JsonNode childNode = rootNode.get("persons"); To convert the entire JSON into aJsonNodeobject, we use thereadTree()method. We then traverse theJsonNodeobject using theget()method that returns the nested object with the specified name. 3. Manual Conversion Before checking library methods, let...
JsonNode nestedElement = jsonNode.get("nestedElement"); 可以进一步使用JsonNode对象的方法获取嵌套元素的值,例如asText、asInt、asBoolean等。 代码语言:txt 复制 String value = nestedElement.asText(); 如果需要获取更深层次的嵌套元素,可以继续使用get方法进行嵌套调用。
