要将ObjectNode代码写入下面的JSON数据,可以按照以下步骤进行:
完整的代码示例:
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.node.ObjectNode;
public class JsonExample {
public static void main(String[] args) {
ObjectMapper objectMapper = new ObjectMapper();
ObjectNode objectNode = objectMapper.createObjectNode();
objectNode.put("key1", "value1");
objectNode.put("key2", "value2");
ObjectNode nestedObjectNode = objectMapper.createObjectNode();
nestedObjectNode.put("nestedKey", "nestedValue");
objectNode.set("nestedObject", nestedObjectNode);
String json = objectNode.toString();
System.out.println(json);
}
}
这段代码将生成以下JSON数据:
{
"key1": "value1",
"key2": "value2",
"nestedObject": {
"nestedKey": "nestedValue"
}
}
