 文件压缩案例2

        OutputStream out2 = response.getOutputStream();
        LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory();
        String fileStr = ((RollingFileAppender) loggerContext.getLogger("ROOT").getAppender("FILE")).getFile();
        String s = Paths.get(fileStr).getParent().toString()+"\\1239000.zip";
        ZipOutputStream out = new ZipOutputStream(new FileOutputStream(s));
        out.putNextEntry(new ZipEntry("1239000.txt"));
        Files.copy(Paths.get(fileStr),out);
        out.flush();
        out.closeEntry();
        out.close();
        Files.copy(Paths.get(s),out2);
        out2.flush();
        out2.close();
