1.建立列舉類

@Getter
public enum ProductsStatusEnum {
    UP(0, "在架"),
    DOWN(1, "下架");

    private Integer code;
    private String message;

    ProductsStatusEnum(Integer code, String message) {
        this.code = code;

        this.message = message;
    }
}

2.應用的地方

System.out.println(ProductsStatusEnum.UP.getCode());
System.out.println(ProductsStatusEnum.UP.getMessage());
