＃使用方法：使用generator插件可以帮助我们生成model，mapper等文件，因而简化开发流程，加快开发速度，以下是使用方法：

\#\#在pom.xml中添加插件

<commentGenerator>
            
            <property name="suppressDate" value="true"/>
            
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
    
        
        <jdbcConnection
                driverClass="${spring.datasource.driver-class-name}"
                connectionURL="${spring.datasource.url}"
                userId="${spring.datasource.username}"
                password="${spring.datasource.password}">
        </jdbcConnection>
    
        
        
        <javaTypeResolver>
            
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>
    
        
        <javaModelGenerator targetPackage="com.example.myproject.model" targetProject="src/main/java">
            
            <property name="trimStrings" value="true" />
            
            <property name="enableSubPackages" value="false" />
        </javaModelGenerator>
    
        
        <sqlMapGenerator targetPackage="mapper"  targetProject="src/main/resources">
            
            <property name="enableSubPackages" value="false" />
        </sqlMapGenerator>
    
        
        <javaClientGenerator targetPackage="com.example.myproject.mapper" targetProject="src/main/java" type="XMLMAPPER">
            
            <property name="enableSubPackages" value="false" />
        </javaClientGenerator>
    
        
        
    
        <table schema="user" tableName="user"
        domainObjectName="User" enableCountByExample="false"
        enableDeleteByExample="false" enableSelectByExample="false"
        enableUpdateByExample="false">
        </table>
    
        
        
        
        
        
    
        
        
        
        
        
    
        
        
        
        
        
    
    </context>

\`\`\`

在application.properties中添加以下部分  
一定要注意jdbc.location中的路径一定不要包含中文  
\#数据库设置

spring.datasource.url=jdbc:mysql://localhost:3306/user?characterEncoding=UTF-8&useUnicode=true&useSSL=false
    spring.datasource.username=root
    spring.datasource.password=123456
    spring.datasource.driver-class-name=com.mysql.jdbc.Driver

### Mybatis 配置 ###

mybatis.typeAliasesPackage=com.example.myproject.domain
    mybatis.mapperLocations=classpath:mapper/*.xml
    
    jdbc.location=F:/MyDownloads/mysql-connector-java-5.1.39-bin.jar

最后点击run->edit configuration->点击+号新建一个maven

点击apply,ok,然后点击run generator运行即可（一定要自己提前建立好对应的文件夹）
