是否可以在 felix 的 war bundle 中使用 spring?我在 glassfish 3.1 上使用 spring 3.0.5 和 felix

我试图component-scan在 felix 中的 OSGI 战争包中输入标签,但出现以下异常。

我看到 Equinox 解决了一个类似的错误,那么 felix 呢?是否有解决此问题的解决方法或解决方案?

PS:如果我在 web.xml 中使用 * 定义路径,则会引发相同的异常contextConfigLocation,例如:

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:META-INF/spring/*.xml</param-value>
</context-param>

例外:

我发现有两种解决方法可以解决它。我仍然很高兴听到 felix 的真正解决方案。

解决方法是:

  1. 使用春分代替菲利克斯 :)
  2. (一个丑陋的)创建一个临时文件夹并将所有类提取到其中。用函数创建一个类 org.eclipse.core.runtime.FileLocator

公共静态 URL 解析(URL url)抛出 IOException

并从该文件夹返回内容的 url,例如:

    String path = url.getPath(); 
    String str;
    if(path.contains("com")){
        str = path.substring(path.indexOf("com"));
    }
    return new URL("file:\\c:\\temp_classes\\"+str);

如果您不介意将自己绑在 Felix 上,这是一个稍微优雅的解决方案。

package org.eclipse.core.runtime;

import java.net.URL;

import org.apache.felix.framework.BundleRevisionImpl;
import org.osgi.framework.Bundle;
import org.osgi.framework.FrameworkUtil;

public class FileLocator {
    private FileLocator() {}

    public static URL resolve(URL url) {
        if(url == null) {
            return null;
        }
        Bundle bundle = FrameworkUtil.getBundle(FileLocator.class).getBundleContext().getBundle();
        BundleRevisionImpl bundleRevision = bundle.adapt(BundleRevisionImpl.class);
        return bundleRevision.getLocalURL(url.getPort(), url.getPath());
    }
}

这要求您在 Felix 启动时使用以下参数导出框架:

-Dorg.osgi.framework.system.packages.extra=org.apache.felix.framework
