搭建osgi web 开发环境

开发环境
java1.8
myeclipse Spring2014
打开myeclipse的运行配置界面选择 osgi framework 并在目标平台勾选以下bundle
1.org.eclipse.osgi
2.org.eclipse.equinox.console
3.org.apache.felix.gogo.command
4.org.apache.felix.gogo.runtime
5.org.apache.felix.gogo.shell
6.Javax.servlet
7.Org.apache.commons.loggin
8.Org.eclipse.equinox.http.jetty
9.org.eclipse.equinox.http.servlet
10.Org.eclipse.jetty.http
11.Org.eclipse.jetty.io
12.Org.eclipse.jetty.util
13.Org.eclipse.jetty.server
14.Org.eclipse.jetty.continuation
15.Org.eclipse.jetty.servlet
16.Org.eclipse.jetty.security
运行OSGI的开发环境
主要： 启动时如果出现端口号被占用了
就在启动配置项的 arguments选项的第二个框追加以下内容（主要要先加个空格）
-Dorg.osgi.service.http.port=8080

首先新建一个插件项目
在项目中配置依赖如下

Import-Package: javax.servlet;version="2.6.0", javax.servlet.http;version="2.6.0", org.osgi.framework;version="1.3.0", org.osgi.service.http;version="1.2.1"

在src下新建page目录在其下新建一个hello.html文件
文件内容如下：

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN""http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>demo</title></head><body>Hello,World!</body></html>

在该项目绑定的Activator下进行服务注册
具体方法实现如下：

package com.hz.example.hello.web;import org.osgi.framework.BundleActivator;import org.osgi.framework.BundleContext;import org.osgi.framework.ServiceReference;import org.osgi.service.http.HttpService;import org.osgi.service.http.NamespaceException;import com.hz.example.consoleCommand.BundleNameCommand;public class Activator implements BundleActivator {    private ServiceReference serviceReference;    private HttpService httpService;    private static BundleContext bundleContext;    public void start(BundleContext context) throws Exception {        System.out.println("Hello World!!");        this.bundleContext =  context;        registerResource();    }    /**     * 注册web服务     */    private void registerResource() {        try {            serviceReference = bundleContext.getServiceReference(HttpService.class.getName());            if(serviceReference!=null){                httpService = (HttpService)bundleContext.getService(serviceReference);                //页面的请求地址为http://127.0.0.1:8080/demo/hello.html                httpService.registerResources("/demo", "page", null);            }        } catch (NamespaceException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }    public void stop(BundleContext context) throws Exception {        System.out.println("Goodbye World!!");        unregisterResource();    }    private void unregisterResource() {        try {            httpService.unregister("/demo");        } catch (Exception e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }}
