Question

是否有可能在felix上使用war war war？我在glassfish 3.1上使用了弹簧3.0.5和felix

我试图在felix中的OSGI war bundle中输入component-scan标签，我得到以下异常。

我看到Equinox解决了similar bug，那么felix呢？是否有针对此问题的解决方法或解决方案？

P.S：如果我在web.xml contextConfigLocation中使用*定义路径，则抛出相同的异常，例如：

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

例外：

感谢您的任何提示

Answer 1

我找到了解决它的2个解决方法。我仍然很高兴听到felix真正的解决方案。

解决方法是：

使用equinox代替felix：）
（一个丑陋的）创建一个临时文件夹并将所有类提取到其中。使用函数

public static URL resolve（URL url）抛出IOException

并返回此文件夹中的内容网址，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);

Answer 2

如果你不介意将自己绑在菲利克斯身上，那就是一个更优雅的解决方案。

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());
    }
}

这要求您使用以下参数在Felix启动时导出框架：

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

Spring + Felix war = FileNotFoundException
