解决com.fasterxml.jackson.databind.JsonMappingException: No suitable

原因:直接翻译,json格式,不匹配. 这原因坑爹啊,因为json格式不正确算一种原因. 还有一种就是接收的bean没有getter,setter方法. 最坑的一种就是数据无法被反序列化,list,map之类的. 方法: json格式随便日志输出,网上找个网址check一下就好了. 加getter,setter方法. 加序列化(java 的实体类 implement Serializable等)或者处理序列化(改成jsonString就是一种处理方式哦).…
