英文:
Parse list of list to a JSON object
问题
我有以下数据，它是一个列表的列表：
"segmentation": [[239.97,260.24,222.04,270.49,199.84,253.41,213.5,227.79,259.62,200.46,274.13,202.17,277.55,210.71,249.37,253.41,237.41,264.51,242.54,261.95,228.87,271.34]]
我需要做的是将这些信息解析为一个 JSON 对象，而不移除第二层括号。
我尝试过使用 Jackson，但对于任何数据类型都失败了。
你有任何处理这个的想法吗？

What I need to do is to parse the information to a JSON object without removing the second braces.
I tried it with Jackson, but this fails with any data types.
Do you have any idea how to handle this?

以下是翻译好的内容：
解析为 `JsonNode` 将起作用。我认为您尝试了无效的 JSON。请检查：
String value = "{\n" +
" \"segmentation\": [\n" +
" [\n" +
" 239.97,\n" +
" 260.24,\n" +
" 222.04,\n" +
" 270.49,\n" +
" 199.84,\n" +
" 253.41,\n" +
" 213.5,\n" +
" 227.79,\n" +
" 259.62,\n" +
" 200.46,\n" +
" 274.13,\n" +
" 202.17,\n" +
" 277.55,\n" +
" 210.71,\n" +
" 249.37,\n" +
" 253.41,\n" +
" 237.41,\n" +
" 264.51,\n" +
" 242.54,\n" +
" 261.95,\n" +
" 228.87,\n" +
" 271.34\n" +
" ]\n" +
" ]\n" +
"}";
JsonNode jsonNode = new ObjectMapper().readTree(value);
英文:
Parse to JsonNode will work. I think u try with invalid json. check:
String value = "{\n" +
" \"segmentation\": [\n" +
" [\n" +
" 239.97,\n" +
" 260.24,\n" +
" 222.04,\n" +
" 270.49,\n" +
" 199.84,\n" +
" 253.41,\n" +
" 213.5,\n" +
" 227.79,\n" +
" 259.62,\n" +
" 200.46,\n" +
" 274.13,\n" +
" 202.17,\n" +
" 277.55,\n" +
" 210.71,\n" +
" 249.37,\n" +
" 253.41,\n" +
" 237.41,\n" +
" 264.51,\n" +
" 242.54,\n" +
" 261.95,\n" +
" 228.87,\n" +
" 271.34\n" +
" ]\n" +
" ]\n" +
"}";
JsonNode jsonNode = new ObjectMapper().readTree(value);
