java enum类自定义属性

enum类自定义属性

这就是enum比static静态变量好用的地方了，可以赋予每一个枚举值若干个属性，例如

实例1：

public enum GasStationChannel {
    ZH("中化", "100001"),
    APP("APP", "100002"),
    QZ("撬装", "100003"),
    ZYW("找油网", "100004"),
    YZG("油掌柜", "100005"),
    YZX("油战线", "100006"),
    SHELL("壳牌", "100007"),
    CHEBEI("车呗", "100008"),
    SHANGAO("山东高速", "100009"),
    GUANDE("冠德", "100010");

    private String name;
    private String code;

    GasStationChannel(String name, String code) {
        this.name = name;
        this.code = code;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public static GasStationChannel parse(String code) {
        if(code==null){
            return null;
        }
        for (GasStationChannel channelType : GasStationChannel.values()) {
            if (channelType.getCode().equals(code)) {
                return channelType;
            }
        }
        return null;
    }

    @Override
    public String toString() {
        return "name:"+this.name+",code:"+this.code;
    }}

　实例2：

public enum Domain {

    XB("11","西北"),
    HD("13","华东"),
    DB("14","东北"),
    HB("15","华北");

    private String code;
    private String name;

    Domain(String code,String name) {
        this.code = code;
        this.name = name;
    }

    public String getCode() {
        return code;
    }
    public String getName(){
        return name;
    }

    /**
     * 根据domain code，返回枚举类型
     */
    public static Domain getDomain(String code) throws Exception {

        Domain domain = null;
        switch (code.trim()) {
            case "11":
                domain = XB;
                break;
            case "13":
                domain = HD;
                break;
            case "14":
                domain = DB;
                break;
            case "15":
                domain = HB;
                break;
            default:
                throw new Exception(String.format("传入的域ID[%s]不存在，请检查！", code));
        }
        return domain;
    }
}

　　以上两种都能实现，根据个人喜好选择，个人更倾向于实例1，代码结构更优美
