Java 带OSGi的SpringMVC-如何注册新控制器-第二部分？

我有maven web应用程序，SpringWebMVC和我在主应用程序@RequestMapping注释中使用的是什么

<context:component-scan
       base-package="net.arturik.testosgispring.controllers" />
<mvc:annotation-driven />

控制器代码，我希望映射到URL的内容：

package net.arturik.testosgispring.controllers.q;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class C1 {

    @RequestMapping(value = "/77777", method = RequestMethod.GET)
    public ModelAndView getdata() {

        ModelAndView model = new ModelAndView("index");

        return model;

    }

}

dispatcher-context.xml文件的内容为

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:security="http://www.springframework.org/schema/security"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="

        http://www.springframework.org/schema/context/spring-context-4.1.xsd
        http://www.springframework.org/schema/security 
        http://www.springframework.org/schema/security/spring-security-3.2.xsd">

    <context:annotation-config />
    <context:component-scan
        base-package="net.arturik.testosgispring.controllers.q" annotation-config="true" />

    <bean name="/helloWorld.htm"
          class="net.arturik.testosgispring.controllers.q.C1" />


    <mvc:annotation-driven />


</beans>

看起来您用Spring的东西创建了一个单独的包，或者是从某处获得的。因此，包含

FileSystemXmlApplicationContext

类的捆绑包的类路径无法看到您的本地类。因此出现了

ClasssNotFoundException

当然，您可以调整类加载器，例如在创建上下文之前将bundle类加载器设置为线程，但我强烈建议您不要使用Spring/OSGi组合

Spring（更具体地说：具有所有隐藏魔法的更高版本）和OSGi实际上并不协同工作。这是众所周知的，这就是为什么你的问题没有得到太多回应的原因。相信我，你所走的道路会带来很多困难，很可能会走到死胡同

如果必须使用这种组合，那么最好使用其他容器，如ApacheKaraf。我不使用它，但我知道其他人在这方面取得了一些成功。

我们可以尝试使用Felix的“嵌入依赖项”。 另一个选择是在Spring上启动felix

另一个选择是使用MSF4J，它构建在OSGi之上
