Question

我试图突出显示客户端发送的修复消息的错误。但是，这样做时不会遵循此算法。如果修复消息中只有一个字符串出现错误，它将突出显示整个字符串，否则它将不会突出显示。基本上我要问的是如何突出显示多个部分，而不是在出现错误时突出显示整个输出？

例如：我得到的错误

no error - unhighlighted
error - highlighted
no error - highlighted
no error - highlighted
no error - highlighted
error - highlighted

我想要的是什么：

no error - unhighlighted
error - highlighted
no error - unhighlighted
no error - unhighlighted
no error - unhighlighted
error - highlighted

问题区域

if(outputLine.equals("No errors")) {
    tfCSVLine.append(outputLine+"\n\n\n");
    lengthH += (inputLine+"\n\n\n").length();
}
else {
    tfCSVLine.append(outputLine+"\n\n\n");
    int pos = inputLine.indexOf(inputLine, 0);
    int len = lengthH;
    lengthH += (inputLine+"\n\n\n").length();
    h.addHighlight(len, lengthH+(inputLine+"\n\n\n").length(),
                                DefaultHighlighter.DefaultPainter);
}

程序

Highlighter h =  tfFIXMsg.getHighlighter();
try {             
    int lengthH = 0;
    while ((inputLine = in.readLine()) != null) { 
        System.out.println ("Server: " + inputLine); 
        tfFIXMsg.append( inputLine + "\n\n\n");

        if (inputLine.trim().equals("Bye.")) {
            System.out.println("Exit program"); 
            break;
        }

        Scanner input1 = new Scanner(new File(csvName));
        Scanner input2 = new Scanner(new File(csvName));
        Scanner input3 = new Scanner(new File(csvName));
        Scanner input4 = new Scanner(new File(csvName));

        String csvline = getCsvLineVal(getLocation34CSV(
                getTag34Value(Tag34Location(getTagCSV(parseFixMsg(
                    inputLine ,inputLine))), getValueCSV( parseFixMsg(
                        inputLine ,inputLine))), getVal34(input1,input2)),
                                            getCSVLine( input3,  input4) );
        outputLine = compareClientFixCSV( getTagCSV(parseFixMsg(
                inputLine ,inputLine)), getValueCSV(parseFixMsg(
                    inputLine ,inputLine)), getCSVTag(csvline), getCSVValue(csvline));

        out.println(outputLine);

        if(outputLine.equals("No errors")) {
            tfCSVLine.append(outputLine+"\n\n\n");
            lengthH += (inputLine+"\n\n\n").length();
        }
        else {
            tfCSVLine.append(outputLine+"\n\n\n");
            int pos = inputLine.indexOf(inputLine, 0);
            int len = lengthH;
            lengthH += (inputLine+"\n\n\n").length();
            h.addHighlight(len, lengthH+(inputLine+"\n\n\n").length(),
                                    DefaultHighlighter.DefaultPainter);
        }

        input1.close();
        input2.close();
        input3.close();
        input4.close();
}

您要将(inputLine+"\n\n\n").length()两次添加到长度。你应该这样做一次吗？此外，当'else'块执行时，看起来长度是否正确初始化？

如何分别突出显示
