Java枚举模板（Int类型枚举、Str类型枚举）

Int类型枚举

/**
 * Int类型枚举
 */
public enum IntEnum {

    //
    RED(1, "红色"),
    GREEN(2, "绿色"),
    YELLOW(3, "黄色"),
    ;

    private final Integer code;

    private final String name;

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

    public Integer getCode() {
        return code;
    }

    public String getName() {
        return name;
    }

    private static final Map<Integer, Object> codeMap = new HashMap<>();

    static {
        for (IntEnum e : IntEnum.values()) {
            codeMap.put(e.getCode(), e);
        }
    }

    /**
     * 通过code获取对应枚举
     *
     * @param code
     * @return
     */
    public static IntEnum get(Integer code) {
        return (IntEnum) codeMap.get(code);
    }

    /**
     * 通过code获取对应枚举name
     *
     * @param code
     * @return
     */
    public static String getName(Integer code) {
        IntEnum e = get(code);
        return e == null ? "" : e.getName();
    }

}

Str类型枚举

/**
 * Str类型枚举
 */
public enum StrEnum {

    //
    RED("red", "红色"),
    GREEN("green", "绿色"),
    YELLOW("yellow", "黄色"),
    ;

    private final String code;

    private final String name;

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

    public String getCode() {
        return code;
    }

    public String getName() {
        return name;
    }

    private static final Map<String, Object> codeMap = new HashMap<>();

    static {
        for (StrEnum e : StrEnum.values()) {
            codeMap.put(e.getCode(), e);
        }
    }

    /**
     * 通过code获取对应枚举
     *
     * @param code
     * @return
     */
    public static StrEnum get(String code) {
        return (StrEnum) codeMap.get(code);
    }

    /**
     * 通过code获取对应枚举name
     *
     * @param code
     * @return
     */
    public static String getName(String code) {
        StrEnum e = get(code);
        return e == null ? "" : e.getName();
    }

}
