Split String json

Question

我有字符串结果=

{"fkcl":"5","fkdiv":["1","2","3","4","5"],"fkcl1":"3","fkdiv1":["1","2","3","4","5"]}

我想拆分为

[{"fkcl":"5","fkdiv":["1","2","3","4","5"]}]
[{"fkcl1":"3","fkdiv":["1","2","3","4","5"]}]

Answer 1

如果您知道这些项始终以字符串"fkcl"开头，那么您可以使用正则表达式来执行此操作。 E.g。

String json = "{\"fkcl\":\"5\",\"fkdiv\":[\"1\",\"2\",\"3\",\"4\",\"5\"],\"fkcl1\":\"3\",\"fkdiv1\":[\"1\",\"2\",\"3\",\"4\",\"5\"]}";

String output = json
    .replaceAll("\\{?(\"fkcl)", "\n[{$1")
    .replaceAll(",\n", "}]\n") + "]";

System.out.println(output);

产地：

[{"fkcl":"5","fkdiv":["1","2","3","4","5"]}]
[{"fkcl1":"3","fkdiv1":["1","2","3","4","5"]}]

否则使用JSON解析器（例如GSON）解析字符串，然后迭代元素并在需要时进行拆分。
