storm topology all in one spring文件合并

storm生成topology all in one的jar包时，如果是spring环境，就会出现问题，各种资源文件无法找到，写了个工具方法，合并并生成这些资源文件：

 

public class MergeMetaInf {

	public static void main(String[] args) throws IOException, URISyntaxException {
		File metaInfDir = new File("src/main/resources");
		ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
		for (String name : new String[] {"META-INF/spring.factories", "META-INF/spring.handlers", "META-INF/spring.schemas", "META-INF/spring.tooling"}) {

			File file = new File(metaInfDir, name);
			if (!file.getParentFile().exists()) file.getParentFile().mkdirs();
			try (OutputStream out = new FileOutputStream(file)) {
				
				for (Enumeration<URL> iter = classLoader.getResources(name); iter.hasMoreElements();) {
					URL url = iter.nextElement();
					if (!url.getProtocol().equals("file")) {
						UtilIO.write(url.openStream(), out);
						out.write('\n');
					}
				}
			}
		}
	}
}
