我有一些像上面一句话的话我希望得到前面和as关键字之后的值Alias as label and [Column A] as label，因为我正在使用(\s*(?:,\s*\S+\s*)?\S*\s*as\S*(?:\s\S+)?)正则表达式，但它不是为所有案件工作。

您可以使用此regex = " as | AS | aS | As"并使用split（）方法

String mData = "[ColumnA], Alias as label, [Column B] Alias as label, [Column A] ,[Column A] as label, [Column B], Alias as label";
        String [] result = mData.split(" as | AS | aS | As");

        for(String d : result) {
            System.out.println(d);

        }

输出：

[ColumnA], Alias
label, [Column B] Alias
label, [Column A] ,[Column A]
label, [Column B], Alias
label

正则表达式获取'as'关键字之前和之后的值
