說在前面的話：
??????書接上回（間隔很久了，抱歉，各位看官！），Charpter1介紹了Portlet的一些基礎知識，本章從一個實例的開發，介紹如何應用Spring Portlet MVC開發自己的Portlet。

Charpter2 Spring Portlet MVC實例開發

實例介紹：

實現一個簡單的用戶注冊詳細信息的編輯與查看功能。

開發環境：

Dev Tool: Eclipse 3.2

Web Server: Tomcat 5.5

Framework: Spring 1.2.8 +?Spring Portlet MVC + Hibernate 3.2.0.GA

Portal Server:?Liferay Portal 4.3.0

Database: Oracle 9i

開發過程：

0) 建立工程結構

整個工程

source包下的結構：

web包下的結構：

1) 創建Model
創建注冊信息的Model實體，如下代碼：

/**

?*?WsspUser?申報用戶信息

?*?@author?Allen

?*/

@SuppressWarnings("serial")

@Entity

@Table(name?=?"MY_USER")

@Cache(usage?=?CacheConcurrencyStrategy.READ_WRITE)

public?class?WsspUser?extends?BaseNameObject?{

????/**?public?attrrbutes?**/

????@Column(length?=?100)

????private?String?userType;//標識會員類型?企業會員:E?政府會員:G?個人會員:P?社團會員:C?其他會員:O

????

????@Column(length?=?4)

????private?int?personActive;?//用戶狀態：1?啟用，0?停用

????

????@Column(length?=?4)

????private?int?actAsAgent;?//是否為代辦：1?是，0?不是

????

????private?String?surrogateId;?//代辦人員編號

????private?String?wsspPersonId;?//用戶唯一標識，存放Liferay生成的用戶ID

????

????private?String?initials;?//昵稱

????

????@Temporal(TemporalType.TIMESTAMP)

????private?java.util.Date?createTime;?//創建日期

????

????@Temporal(TemporalType.TIMESTAMP)

????private?java.util.Date?modifyTime;//修改日期

????

????private?String?createBy;//創建人

????private?String?modifyBy;//修改人

????

????/**?personal?attrrbutes?**/

????private?String?trueName;?//用戶真實姓名

????

????@Column(length?=?100)

????private?String?sex;?//性別

????

????@Temporal(TemporalType.TIMESTAMP)

????private?java.util.Date?birthday;?//出生年月日

????

????/**?enterprise?attrrbutes?**/

????@Column(length?=?10)

????private?int?capital;?//注冊資金(萬元)

????

????private?String?businessCategory;?//經營范圍

????private?String?legalRepresentative;?//法人代表

????private?String?businessLicense;?//工商營業執照號、社團登記證號碼

????

????@Column(length?=?100)

????private?String?identityType;?//標識證件類別?身份證:I、軍官證:M、護照:P、其他證件:O

???

????private?String?identityCard;?//有效證件號、法人有效證件號

????private?String?address;?//住址、注冊地址、辦公地址

????private?String?postalCode;?//郵政編碼

????private?String?telephone;?//聯系電話、單位聯系電話

????private?String?mobile;?//手機、單位聯系人手機

????private?String?fax;?//單位傳真、個人傳真

????private?String?mail;?//電子郵件

????private?String?url;?//網址

????????.......

2) 創建持久層和Service層

???包括持久層和服務層的類和配置文件都很簡單，不做表述了。我這里是將這兩層合并了。

3) 創建表現層Controller

???這里以查看動作的Controller為例

/**

?*?UserRegViewController

?*?@author?Allen

?*?@time?10:09:34?AM?Mar?3,?2008

?*/

public?class?UserRegViewController?extends?BaseController?{

????private?UserRegisterService?userRegisterService;

????

????public?void?setUserRegisterService(UserRegisterService?userRegisterService)?{

????????this.userRegisterService?=?userRegisterService;

????}

????

????@Override

????protected?void?doFillData(RenderRequest?req,?Map?model)?{

????????//0)?get?user?id?in?the?portlet

????????String?uid?=?req.getRemoteUser();

????????//1)?find?the?user's?properties?in?gea

????????WsspUser?wsspUser;

????????if?(null?==?uid)?uid?=?"";

????????String?hql?=?"FROM?WsspUser?AS?u?WHERE?u.wsspPersonId?=??";

????????wsspUser?=?userRegisterService.findForUnique(hql,?new?Object[]{uid});

????????//2)?if?cannot?find?the?user?by?liferay?user?id,?it?means?we?haven't?set?the?properties?

????????if?(null?==?wsspUser)?{

????????????wsspUser?=?new?WsspUser();

????????????wsspUser.setWsspPersonId(uid);

????????}

????????model.put("wsspUser",?wsspUser);

????}

????

}

4) 配置 Spring Portlet MVC

???創建userregister.xml配置文件

<?xml?version="1.0"?encoding="UTF-8"??>

<!DOCTYPE?beans?PUBLIC?"-//SPRING//DTD?BEAN//EN"?"../../dtd/spring-beans.dtd">

<beans>

????<bean?id="userRegControllerTemplate"?abstract="true">

????????<property?name="userRegisterService"?ref="userRegisterService"?/>

????</bean>

????

????

????<bean?id="userRegViewController"?class="net.allen.portlet.userregister.controller.UserRegViewController"?parent="userRegControllerTemplate">

????????<property?name="viewName"?value="userregister/userView"?/>

????</bean>

????

