1、在MyEclipse下建立一個(gè)web應(yīng)用
2、導(dǎo)包
從解壓后的 spring 文件夾中尋找 jstl.jar、standard.jar、spring.jar、spring-webmvc.jar、spring-webmvc-portlet.jar、commons-logging.jar拷貝到
WEB-INF/lib 目錄下。
3、編輯web.xml
在web.xml文件中添加以下代碼：
|
<!-- 設(shè)定Spring的根上下文 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<!-- 設(shè)定ViewRendererServlet -->
<servlet>
<servlet-name>ViewRendererServlet</servlet-name>
<servlet-class>
org.springframework.web.servlet.ViewRendererServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>ViewRendererServlet</servlet-name>
<url-pattern>/WEB-INF/servlet/view</url-pattern>
</servlet-mapping>
<!-- 設(shè)定加載一個(gè)Portlet的Servlet, 該配置為Pluto所需-->
<servlet>
<servlet-name>SpringTestPortlet1</servlet-name>
<servlet-class>
org.apache.pluto.container.driver.PortletServlet
</servlet-class>
<init-param>
<param-name>portlet-name</param-name>
<param-value>SpringTestPortlet1</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>SpringTestPortlet1</servlet-name>
<url-pattern>/PlutoInvoker/SpringTestPortlet1</url-pattern>
</servlet-mapping>
<jsp-config>
<taglib>
<taglib-uri>http://portals.apache.org/pluto</taglib-uri>
<taglib-location>/WEB-INF/tld/pluto.tld</taglib-location>
</taglib>
</jsp-config>
|
4、編輯Portlet.xml文件
|
<?xml version="1.0"
encoding="UTF-8"?>
<portlet-app
xmlns="http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd"
version="2.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd
http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd">
<portlet>
<portlet-name>SpringTestPortlet1</portlet-name>
<display-name>SpringTestPortlet1</display-name>
<portlet-class>
org.springframework.web.portlet.DispatcherPortlet
</portlet-class>
<init-param>
<name>contextConfigLocation</name>
<value>/WEB-INF/springtest-portlet1.xml</value>
</init-param>
<supports>
<mime-type>text/html</mime-type>
<portlet-mode>view</portlet-mode>
<portlet-mode>edit</portlet-mode>
<portlet-mode>help</portlet-mode>
</supports>
<portlet-info>
<title>SpringTestPortlet1</title>
</portlet-info>
</portlet>
</portlet-app>
|
5、編寫相應(yīng)的Java
POJO類、jsp文件、Spring配置文件
Pojo類在此不再敷述，jsp文件中的開始標(biāo)簽部分如下：
|
<%@ page import="javax.portlet.*"
contentType="text/html; charset=utf-8" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="portlet"
uri="http://java.sun.com/portlet"%>
<%@ taglib prefix="spring"
uri="http://www.springframework.org/tags"%>
<%@ taglib prefix="form"
uri="http://www.springframework.org/tags/form"%>
<portlet:actionURL var="actionURL"
/>
|
在 WEB-INF 下新建
applicationContext.xml 文件，內(nèi)容如下：
|
<?xml version="1.0"
encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<!--
Default View Resolver -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView"
/>
<property name="prefix"
value="/WEB-INF/jsp/" />
<property name="suffix"
value=".jsp" />
</bean>
<!--
Default ExceptionHandler -->
<bean id="defaultExceptionHandler"
class="org.springframework.web.portlet.handler.SimpleMappingExceptionResolver">
<property name="order"
value="10" />
<property name="defaultErrorView"
value="error" />
<property name="exceptionMappings">
<props>
<prop key="javax.portlet.UnavailableException">
unavailable
</prop>
<prop key="java.lang.Exception">error</prop>
</props>
</property>
</bean>
</beans>
|
該配置文件中，定義了兩個(gè) Bean。其中第一個(gè) Bean 定義了視圖的默認(rèn)解析方式，使用 JSP 作為視圖（View)，到 /WEB-INF/jsp/ 目錄下尋找 Jsp 文件，并且視圖名稱為 jsp 文件名的前綴。
在第二個(gè) Bean 中，定義了異常處理方式。如果發(fā)生
javax.portlet.UnavailableException 異常，則呈現(xiàn) unavailable 視圖，即 unavailable.jsp 文件；如果發(fā)生其它的 java.lang.Exception 異常，則呈現(xiàn) error 視圖，即 error.jsp 文件。
在 WEB-INF 下新建 PortletSpringTestPortlet1 的 Spring 上下文配置文件 springtest-portlet1.xml 如下：
|
<?xml version="1.0"
encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean
class="org.springframework.web.portlet.handler.PortletModeHandlerMapping">
<property name="portletModeMap">
<map>
<entry key="view"
value-ref="viewController" />
</map>
</property>
</bean>
<bean id="viewController"
class="org.springframework.web.portlet.mvc.SimpleFormController">
<property name="commandClass"
value="springportal.command.AddressBook"
/>
<property name="commandName"
value="addressBook" />
<property name="formView"
value="addressInput" />
<property name="successView"
value="result" />
</bean>
</beans>
|
該上下文根據(jù) Portlet 模式分配控制器，由 Bean 定義可知，僅僅定義了 view 模式的控制器，edit 和 help 模式都沒有進(jìn)行定義。
在 View 模式的控制器 viewController 中，定義了 commandClass 和 commandName 來保存用戶輸入的表單數(shù)據(jù)，addressInput 視圖（addressInput.jsp）為輸入表單，result 視圖（result.jsp）呈現(xiàn)表單提交結(jié)果。
6、遇到的問題
java.lang.ClassCastException:org.springframework.web.servlet.support.JstlUtils$SpringLocalizationContext
|
I had
the same issue with Pluto current bundle distribution 1.1.6.
The ClassCastException is actually from Pluto's default theme jsp. It's
trying to cast a
org/springframework/web/servlet/support/JstlUtils$SpringLocalizationContext
into a java/lang/String . This is due to that the JSTL implementation doesn't
recognize SpringLocalizationContext as a LocalizationContext instance though
SpringLocalizationContext surely implements the interface. The root cause is
that two classes are loaded from different classloader thus the instanceof
check failed.
Solution: move the jstl-1.0.6.jar and
standard-1.0.6.jar under pluto-1.1.6"webapps"pluto"WEB-INF"lib into
pluto-1.1.6"shared"lib
Note: do not include these 2 jar files in your
portlet application (war file).

解決方法：將pluto-2.0"webapps"pluto"WEB-INF"lib下的jstl.jar和standard.jar移動(dòng)到pluto-2.0"lib目錄下
