我有一个rest在tomcat.
回复时 - 类型的对象ActionError作为json字符串发送给客户端。
ActionError将传递给客户
ArrayStrings2个Array的FieldError_- 任意
Object有效负载（定义为泛型类型）。
在我的测试中，我作为payload类型的对象传递Employee。
通过上述安排 - 一切正常。我得到的结果如下：
{"actionErrors":["everything is ok"],"fieldErrors":null,"payload":{"empName":"Jony","empNo":"E3","position":"Manager"}}
但是，如果我删除Arrayof FieldError( private ArrayList<FieldError> fieldErrors;) 部分，那么 -现在 ActionError只包含：
1.Array 的Strings
2.Object payload
然后奇怪的payload 是没有正确序列化，我得到：
{"actionErrors":["everything is ok"],"payload":"com.mycompany.mavenwebproject.model.Employee@41a8e0d9"}
是什么原因造成的？关于如何修复它的任何想法？
谢谢。
以下是类定义：
