portal demo

1、新建web工程testportal，向工程中添加portal2.0 jar包

2、创建portlet

package com.miiwill;

import java.io.IOException;

import javax.portlet.GenericPortlet;
import javax.portlet.PortletException;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;

public class Helloworld extends GenericPortlet {
    @Override
    protected void doView(RenderRequest request, RenderResponse response) 
                   throws PortletException, IOException {
        response.setContentType("text/html");
        response.getWriter().println("<h2>hello world,View Mode</h2>");
    }

    @Override  
    protected void doEdit(RenderRequest request, RenderResponse response)   
        throws PortletException, IOException {   
        response.setContentType("text/html");    
        response.getWriter().println("<h2>hello world,Edit Mode</h2>");   
    }   
}


3、修改web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app 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>
        <!--pluto通过servlet来知道哪个context是portlet，如果没有这个servlet，portlet就没法注册到pluto中-->
        <servlet-name>HelloWorldPortal</servlet-name>
        <!--在pluto1.0中是org.apache.pluto.core.PortletServlet-->        
        <servlet-class>org.apache.pluto.container.driver.PortletServlet</servlet-class>
        <!--portlet的名字必须和portlet.xml中portlet的名字一致-->
        <init-param>
            <param-name>portlet-name</param-name>
            <param-value>HelloWorldPortalDemo</param-value>
        </init-param>
        <!--唯一标识，每个portlet的标识应该都不同-->
        <init-param>
            <param-name>portlet-guid</param-name>
            <param-value>HelloWorldPortal.HelloWorldPortalDemo</param-value>
        </init-param>
        <!--这个参数是告诉pluto，portlet名字所对应的类是什么-->
        <init-param>
            <param-name>portlet-class</param-name>
            <param-value>com.miiwill.Helloworld</param-value>
        </init-param>
        <!--PortletServlet执行init时，根据charset参数获取字符集，
                               然后在执行响应时调用response.setContentType来设置编码-->
        <init-param>
            <param-name>charset</param-name>
            <param-value>utf-8</param-value>
        </init-param>        
        <load-on-startup>1</load-on-startup>
    </servlet>
    <!--映射模板必须以/PlutoInvoker开头，否则pluto识别不出来-->
    <servlet-mapping>
        <servlet-name>HelloWorldPortal</servlet-name>
        <url-pattern>/PlutoInvoker/*</url-pattern>
    </servlet-mapping>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>


4、创建portlet.xml

<?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>
        <description>My First Portal Demo</description>
        <portlet-name>HelloWorldPortalDemo</portlet-name>
        <display-name>HelloWorld Portal Demo</display-name>
        <portlet-class>com.miiwill.Helloworld</portlet-class>
        <expiration-cache>-1</expiration-cache>
        <supports>
            <mime-type>text/html</mime-type>
            <portlet-mode>VIEW</portlet-mode>
            <portlet-mode>EDIT</portlet-mode>
        </supports>
        <portlet-info>
            <title>My First Portal Demo : HelloWorldPortal</title>
        </portlet-info>
    </portlet>
</portlet-app>


5、部署portal

将WebRoot copy到webapps下，改名为testportal。

注意将WEB-INF\lib中的2 个jar删除，因为pluto的lib中已经有了。不删除会有冲突！

 1）启动pluto,http://localhost:8080/pluto/

    以pluto/pluto登录。

 2）创建一个页


     3）注册portlet

     4）测试portlet
