试图在Equinox容器中部署 Spring的mvc-basic.

简短错误(完整如下)：

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring   NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/context]
Offending resource: ServletContext resource [/WEB-INF/spring/app-config.xml]

mvc-basic的app-config.xml：
https://src.springframework.org/svn/spring-samples/mvc-basic/trunk/src/main/webapp/WEB-INF/spring/app-config.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:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <!-- Scans the classpath of this application for @Components to deploy as beans -->
    <context:component-scan base-package="org.springframework.samples.mvc.basic" />

web-console的applicationContext.xml：
https://src.springframework.org/svn/spring-osgi/tags/spring-osgi-1.2.1/samples/web-console/war/src/main/webapp/WEB-INF/applicationContext.xml

略有改变(即,将spring-context.xsd更改为spring-context-3.0.xsd)以匹配mvc-basic的app-config.xml(补丁在下面链接)：

<?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:osgi="http://www.springframework.org/schema/osgi"
    xsi:schemaLocation="
      http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
      http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
      http://www.springframework.org/schema/osgi http://www.springframework.org/schema/osgi/spring-osgi.xsd">

    <!-- OSGi package admin service reference -->   
    <osgi:reference id="packageAdmin" interface="org.osgi.service.packageadmin.PackageAdmin"/>

    <context:component-scan
        base-package="org.springframework.osgi.samples.console.service" />

参考来源：
https://src.springframework.org/svn/spring-osgi/tags/spring-osgi-1.2.1/samples/web-console

修补程序将Spring更新为3.0.3.RELEASE并使上下文schemaLocation完全等于mvc-basic：

编辑：刚试用Spring DM 2.0.0.M1,开箱即用Spring 3.0.0.RC1.

相关的.bundles文件是：
弹簧OSGi的2.0.0.M1.bundles
http://gist.github.com/633280

弹簧OSGi的2.0.0.M1-与-MVC-basic.bundles
http://gist.github.com/633283

2.0.0.M1参考源：
https://src.springframework.org/svn/spring-osgi/tags/spring-osgi-2.0.0.M1/samples/web-console

不幸的是,2.0.0.M1 org.springframework.osgi.* jars在任何软件包存储库中都不可用(据我所知),所以你必须首先从这个subversion repo下载并编译spring-osgi-2.0.0.M1：
https://src.springframework.org/svn/spring-osgi/tags/spring-osgi-2.0.0.M1

解决方法

结果是需要OsgiBundleXmlWebApplicationContext.有用的参考：
http://static.springsource.org/osgi/docs/current/reference/html/web.html

检索相关补丁：

wget http://gist.github.com/raw/648295/452aaeeceed8fae6b9a4d035a5c2d2ad939f65bf/mvc-basic-osgi-works.patch

使用OSGi启动mvc-basic的命令：

svn checkout https://src.springframework.org/svn/spring-samples/mvc-basic/trunk --quiet && cd trunk && patch -p0 < ../mvc-basic-osgi-works.patch && mvn clean install -DskipTests && bash run.sh

这假设您已将mvc-basic-osgi-works.patch下载到当前文件夹中.

有些东西似乎仍然不起作用,例如${pageContext …}标签,但除此之外似乎有效.
