Let's start coding

建表语句

create table t_consume_type
(
    id          int auto_increment
        primary key,
    type_name   varchar(100)     null,

create table t_user_group

        primary key,
    group_id    int              null,
    group_name  varchar(100)     null,
    is_delete   char default '0' null comment '0正常 1删除',
    create_date datetime         null,
    update_time datetime         null,
    need_invite char default '0' null comment '邀请码  0不需要，1需要',
    invite_code varchar(50)      null comment '邀请码'
)
    charset = utf8;

create table t_invite_code

    create_date  datetime                    null
);

create table t_user
(
    id                   int auto_increment
        primary key,
    user_id              varchar(30)      not null comment '用户编号',
    group_id             int              null comment '分组id',
    user_type            char default '0' null comment '用户类型：0普通，1管理员',
    user_name            varchar(100)     null comment '用户名称',
    nick_name            varchar(100)     null comment '昵称',
    mobile               varchar(20)      null comment '手机号码',

    settle_status char              default '0'  null comment '是否已经结算，0否，1是'
);

新建springboot项目，按常规选择web、数据库连接等需要的依赖配置好pom文件
2.1. 进入mybatis generator官网找到Running MyBatis Generator With Maven

2.2. 选择maven这种方式。然后把代码复制到pom文件的插件配置里面去。

           <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.7</version>
                <configuration>
                    <overwrite>true</overwrite>
                </configuration>
            </plugin>

配置generatorConfig.xml

<?xml version="1.0" encoding="UTF-8"?>

       "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

       </javaModelGenerator>

       <sqlMapGenerator targetPackage="mappers" targetProject="src/main/resources">

       </sqlMapGenerator>

       <javaClientGenerator type="XMLMAPPER" targetPackage="com.ycj.mall.mapper" targetProject="src/main/java">

       <table tableName="t_user_pay" domainObjectName="UserPay" enableCountByExample="false"
              enableDeleteByExample="false" enableSelectByExample="false" enableUpdateByExample="false"/>
   </context>
</generatorConfiguration>

在控制台执行构建命令

mvn mybatis-generator:generate

查看结果
自动生成了dao、sql、xml、实体类

一般配置已经oh了，更高级的可以看官方文档做修改

最后附上pom文件配置
