前面使用JS格式化textarea中的日志内容,但局限于JS语言性能,在日志内容较多时效率无法接受,建议日志内容大于5000行时转投本java程序,文末提供jar包下载。
LogsFormat.java
package com.geostar.gfstack.docker.util; import com.google.gson.JsonObject; import com.google.gson.JsonParser; import org.apache.commons.io.IOUtils; import java.io.*; /** * @author 王睿 * @date 2019-01-17 10:54 */ public class LogsFormat { public static void main(String[] args) throws IOException { if (args.length == 0) { System.err.println("请输入第一个参数:日志文件路径"); return; } String fileName = args[0]; InputStream is = LogsFormat.class.getResourceAsStream("/templates/DockerLogsTemplate.html"); String html = IOUtils.toString(is, "UTF-8"); File file = new File(fileName); String text = IOUtils.toString(new FileInputStream(file), "UTF-8"); String[] arr = text.split("\n"); JsonParser parser = new JsonParser(); String time, log, stream; StringBuilder sb = new StringBuilder(1024 * 10); for (int i = 0; i < arr.length; i++) { try { JsonObject jsonObject = parser.parse(arr[i]).getAsJsonObject(); time = jsonObject.get("time").getAsString(); log = jsonObject.get("log").getAsString(); stream = jsonObject.get("stream").getAsString(); sb.append("<tr"); if ("stderr".equals(stream)) { sb.append(" class=‘stderr‘"); } sb.append("><td>"); sb.append(i + 1); sb.append("</td><td>"); sb.append(time); sb.append("</td><td>"); sb.append(log); sb.append("</td></tr>"); } catch (Exception e) { e.printStackTrace(); } } html = html.replace("<![data]>", sb.toString()); File outFile = new File(file.getPath() + ".html"); OutputStreamWriter out = new OutputStreamWriter(new FileOutputStream(outFile), "UTF-8"); out.write(html); out.close(); System.out.println("Docker日志格式化成功,请查看:" + outFile.getAbsoluteFile()); } }

执行 mvn clean compile assembly:single 构建可执行jar包即可使用,执行jar包时Docker原始日志文件作为第一个参数,在同目录下即可生成同名html文件,使用浏览器打开查看即可。
