> ### 拦截非字符串型参数取值 ###

**【1】 准备枚举类：**

@Getter
    @AllArgsConstructor
    public enum QualificationType {
    
        LEGAL_IDENTITY_CARD_FRONT("LEGAL_IDENTITY_CARD_FRONT", 2, "法人身份证（正）"),
    
        LEGAL_IDENTITY_CARD_BACK("LEGAL_IDENTITY_CARD_BACK", 3, "法人身份证（反）"),
    
        BUSINESS_LICENSE("BUSINESS_LICENSE", 1, "营业执照证"),
    
        AGENT_IDENTIFY_CARD_FRONT("AGENT_IDENTIFY_CARD_FRONT", 4, "代理人身份证（正）"),
    
        AGENT_IDENTIFY_CARD_BACK("AGENT_IDENTIFY_CARD_BACK", 5, "代理人身份证（反）"),
    
        AGENT_ATTORNEY("AGENT_ATTORNEY", 6 ,"代理委托书"),
        ;
    
    
        /**
         * 资质信息枚举Map
         */
        public static Map<String, String> qualificationMap;
    
        static {
            qualificationMap = new LinkedHashMap<>();
            qualificationMap.put(QualificationType.LEGAL_IDENTITY_CARD_FRONT.code, QualificationType.LEGAL_IDENTITY_CARD_FRONT.desc);
            qualificationMap.put(QualificationType.LEGAL_IDENTITY_CARD_BACK.code, QualificationType.LEGAL_IDENTITY_CARD_BACK.desc);
            qualificationMap.put(QualificationType.BUSINESS_LICENSE.code, QualificationType.BUSINESS_LICENSE.desc);
            qualificationMap.put(QualificationType.AGENT_IDENTIFY_CARD_FRONT.code, QualificationType.AGENT_IDENTIFY_CARD_FRONT.desc);
            qualificationMap.put(QualificationType.AGENT_IDENTIFY_CARD_BACK.code, QualificationType.AGENT_IDENTIFY_CARD_BACK.desc);
            qualificationMap.put(QualificationType.AGENT_ATTORNEY.code, QualificationType.AGENT_ATTORNEY.desc);
        }
    
        private String code;
    
        private Integer num;
    
        private String desc;
    
        /**
         * 根据宝付订单状态映射
         */
        public static QualificationType mappingByNum(Integer num) {
            for(QualificationType qualificationType : QualificationType.values()){
                if(qualificationType.getNum().equals(num)){
                    return qualificationType;
                }
            }
            return null;
        }
    
    }

**【2】构建资质枚举信息Map**

/**
         * 资质信息枚举Map
         */
        public static Map<String, String> qualificationMap;
    
        static {
            qualificationMap = new LinkedHashMap<>();
            qualificationMap.put(QualificationType.LEGAL_IDENTITY_CARD_FRONT.code, QualificationType.LEGAL_IDENTITY_CARD_FRONT.desc);
            qualificationMap.put(QualificationType.LEGAL_IDENTITY_CARD_BACK.code, QualificationType.LEGAL_IDENTITY_CARD_BACK.desc);
            qualificationMap.put(QualificationType.BUSINESS_LICENSE.code, QualificationType.BUSINESS_LICENSE.desc);
            qualificationMap.put(QualificationType.AGENT_IDENTIFY_CARD_FRONT.code, QualificationType.AGENT_IDENTIFY_CARD_FRONT.desc);
            qualificationMap.put(QualificationType.AGENT_IDENTIFY_CARD_BACK.code, QualificationType.AGENT_IDENTIFY_CARD_BACK.desc);
            qualificationMap.put(QualificationType.AGENT_ATTORNEY.code, QualificationType.AGENT_ATTORNEY.desc);
        }

**【3】枚举类通过map转为list**

/**
         * 枚举类通过map转为list
         * @param map         map集合
         * @return           资质信息集合
         */
        private List<DirQualification> transferEnumMapToList(Map<String,String> map){
            List<DirQualification> dirQualificationList = new ArrayList<>();
    
            Iterator<Map.Entry<String, String>> entries = map.entrySet().iterator();
            while (entries.hasNext()) {
                Map.Entry<String, String> entry = entries.next();
                DirQualification dirQualification = new DirQualification();
                dirQualification.setCode(entry.getKey());
                dirQualification.setDesc(entry.getValue());
                dirQualificationList.add(dirQualification);
            }
          return  dirQualificationList;
        }

**【4】判断枚举Map中是否含有请求参数值**

boolean contains = map.containsKey(key); 
    该方法判断Map集合对象中是否包含指定的键名。如果Map集合中包含指定的键名，则返回true，否则返回false。
