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_问答-阿里云开发者社区

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？问题来源：Stack Overflow 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 2020-03-26 17:57:01 企业邮箱发送邮件时，若出现投递失败产生退信，内容提示包含如下： the mta server of * reply:550 failed to meet SPF requirements 或者 the mta server of 163.com — 163mx01.mxmail.netease.com(220.181.14.141) reply:550 MI:SPF mx14,QMCowECpA0qTiftVaeB3Cg—.872S2 1442548128 http://mail.163.com/help 304016
