SpringBoot整合MybatisPlus基本的增删改查，保姆级教程( 二 )

SpringBoot

【SpringBoot整合MybatisPlus基本的增删改查，保姆级教程】@TableField 是mybatisplus中的一个注解，后面会讲解到的 。
基础实体类创建好了，接着我们把剩下的两个实体类也一同创建吧 。
5|2SysDictType实体类package com.didiplus.modules.sys.domain;import com.didiplus.common.base.BaseDomain;import com.didiplus.common.base.ValidGroup;import io.swagger.annotations.ApiModel;import io.swagger.annotations.ApiModelProperty;import lombok.Data;import javax.validation.constraints.*;/** * Author: didiplus * Email: 972479352@qq.com * CreateTime: 2022/4/25 * Desc: 字典类型领域模型 */@Data@ApiModel(value = https://www.isolves.com/it/cxkf/jiagou/2022-05-05/"字典类型")public class SysDictType extends BaseDomain {/*** 标识*/@Null(groups = ValidGroup.Crud.Create.class)@NotNull(groups = ValidGroup.Crud.Update.class,message = "字典ID不能为空")@ApiModelProperty("ID")private String id;/*** 字典名称*/@NotBlank(message = "字典名称必填项")@ApiModelProperty(value = "字典名称",example = "用户ID")private String typeName;/*** 字典类型*/@NotBlank(message = "字典编码不能为空")@ApiModelProperty(value = "字典编码")private String typeCode;/*** 字典描述*/@ApiModelProperty(value = "字典描述")private String description;/*** 字典可用状态*/@NotBlank(message = "字典状态不能为空")@ApiModelProperty(value = "字典状态")private Boolean enable;}5|3SysDictData实体类package com.didiplus.modules.sys.domain;import com.baomidou.mybatisplus.annotation.TableField;import com.didiplus.common.base.BaseDomain;import com.didiplus.common.base.ValidGroup;import io.swagger.annotations.ApiModelProperty;import lombok.Data;import javax.validation.constraints.NotBlank;import javax.validation.constraints.NotNull;import javax.validation.constraints.Null;/** * Author: didiplus * Email: 972479352@qq.com * CreateTime: 2022/4/29 * Desc: 字典值领域模型 */@Datapublic class SysDictData extends BaseDomain {/*** id 编号*/@Null(groups = ValidGroup.Crud.Create.class)@NotNull(groups = ValidGroup.Crud.Update.class,message = "字典数据ID不能为空")@ApiModelProperty("ID")@TableField(value = https://www.isolves.com/it/cxkf/jiagou/2022-05-05/"data_id")private String dataId;/*** 字典显示*/@NotBlank(message = "字典数据名称必填项")@ApiModelProperty(value = "字典数据名称")private String dataLabel;/*** 字典值*/@NotBlank(message = "字典数据值不能为空")@ApiModelProperty(value = "字典数据值")private String dataValue;/*** 字典类型*/@ApiModelProperty(value = "字典编码")@NotBlank(message = "字典数据值不能为空")private String typeCode;/*** 是否为默认*/@ApiModelProperty(value = "字典编码")@NotBlank(message = "字典数据值不能为空")private String isDefault;/*** 是否启用*/@NotBlank(message = "字典状态不能为空")@ApiModelProperty(value = "字典数据状态")private Boolean enable;}6|0创建DAO继承MybatisPlus增强接口为两个实体类中分别添加DAO继承MybatisPlus增强接口，这样就可以集成了增删改查的功能了 。
