枚举类的应用

枚举类的使用=== >展示到页面

0. 创建需要的枚举类  1.赋值

public enum ResumePeopleSizeEnum {
/*公司人数 0:不限 1:1~99 2:100~500 3:500~1000 4:1000~5000 5:5000以上*/
   UNLIMITED(0,"不限"),
   ONE(1,"0~99"),
   TWO(2,"100~500"),
   THREE(3,"500~1000"),
   FOUR(4,"1000~5000"),
   FIVE(5,"5000以上")
   ;
   private Integer code;

   private String message;

   private ResumePeopleSizeEnum(Integer code, String message) {
      this.code = code;
      this.message = message;
   }

   public Integer getCode() {
      return code;
   }

   public String getMessage() {
      return message;
   }
}

将枚举添加到map中

List<Map<String, Object>>  hotCompanyByPage = iSearchService.getHotCompanyByPage(pageNo,pageSize);

for (Map<String, Object> map : hotCompanyByPage) {
int peopleSize =(int) map.get("peoplesize");
switch (peopleSize){
    case 0 :
        map.put("peopleSize", ResumePeopleSizeEnum.UNLIMITED.getMessage());
        break;
    case 1 :
        map.put("peopleSize", ResumePeopleSizeEnum.ONE.getMessage());
        break;
    case 2 :
        map.put("peopleSize", ResumePeopleSizeEnum.TWO.getMessage());
        break;
    case 3 :
        map.put("peopleSize", ResumePeopleSizeEnum.THREE.getMessage());
        break;
    case 4 :
        map.put("peopleSize", ResumePeopleSizeEnum.FOUR.getMessage());
        break;
    case 5 :
        map.put("peopleSize", ResumePeopleSizeEnum.FIVE.getMessage());
        break;
  }
}
