帮助！我正在寻找想法
使用Jackson序列化我的Java对象时出现此错误。
Class com.fasterxml.jackson.databind.ser.BasicSerializerFactory
can not access a member of class
com.fasterxml.jackson.databind.ser.std.NullSerializer
with modifiers "private"
在其他回复中，这个问题似乎与杰克逊混合版本有关。
Spring : FasterXML cannot access a member of class with modifiers private
然而，我找不到任何碰撞。
