解析原始日志文件转储并提取相关信息。

以下是两个事件的日志文件提取。每个事件由* *分隔，如下所示：

应用程序日志转储了一系列类似的重复日志。我需要解析这个文件并通过 Java 程序将它输入到 MS Excel 中。

以下是我需要从上面的原始数据转储中获取的相关信息：

01/23/13 17:29:25 |-|   ==> CS Label: [JU , LBCH , 70005023489 , JU Filtrete UPC0 3 Up Label , JU Filtrete UPC0 Labels 3 up , JUCHIZ01 , Qty: 1100]

此原始数据始终以“CS 标签：”开头，后跟“[”，然后有 7 个字段，以逗号分隔。我需要将这七个字段提取到 Excel 工作表中的列中。实现这一目标的最有效方法是什么？

我看到以下算法：

  1. 逐行读取文件。
  2. 如果行包含CS Label字符串，则处理它（否则丢弃）。
  3. 提取方括号之间的所有内容（您可以为此使用正则表达式，或者只是简单的String方法）。
  4. 用逗号分割这个字符串，修剪空格。
  5. 将此信息添加到某个结构并发布到 Excel。

干得好：

public class DateFunctions {
    // Date related Logic
    private Date startDate;
    private Integer delta;

    @SuppressWarnings("resource")
    public DateFunctions() {
        // ApplicationContext ctx = new
        // ClassPathXmlApplicationContext("date-properties.xml");
        ApplicationContext ctx = new FileSystemXmlApplicationContext(
                "c:\\logAnalyzer\\date-properties.xml");
        // Initializing date related data from spring configuration file
        startDate = (Date) ctx.getBean("startDate");
        delta = (Integer) ctx.getBean("delta");
    }

    public boolean isTimeDiffAcceptable(Date logDate) {

        DateTime dt1, dt2;
        Integer minutesDiff;

        dt1 = new DateTime(logDate);
        dt2 = new DateTime(startDate);

        int daysDiff = Days.daysBetween(dt1, dt2).getDays();

        if (daysDiff == 0) {
            minutesDiff = dt1.getMinuteOfDay() - dt2.getMinuteOfDay();
        } else {
            minutesDiff = 0;
        }

        // System.out.println("minutesDiff : " + minutesDiff);
        // System.out.println("delta : " + delta);

        if (minutesDiff < 0 && (-1 * minutesDiff) < delta) {
            return true;
        } else {
            return false;
        }
    }

    public Date getStartDate() {
        return startDate;
    }

    public void setStartDate(Date startDate) {
        this.startDate = startDate;
    }

    public Integer getDelta() {
        return delta;
    }

    public void setDelta(Integer delta) {
        this.delta = delta;
    }

}

然后格式化日志方法将让您将日志放在 Excel 工作表中。

public class FormatLog {

    private String searchRequiredString, searchStartString, searchEndString;
    private String regex, line;
    private Integer lengthStartStr, lengthEndStr;

    private File inputFile;

    private Integer rowNum, colNum;
    private HSSFCell cell;

    private String[] ary;

    private Logger log;

    // Initializing data in constructor
    public FormatLog() {
        // initializing the logger for log4j
        log = Logger.getLogger(FormatLog.class);

        @SuppressWarnings("resource")
        ApplicationContext ctx = new ClassPathXmlApplicationContext(
                "spring.xml");

        // Initializing search String related parameters
        searchRequiredString = (String) ctx.getBean("searchRequiredString");
        searchStartString = (String) ctx.getBean("searchStartString");
        searchEndString = (String) ctx.getBean("searchEndString");
        regex = (String) ctx.getBean("regex");

        // Initializing the Log Input File
        inputFile = (File) ctx.getBean("inputFile");

        // Computing some start parameters
        lengthStartStr = searchStartString.length();
        lengthEndStr = searchEndString.length();

        // Row Number initialized to -1
        rowNum = -1;
    }

    /*
     * Input: None Output: Integer rowNum - number of rows processed.
     */
    @SuppressWarnings({ "resource", "deprecation" })
    public Integer stringManipulation() {

        // setting header text
        String[] headerText = { "Date", "Facility Name", "Work Center",
                "ID Nbr", "Preference", "Format", "Printer Name", "Qty" };
        DateFunctions df = new DateFunctions();
        try {
            FileOutputStream fileOut = new FileOutputStream(
                    "c:\\logAnalyzer\\FormattedLogsELC.xls");
            HSSFWorkbook workbook = new HSSFWorkbook();
            HSSFSheet worksheet = workbook.createSheet("ELC Log Worksheet - "
                    + df.getStartDate().toString());

            BufferedReader br = new BufferedReader(new FileReader(inputFile));
            while ((line = br.readLine()) != null) {
                // Create the StringBuilder
                StringBuilder builder = new StringBuilder(line);

                Integer indexRequired = builder.indexOf(searchRequiredString);
                if (indexRequired > 0) {

                    String date = builder.subSequence(1, 17).toString();
                    log.debug(date);
                    Date logDate = new Date(date);
                    if (df.isTimeDiffAcceptable(logDate)) {

                        log.debug(builder.toString());
                        Integer indexStart = builder.indexOf(searchStartString);
                        Integer indexEnd = builder.indexOf(searchEndString);
                        String s = builder.subSequence(
                                indexStart + lengthStartStr,
                                indexEnd - lengthEndStr + 1).toString();
                        // adding date to the string s
                        s = date + "," + s;
                        log.debug(s);
                        ary = s.split(regex);
                        if (ary.length != headerText.length) {
                            log.warn("Review row number : " + rowNum
                                    + ". Unexpected data was found");
                        }

                        // incrementing RowNumber for workbook calculation.
