springboot1.5 集成seata报错

springboot1.5.14 集成seata报错：环境描述：springboot：1.5.14 springcloud：Edgware.RELEASE seata：0.9.0 错误描述：正常启动，但是调用api出错，无法提交事务。

Could not commit JDBC transaction; nested exception is java.sql.SQLException:

java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.jsontype.TypeSerializer.typeId(Ljava/lang/Object;Lcom/fasterxml/jackson/core/JsonToken;)Lcom/fasterxml/jackson/core/type/WritableTypeId;

错误信息为TypeSerializer没有typeId,断定是jackson-databind版本问题，因此升级了jackson-databind版本2.8.11.2==》2.9.8。升级完之后启动直接报错：

但是我查看com.fasterxml.jackson.databind.ObjectMapper确实存在。
升级完之后，不确定是不是哪里版本兼容造成的，目前无法解决这个问题。
apache / incubator-seata
