java – org.codehaus.jackson.JsonParseException：意外的字符(

像这样：

{"Davide":{"name":"Davide","cf":"FRCDVD","pi":"1234","telephone":"333","website":"www","sector":"Student","address":"Rome"}}

这只是列表的一个客户.
每次调用控制器时,我都想从文件中获取数据并将它们转换为HashMap列表.

我尝试这样做：

HashMap<String,Customer> listCustomer = new HashMap<>();
listCustomer = new ObjectMapper().readValue(pathCustomerFile,HashMap.class); //This line gives me error

我收到了这个错误：

org.codehaus.jackson.JsonParseException: Unexpected character (‘/’ (code 47)): maybe a (non-standard) comment? (not recognized as one since Feature ‘ALLOW_COMMENTS’ not enabled for parser)

我怎样才能做到这一点？
