liferay spring mvc的实现

来源：互联网发布：sql sequence 编辑：程序博客网时间：2024/05/22 02:14

1 首先推荐一本liferay的书

Portlet In Action,

本例是按照这本书进行配置的，原文在 Getting started with Spring Portlet MVC中进行了介绍,原理里面讲解的很清楚

2 首先需要导入的包

3 我项目存在一个插件类型为 Protlet的名称为MyFirstPortlet的portlet 工程，在着项目中新建一个名为myliferayspringmvc的Protlet,用eclipse ide自动生成代码

4 在docroot/WEB-INF/src单机右键新建一个Package并命名为com.springMVC

5在com.springMVC右键单击，新建一个class，命名为SpringPortlet.java，代码如下

package com.springMVC;

import java.util.HashMap;
import java.util.Map;
import javax.portlet.ActionRequest;
import javax.portlet.ActionResponse;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;

import org.springframework.web.portlet.ModelAndView;
import org.springframework.web.portlet.mvc.Controller;

public class SpringPortlet implements Controller{

@Override
public void handleActionRequest(ActionRequest actionRequest, ActionResponse actionResponse)
throws Exception {

}

@Override
public ModelAndView handleRenderRequest(RenderRequest renderRequest,
RenderResponse renderResponse) throws Exception {
Map<String,Object> model = new HashMap<String,Object>();
System.out.println("运行到了这里哦");
model.put("helloWorldMessage", "Hello World");
return new ModelAndView("view",model); //ModelAndView("view",model) //这里面的view 对应了 /html/myliferayspringmvc/view.jsp
}

}

6 在html/myliferayspringmvc/view.jsp代码如下

<%@page import="com.liferay.portal.util.PortalUtil"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page language="java" contentType="text/html; charset=UTF-8"%>
<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>
<portlet:defineObjects />

<c:out value="${helloWorldMessage}"></c:out>

7 配置好Portlet.xml

8 配置好myliferayspringmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">


<beans>

<bean id="springPortlet" class="com.springMVC.SpringPortlet">
</bean>

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

<property name="portletModeMap">
<map>
<entry key="view">
<ref bean="springPortlet"/>
</entry>

</map>
</property>

</bean>



<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/html/myliferayspringmvc/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
</beans>

9 配置好 web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<servlet>
<servlet-name>ViewRendererServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.ViewRendererServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ViewRendererServlet</servlet-name>
<url-pattern>/WEB-INF/servlet/view</url-pattern>
</servlet-mapping>

</web-app>

10 到这一步就就算搭建好了一个简单的liferay spring mvc架子了，至于原理请参考第1步推荐的书籍 Portlet In Action,中去查看
