使用ObjectMapper对象将json转化为对象的时候运行之后是这个，怎么搞的

{"resultcode":"200","reason":"Return Successd!","result":{"province":"江苏","city":"淮安","areacode":"0517","zip":"223001","company":"电信","card":""},"error_code":0}
Exception in thread "main" com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "resultcode" (class pojo.Pespon), not marked as ignorable (3 known properties: "reason", "result", "error_code"])
