异常一 JSON parse error: Can not deserialize instance of java.lang.Long out of START_OBJECT token; nested...com.fasterxml.jackson.databind.JsonMappingException: Can not deserialize instance of java.lang.Long out of START_OBJECT
具体表现为出现 "Cannot deserialize instance of java.lang.String out of START_OBJECT token" 错误。...通过以上方式，我们可以成功解析 JSON 数据并获取到 code 和 data 的数值，避免了 "Cannot deserialize instance of java.lang.String out of START_OBJECT
redisTemplate 报错： Caused by: com.fasterxml.jackson.databind.JsonMappingException: Unexpected token (START_OBJECT
org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Cannot deserialize instance of 'java.util.ArrayList' out of START_OBJECT...而Cannot deserialize instance of 'java.util.ArrayList' out of START_OBJECT token 则指出了具体的问题是在尝试将JSON对象反序列化为
import xml.etree.ElementTree as et class Serializer(metaclass=ABCMeta): @abstractmethod def start_object..._current_object = None def start_object(self, object_name, object_id): self...._element = None def start_object(self, object_name, object_id): self...._element, encoding='unicode') Serializer接口将上述的json和xml序列化方法抽象成了三个方法： start_object(object_name, object_id
com.fasterxml.jackson.databind.JsonMappingException: Can not deserial ize instance of java.lang.String out of START_OBJECT

org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Cannot deserialize instance of `java.util.ArrayList` out of START_OBJECT...com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `java.util.ArrayList` out of START_OBJECT
} switch (token) { case END_OBJECT: continue; case START_OBJECT
list //使用json1报错，此时需要数组/集合类型： Can not deserialize instance of TEst.UserBase[] out of START_OBJECT
public enum JsonToken { NOT_AVAILABLE(null, JsonTokenId.ID_NOT_AVAILABLE), START_OBJECT("{", JsonTokenId.ID_START_OBJECT...break; } } } } 运行程序，输出： {"name":"YourBatman","age":18, "pickName":null} START_OBJECT
=token类型是：VALUE_STRING YourBatman ==============token类型是：VALUE_NUMBER_INT 18 ==============token类型是：START_OBJECT...public enum JsonToken { START_OBJECT("{", JsonTokenId.ID_START_OBJECT), END_OBJECT("}", JsonTokenId.ID_END_OBJECT
case (START_OBJECT, st: StructType) => convertObject(factory, parser, st) 如果你的JSON是个Map,经过N次匹配
throw new ParsingException(parser.getTokenLocation(), "[_na] query malformed, must start with start_object...throw new ParsingException(parser.getTokenLocation(), "[_na] query malformed, no field after start_object..."); } String queryName = parser.currentName(); // move to the next START_OBJECT...throw new ParsingException(parser.getTokenLocation(), "[" + queryName + "] query malformed, no start_object
这些常量是： START_OBJECT END_OBJECT START_ARRAY END_ARRAY FIELD_NAME VALUE_EMBEDDED_OBJECT VALUE_FALSE VALUE_TRUE
