Java 使用 uniVocity 解析器特定列数据有逗号且未括起来

Question

我主要使用uniVocity作为CSV解析器，它是一个优秀的解析器。我遇到了以下行的问题，该文件将有固定数量的 7 列。问题是客户端名称，它可以有逗号，它的下一列类型，一般是S或P。

下面是测试数据

Date,Code,Company,Client,Type,Quantity,Price
03/03/2014,500103,BHEL,PoI THROUGH DoI, Affairs,S,114100000,165.55
21/04/2017,533309,DALMI,KKR MAURITIUS CEMENT, LTD.,S,106020,2050.00
21/04/2017,533309,DALMI,KKR MAURITIUS CEMENT, LTD.,P,141740,2050.00

以上数据的客户端名称有问题，因为数据本身有逗号且未括起来。以下是客户名称

PoI THROUGH DoI, Affairs
KKR MAURITIUS CEMENT, LTD.
KKR MAURITIUS CEMENT, LTD.

请告诉我如何处理

谢谢

如果数据没有用引号括起来，那么您实际上无法在这里做很多事情。您实际上能做的就是检查行长度，如果它大于 7，您就知道额外的列是客户端名称的一部分。

这是我的解决方案:

for (String[] row : rows) {
        if (row.length > 7) {
            int extraColumns = row.length - 7; //we have extra columns
            String[] fixed = new String[7]; // let's create a row in the correct format

            //copies all data before name
            for (int i = 0, j = 0; i < row.length; i++, j++) {
                fixed[j] = row[i]; //keep copying values, until we reach the name

                if (i == 3) { //hit first column with a name in it
                    for (int k = i + 1; k <= i + extraColumns; k++) { //append comma and the value that follows the name
                        fixed[i] += ", " + row[k];
                    }

                    i += extraColumns; //increase variable i and keep assigning values after it to position j
                }
            }
            row = fixed; //replaces the original broken row
        }

        //prints the resulting row, values in square brackets for clarity.
        for (String element : row) {
            System.out.print('[' + element + ']' + ",");
        }
        System.out.println();
    }

这会产生输出:

[Date],[Code],[Company],[Client],[Type],[Quantity],[Price],
[03/03/2014],[500103],[BHEL],[PoI THROUGH DoI, Affairs],[S],[114100000],[165.55],
[21/04/2017],[533309],[DALMI],[KKR MAURITIUS CEMENT, LTD.],[S],[106020],[2050.00],
[21/04/2017],[533309],[DALMI],[KKR MAURITIUS CEMENT, LTD.],[P],[141740],[2050.00],

希望有帮助。
