如何解决异常-“无法从START_OBJECT令牌中反序列化`java.util.ArrayList`的实例”

时间：2019-11-21 06:08:50

标签： java json playframework jackson deserialization

我从API获取JSON响应，并尝试将其保存在POJO SiebelResponse中。之前它可以正常工作，但是由于我的重构更改，它突然停止了，我花了很多时间来解决这个问题，但是仍然无法解决。

SHMSite类中某个地方存在一个愚蠢的错误。我不知道在哪里。当我反序列化对POJO的JSON响应时，出现错误：

Exception occured: Cannot deserialize instance of java.util.ArrayList out of START_OBJECT token
 at [Source: UNKNOWN; line: -1, column: -1] (through reference chain: com.confidential.api.siebel.models.SiebelResponse["SiebelMessage"]->com.confidential.api.siebel.models.SiebelMessage["SHM Site"]->com.confidential.api.siebel.models.SHMSite["Internal Product - ISS Admin"])

注意 ：我正在使用Play framework。

以下是JSON响应：

                {

                    "Id": "141-GV8J61",
                    "Type": "Sleeping Room"
                },
                {

                }

    }
