不知道这个 class 字段存的是什么?建议存字符串,然后再通过 Class.forName(string) 得到具体的class。

Class clazz = jsonObject.getObject("clazz", Class.class);

修改为:

String classString = jsonObject.getObject("clazz", String.class);
Class clazz = Class.forName(classString)

引用来自“理工男海哥”的评论

Class clazz = jsonObject.getObject("clazz", Class.class);

修改为:

String classString = jsonObject.getObject("clazz", String.class);
Class clazz = Class.forName(classString)

 

jboot中的代码,fastjson不支持 jsonObject.getObject("clazz",Class.class)

我的意思是jboot里fastjson反序列化,现在就是使用Class class = jsonObject.getObject("class",Class.class)取的

这个应该和 jboot 无关吧
