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; 
  
}
