引起：com.fasterxml.jackson.databind.JsonMappingException：无法构造model.UPMSetResult的实例$ UPMMenu：找不到合适的构造函数，无法从Object值反序列化（缺少默认构造函数或创建者，或者可能需要添加/启用类型信息？） 在[来源：java.io.BufferedReader@39688e58; line：1，column：11]（通过引用链：model.UPMSetResult [“data”] - ＆gt; java.util.HashSet [0]）
答案 0 :(得分：0)
我解决了它：只写UPMMenu作为signle类而不是内部类，但为什么？有人可以告诉我杰克逊为此做点什么。
