枚举常用方式
ordinal 枚举下标从0开始
int ordinal = SUCCESS.ordinal(); 获取枚举下标 BusinessStatus success = BusinessStatus.values()[SUCCESS.ordinal()]; 通过下标获取枚举name 枚举名称
String name = SUCCESS.name(); 获取枚举名称 BusinessStatus success = BusinessStatus.valueOf("SUCCESS"); 通名称获取枚举
常规枚举
public enum BusinessStatus {
/**
* 成功
*/
SUCCESS,
/**
* 失败
*/
FAIL,
}
添加属性的枚举
public enum UserStatus {
OK("0", "正常"), DISABLE("1", "停用"), DELETED("2", "删除");
private final String code;
private final String info;
UserStatus(String code, String info) {
this.code = code;
this.info = info;
}
public String getCode() {
return code;
}
public String getInfo() {
return info;
}
}
