regex Java拆分逗号分隔的字符串，但忽略引号，花括号和递归括号内的逗号
我有这样的字符串行：
valueA,{"property1":"value1","property2":"[[[1.5,1.7],[1.9,0.7],.....,[0.5,0.9]]]","property3":"value3",.....,"propertyn":"valueN"},valueB,{"property1":"value1","property2":"[[[1.5,1.7],[1.9,0.7],.....,[0.5,0.9]]]","property3":"value3",.....,"propertyn":"valueN"},valueC,{"property1":"value1","property2":"[[[1.5,1.7],[1.9,0.7],.....,[0.5,0.9]]]","property3":"value3",.....,"propertyn":"valueN"}
我想用逗号分开
上面的字符串应分为：
valueA
{"property1":"value1","property2":"[[[1.5,1.7],[1.9,0.7],.....,[0.5,0.9]]]","property3":"value3",.....,"propertyn":"valueN"}
valueB
{"property1":"value1","property2":"[[[1.5,1.7],[1.9,0.7],.....,[0.5,0.9]]]","property3":"value3",.....,"propertyn":"valueN"}
valueC
{"property1":"value1","property2":"[[[1.5,1.7],[1.9,0.7],.....,[0.5,0.9]]]","property3":"value3",.....,"propertyn":"valueN"}
尝试一下，但效果不佳。
String[] tokens = line.split(",(?=(?:[^\"]*\"[^\"]*\")*[^\"]*$)", -1);
我怎样才能做到这一点？

与其拆分，不如尝试使用模式匹配器提取数据。
String line = "valueA,{\"property1\":\"value1\",\"property2\":\"[[[1.5,1.7],[1.9,0.7],.....,[0.5,0.9]]]\",\"property3\":\"value3\"},valueB,{\"property1\":\"value1\",\"property2\":\"[[[1.5,1.7],[1.9,0.7],.....,[0.5,0.9]]]\",\"property3\":\"value3\"},valueC,{\"property1\":\"value1\",\"property2\":\"[[[1.5,1.7],[1.9,0.7],.....,[0.5,0.9]]]\",\"property3\":\"value3\"}"; Pattern pattern = Pattern.compile("([,]*(value[A-Z])),(\\{\"[\\w\":,\\[\\].]+\"\\})"); Matcher matcher = pattern.matcher(line); List<String> data = new ArrayList<>(); while (matcher.find()) { String key = matcher.group(2); String value = matcher.group(3); data.add(key); data.add(value); System.out.println(key); System.out.println(value); } String[] array = data.toArray(new String[0]);结果输出：
valueA {"property1":"value1","property2":"[[[1.5,1.7],[1.9,0.7],.....,[0.5,0.9]]]","property3":"value3"} valueB {"property1":"value1","property2":"[[[1.5,1.7],[1.9,0.7],.....,[0.5,0.9]]]","property3":"value3"} valueC {"property1":"value1","property2":"[[[1.5,1.7],[1.9,0.7],.....,[0.5,0.9]]]","property3":"value3"}回答来源：Stack Overflow
