               StringBuilder sb = new StringBuilder();

               sb.append(record.getLevel()).append(" : ");

               sb.append(record.getMessage()).append(System.getProperty("line.separator"));

               return sb.toString();

           }

       };

       // 创建一个文件处理器

       FileHandler fileHandler = new FileHandler("myapp.log", 1024000, 100);

       fileHandler.setFormatter(formatter);

       // 添加文件处理器到日志管理器

       LogManager.getLogManager().addLogger(Logger.getLogger("myapp.log"), fileHandler);

       // 记录一些日志

       Logger.getLogger("myapp.log").info("This is a test log message.");

   }
