如何访问OSGi捆绑包中的文件？

URL

File.createTempFile()

URL url = context.getBundle().getResource(\"com/my/weager/impl/test.txt\");

// The url maybe like this: bundle://2.0:2/com/my/weager/impl/test.txt
// But this url is not a real file path :(, you could\'t use it as a file.
// This url should be handled by the specific URLHandlersBundleStreamHandler, 
// you can look up details in BundleRevisionImpl.createURL(int port, String path)
System.out.println(url.toString());

BufferedReader br =new BufferedReader(new InputStreamReader(url.openConnection().getInputStream()));
while(br.ready()){
    System.out.println(br.readLine());
}
br.close();

getResource

getEntry

InputStream inStream = new java.io.BufferedInputStream(this.getClass().getClassLoader().getResourceAsStream(fileName));

static public byte[] readFileAsBytes(Class c, String fileName) throws IOException {
    InputStream inStream = new java.io.BufferedInputStream(c.getClassLoader().getResourceAsStream(fileName));
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    int nbytes = 0;
    byte[] buffer = new byte[100000];

    try {
        while ((nbytes = inStream.read(buffer)) != -1) {
            out.write(buffer, 0, nbytes);
        }
        return out.toByteArray();
    } finally {
        if (inStream != null) { 
            inStream.close();
        }
        if (out != null) {
            out.close();
        }
    }
}
