利用枚举类进行json输出key value数据格式

public ResponseData customerType() {

    ResponseData res = new ResponseData();
    try {
        CustomerTypeEnums[] customerTypeEnums = CustomerTypeEnums.values();
        List<Map<String,String>> list = new ArrayList<>();
        for (CustomerTypeEnums customerType : customerTypeEnums){
            Map<String,String> map = new HashMap<>();
            map.put("custName",customerType.getCustName());
            map.put("custCode",customerType.getCustCode());
            list.add(map);
        }
        return ResponseData.ok(list,"查询成功");
    } catch (Exception e) {
        log.info("查询失败",e.getMessage());
        res = ResponseData.fail("查询失败");
    }
    return res;
}
