Java BasicSerializerFactory和带修饰符的NullSerializer的Jackson问题；“私人”；

救命啊！我在寻找创意

我在使用Jackson序列化Java对象时遇到此错误

Class com.fasterxml.jackson.databind.ser.BasicSerializerFactory 
can not access a member of class 
com.fasterxml.jackson.databind.ser.std.NullSerializer 
with modifiers "private"

在其他回应中，这个问题似乎与混合版本的杰克逊有关

但是，我找不到任何碰撞

这还不够：您需要显示尝试用于序列化的代码以及尝试序列化的值

---

问题似乎是由于试图序列化Jackson的一个内部类

NullSerializer

不应序列化。可能使用错误的参数（或以错误的顺序）调用了某些内容。

NullSerializer

不应序列化。可能调用的参数错误（或顺序错误）。

我找到了它。我的一个要序列化的类在如下方法集上有@JsonProperty

@JsonProperty
public void setFoo( int foo ) {
  this.foo = foo;
}

我不知道为什么Jackson失败了，但是删除@json属性解决了这个问题
