负数转正整数 Enum枚举

负数转正整数

 

Long user = ~(Long.parseLong(userId)-1);

Math.abs(userId)

Enum枚举

 

几种常用的枚举

一、直接写成员

public enum EnumResultType {
    ex,notMatch,success,busy
}

成员取出是用这种，值为下标

EnumResultType.枚举成员名称.ordinal()

二、K-V的枚举

import lombok.Getter;
import lombok.Setter;

public enum MessageEnum {

    /**
     * 待审批提醒
     */
    APPROVAL_WAIT("10", "您有一条新的请假申请待审核"),

    /**
     * 催办提醒
     */
    APPROVAL_URGED("20", "{username}同学的请假申请还未处理,请及时对内容进行审核。"),

    /**
     * 审批成功结果通知提醒
     */
    APPROVAL_SUCCESS("30", "您有一条新的请假审核成功结果通知"),

    /**
     * 审批失败结果通知提醒
     */
    APPROVAL_FAIL("40", "您有一条新的请假审核失败结果通知"),

    /**
     * 抄送通知提醒
     */
    APPROVAL_SEND("50", "您有一条新的抄送通知"),

    /**
     * 进校门抄送通知提醒
     */
    PEOPLE_IN_ACCESS("60","家长你好，您的孩子已经进入校园"),

    /**
     * 出校门抄送通知提醒
     */
    PEOPLE_OUT_ACCESS("70","家长你好，您的孩子已经离开校园"),

    /**
     * 请假审核回推通知提醒-通过
     */
    APPROVAL_BACK_SEND("80", "您有一条新的请假审核通过通知,{username}通过"),

    /**
     * 请假审核回推通知提醒-驳回
     */
    APPROVAL_BACK_FAIL("90", "您有一条新的请假审核驳回通知,{username}驳回");


    @Getter
    @Setter
    private String code;

    @Getter
    @Setter
    private String value;

    MessageEnum(String code, String value) {
        this.code = code;
        this.value = value;
    }

    public static MessageEnum getValue(String code) {
        for (MessageEnum value : values()) {
            if (value.getCode().equals(code)) {
                return value;
            }
        }
        return null;
    }
}
