Mybatis-Plus

    1.在yml文件配置 枚举/枚举包 的路径

mybatis-plus:
  type-enums-package: com.demo.enums

    2.使用@EnumValue标记数据库值对应的属性

@Getter
public enum GenderEnum {
    @ApiModelProperty(value = "性别：默认-1=未知；0=女；1=男", allowableValues = "-1,0,1", example = "UNKNOWN")
    UNKNOWN(-1, "UNKNOWN"),
    @ApiModelProperty(value = "性别：默认-1=未知；0=女；1=男", allowableValues = "-1,0,1", example = "FEMALE")
    FEMALE(0, "FEMALE"),
    @ApiModelProperty(value = "性别：默认-1=未知；0=女；1=男", allowableValues = "-1,0,1", example = "MALE")
    MALE(1, "MALE");

    @JsonCreator
    GenderEnum(Integer code, String value) {
        this.code = code;
        this.value = value;
    }

    @EnumValue
    private final Integer code;
    @JsonValue
    private final String value;
}

 3.在类的属性声明上直接将字段类型标记为枚举类型，读取时将自动转换数据库值为枚举对象。

@Data
@TableName("test")
public class TestEntity {
    private Long uid;
    private GenderEnum gender;
 
}
