拆分逗號分隔的字符串，但忽略逗號整個字

Question

我有一個字符串，如：

String test = "firstName:a,lastName:b,addressOne:line 1,line 2,city:other"; 

我試圖做test.replaceAll(",","\",\"")。我的意思是取代，用「」。我只想要這整個琴絃。例如，addressOne是一個單獨的字符串，用逗號分隔，我不想替換它。有沒有任何正則表達式或其他方式我可以做到這一點？ 我應該像

"firstName":"a","lastName":"b","addressOne":"line 1 , line 2","city":"other" 
after replace , but i am getting 
"firstName":"a","lastName":"b","addressOne":"line 1 "," line 2","city":"other".

您可以用後跟其一直遵循的:一個字逗號分割你的字符串的字符串。而對於這個目的，你可以使用一個positive look-ahead和匹配的開頭字用一個否定的字符類[^:,]+將匹配任何字符串，除了:和,：

test.split(",(?=[^:,]+:)")
