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
