ObjectMapper转换json内部类报错

1. 异常信息

com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of `com.zhoulp.xxx$Dabc` (although at least one Creator exists): can only instantiate non-static inner class by using default, no-argument constructor

2. 解决方法

在内部类加上static关键字，声明为内部静态类即可