????<bean?id="userRegEditController"?class="net.allen.portlet.userregister.controller.UserRegEditController"?parent="userRegControllerTemplate">

????????<property?name="sessionForm"?value="true"/>

????????<property?name="commandName"?value="wsspUser"?/>

????????<property?name="commandClass"?value="net.allen.portlet.userregister.domain.WsspUser"?/>

????????<property?name="formView"?value="userregister/userEdit"?/>

????</bean>

????

????

????<bean?id="parameterMappingInterceptor"?class="org.springframework.web.portlet.handler.ParameterMappingInterceptor"/>

????<bean?id="portletModeParameterHandlerMapping"?class="org.springframework.web.portlet.handler.PortletModeParameterHandlerMapping">

????????<property?name="order"?value="10"/>

????????<property?name="interceptors">

????????????<list>

????????????????<ref?bean="parameterMappingInterceptor"/>

????????????????<ref?bean="openSessionInViewInterceptor"/>

????????????</list>

????????</property>

????????<property?name="portletModeParameterMap">

????????????<map>

????????????????<entry?key="view">

????????????????????<map>

????????????????????????<entry?key="viewUser"><ref?bean="userRegViewController"/></entry>

????????????????????????<entry?key="editUser"><ref?bean="userRegEditController"/></entry>

????????????????????</map>

????????????????</entry>

????????????</map>

????????</property>

????</bean>

????<bean?id="portletModeHandlerMapping"?class="org.springframework.web.portlet.handler.PortletModeHandlerMapping">

????????<property?name="interceptors">

????????????<ref?bean="openSessionInViewInterceptor"/>

????????</property>

????????<property?name="portletModeMap">

????????????<map>

????????????????<entry?key="view"><ref?bean="userRegViewController"/></entry>

????????????</map>

????????</property>

????</bean>

????

????<bean?id="defaultExceptionHandler"?parent="defaultExceptionHandlerTemplate"/>

????

</beans>

5) 創建View層（采用JSP）

???????采用JSP處理表現層頁面，其中采用Liferay的portlet標簽做參數傳遞或觸發動作，不在這里贅述了。下面的一段示例顯示了EDIT和HOME的鏈接操作。 - EDIT - HOME -

???...

<p?style="text-align:center;">-?

????<a?href="<portlet:renderURL>

????????????<portlet:param?name="action"?value="editUser"/>

????????????<portlet:param?name="ID"?value="${model.wsspUser.id}"/>

????????????<portlet:param?name="uid"?value="${model.wsspUser.wsspPersonId}"/>

????????</portlet:renderURL>"><spring:message?code="button.edit"/></a>?-?

????<a?href="<portlet:renderURL?portletMode="view"/>"><spring:message?code="button.home"/></a>

-</p>
???...

6) 配置Liferay Portlet

·在portlet.xml中添加

<portlet>
????????<portlet-name>userregister</portlet-name>
????????<display-name>My?User?Register</display-name>
????????<portlet-class>org.springframework.web.portlet.DispatcherPortlet</portlet-class>
????????<init-param>
????????????<name>contextConfigLocation</name>
????????????<value>classpath*:/config/spring/portlet/userregister.xml</value>
????????</init-param>
????????<supports>
????????????<mime-type>text/html</mime-type>
????????????<portlet-mode>view</portlet-mode>
????????</supports>
????????<portlet-info>
????????????<title>my?user?register</title>
????????</portlet-info>??????
????</portlet>

·在liferay-portlet.xml中添加

<portlet>
????????<portlet-name>userregister</portlet-name>
????????<restore-current-view>false</restore-current-view>
????</portlet>

·在liferay-display.xml中添加（我將開發的Portlet添加到測試目錄中）

<category?name="category.test">
????????<portlet?id="userregister"?/>
????</category>

·在web.xml中添加


????<listener>
????????<listener-class>com.liferay.portal.kernel.servlet.PortletContextListener</listener-class>
????</listener>


<servlet>
????????<servlet-name>liferayServlet</servlet-name>
????????<servlet-class>com.liferay.portal.kernel.servlet.PortletServlet</servlet-class>
????????<init-param>
????????????<param-name>portlet-class</param-name>
????????????<param-value>org.springframework.web.portlet.DispatcherPortlet</param-value>
????????</init-param>
????????<load-on-startup>0</load-on-startup>
????</servlet>

<servlet-mapping>
????????<servlet-name>liferayServlet</servlet-name>
????????<url-pattern>/userregister/*</url-pattern>
????</servlet-mapping>


<taglib>
????????<taglib-uri>http://java.sun.com/portlet</taglib-uri>
????????<taglib-location>/WEB-INF/tld/liferay-portlet.tld</taglib-location>
????</taglib>
????<taglib>
????????<taglib-uri>http://liferay.com/tld/portlet</taglib-uri>
????????<taglib-location>/WEB-INF/tld/liferay-portlet-ext.tld</taglib-location>
????</taglib>????

??????經過這六步的操作，一個簡單的Portlet就完成了，現在可以部署Portlet應用到服務器中，在Liferay里體驗自己開發的Portlet了，是不是很簡單呢，呵呵。

生存或毀滅，這是個必答之問題：是否應默默的忍受坎苛命運之無情打擊，還是應與深如大海之無涯苦難奮然為敵，并將其克服。此二抉擇，究竟是哪個較崇高？
