        String path = "E:/apps/abc.json";
        {
            File file = new File(path);
            ObjectMapper mapper = new ObjectMapper();
            Abc abc= null;
            try {
                JsonNode jsonNode = mapper.readTree(file);
                abc= mapper.treeToValue(jsonNode, Abc.class);
            } catch (IOException e) {
                log.error("解析{}异常,失败信息:{}", file.getName(), e.getMessage());
