的精華部分，非常簡約的一個東西，具體就不多介紹了，自己可以參考官方文檔。

下面來看看運用這個框架實現一個簡單的用戶管理究竟有多么容易。

先來看表現層：

新增或修改用戶頁面：

<%@?page?contentType="text/html;charset=UTF-8"?%>
<%@?include?file="/commons/taglibs.jsp"?%>
<html>
<head>
????<%@?include?file="/commons/meta.jsp"?%>
????<title>User?Manage</title>
</head>

<body>
<div?id="page">
????<div?id="header">
????????<h1>Helloworld?Sample</h1>
????</div>
????<%@?include?file="/commons/messages.jsp"?%>
????<div?id="content">
????????<h1>User?Infomation?Manage</h1>
????????<html:form?action="/user.do"?focus="name"?styleClass="form"?onsubmit="return?validateUserForm(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>
</div>
<html:javascript?formName="userForm"?staticJavascript="false"?dynamicJavascript="true"?cdata="false"/>
<script?type="text/javascript"?src="${ctx}/scripts/validator.jsp"></script>
<%@?include?file="/commons/footer.jsp"?%>
</body>
</html>

用戶列表頁面：

<%@?page?contentType="text/html;charset=UTF-8"?%>
<%@?include?file="/commons/taglibs.jsp"?%>
<html>
<head>
????<%@?include?file="/commons/meta.jsp"?%>
????<link?href="${ctx}/widgets/extremecomponents/extremecomponents.css"?type="text/css"?rel="stylesheet">
????<title>User?Manage</title>
</head>

<body>
<div?id="page">
????<div?id="header">
????????<h1>Helloworld?Sample</h1>
????</div>

????<div?id="content">
????????<h1>User?List</h1>
????????<%@?include?file="/commons/messages.jsp"?%>
????????<ec:table?items="users"?var="user"
??????????????????action="${ctx}/user.do">
????????????<ec:exportXls?fileName="UserList.xls"?tooltip="Export?Excel"/>
????????????<ec:row>
????????????????<ec:column?property="rowcount"?cell="rowCount"?sortable="false"?title="No."?width="60"/>
????????????????<ec:column?property="id"?title="ID"?width="60"/>
????????????????<ec:column?property="name"?title="Name"?width="120"/>
????????????????<ec:column?property="email"?title="Email"?width="120"/>
????????????????<ec:column?property="descn"?title="Description"?viewsDenied="html"/>
????????????????<ec:column?property="null"?title="Edit"?width="40"?sortable="false"?viewsAllowed="html">
????????????????????<a?href="user.do?method=edit&id=${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>
</div>
<%@?include?file="/commons/footer.jsp"?%>
</body>
</html>

對應的控制器類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;

/**?*//**
?*?用戶管理Controller.
?*?<p/>
?*?繼承于StrutsEntityAction，不需編碼就擁有默認的對User對象的CRUD響應函數.?如果想了解不繼承于EntityAction,自行編寫CRUD的寫法,?參考{@link?UserActionNativeVersion}.
?*
?*?@author?calvin
?*?@see?org.springside.core.web.StrutsEntityAction
?*?@see?org.springside.core.web.StrutsAction
?*?@see?UserActionNativeVersion
?*/
public?class?UserAction?extends?StrutsEntityAction<User,?UserManager>?{

????@SuppressWarnings("unused")
????private?UserManager?userManager;

????public?void?setUserManager(UserManager?userManager)?{
????????this.userManager?=?userManager;
????}
}

然后是業務邏輯層，

package?org.springside.helloworld.service;

import?org.springside.core.dao.HibernateEntityDao;
import?org.springside.helloworld.model.User;

/**?*//**
?*?用戶管理業務類.
?*?<p/>
?*?繼承于HibernateEntityDao,不需任何代碼即擁有默認的對User對象的CRUD函數.?如果想了解不繼承于EntityDao,自行編寫CRUD的寫法,?參考{@link?UserManagerNativeVersion}.
?*
?*?@author?calvin
?*?@see?HibernateEntityDao
?*?@see?org.springside.core.dao.HibernateGenericDao
?*?@see?UserManagerNativeVersion
?*/
public?class?UserManager?extends?HibernateEntityDao<User>?{
????//?.CRUD以外的其它商業方法
}

然后是模型層

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;

/**?*//**
?*?用戶.帶jpa?annotation簡版配置.
?*
?*?@author?calvin
?*?@author?schweigen
?*/
?//同USERS表映射
@Entity
@Table(name?=?"USERS")
public?class?User?
{
????private?Integer?id;//用戶id?

????private?String?name;//用戶名

????private?String?email;//e-mail

????private?String?descn;//自我介紹

????//主鍵自動生成,其他,其余屬性全部與數據庫中的列默認映射。
????@Id
????@GeneratedValue(strategy?=?GenerationType.AUTO)
????public?Integer?getId()?{
????????return?id;
????}

????public?void?setId(Integer?id)?{
????????this.id?=?id;
????}

????public?String?getName()?{
????????return?name;
????}

????public?void?setName(String?name)?{
????????this.name?=?name;
????}

????public?String?getEmail()?{
????????return?email;
????}

????public?void?setEmail(String?email)?{
????????this.email?=?email;
????}

????public?String?getDescn()?{
????????return?descn;
????}

????public?void?setDescn(String?descn)?{
????????this.descn?=?descn;
????}
}

那么代碼部分就這些了，可以看到不需要我們自己去寫重復的CRUD代碼，僅僅從一些特定的基類繼承下來就可以了，而Jdk新加入的泛型技術的運用更是如虎添翼。那么對于配置文件部分，我個人感覺比以前好像更加復雜了呢，也許是還不習慣吧。。。
