- 1.引入依赖
- 2.mybatis-generator-config.xml插件配置文件
- 3.设置启动器并执行
事先准备：先把数据库的表都设计好
1.引入依赖
dependencies和plugin下，需要添加依赖和配置如下所示
<dependencies>
//....其他依赖
<dependency>
<groupId>org.mybatisgroupId>
<artifactId>mybatisartifactId>
<version>3.5.2version>

2.mybatis-generator-config.xml插件配置文件
主要有三个地方需要自行配置
- 数据库的相关配置 ：jdbcConnection标签下的内容 驱动类，连接，用户名密码
- 各类文件的生成位置配置：javaModelGenerator标签、sqlMapGenerator标签、sqlMapGenerator标签、javaClientGenerator标签下的内容，指定生成路径和包名
- 相关表的配置: table标签下的内容，指定需要生成的方法，enable开头的设置项
<generatorConfiguration>

<property name="suppressDate" value="true"/>

3.设置启动器并执行
新建一个启动器，如下图所示，入口为执行的绿色三角左侧，选择Edit Configurations…
加号、选择maven、设置名称和指令
mybatis-generator:generate -e
执行，执行时控制台信息如下，文件就自动生成了
