SpringBoot引入MyBatisGenerator

1.引入插件

<plugin><groupId>org.mybatis.generator</groupId><artifactId>mybatis-generator-maven-plugin</artifactId><version>1.3.5</version><configuration><!--generator配置文件所在位置--><configurationFile>src/main/resources/mybatis-generator/generatorConfig.xml</configurationFile><overwrite>true</overwrite><verbose>true</verbose></configuration><dependencies><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.33</version></dependency></dependencies></plugin>

2.添加generator.xml并修改

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfigurationPUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN""http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<!-- 配置生成器 -->
<generatorConfiguration><!-- 一个数据库一个context --><context id="MysqlTables" targetRuntime="MyBatis3Simple" defaultModelType="flat"><!--去除注释--><commentGenerator><property name="suppressDate" value="true"/><property name="suppressAllComments" value="true" /></commentGenerator><!--数据库链接信息--><jdbcConnection driverClass="com.mysql.jdbc.Driver"connectionURL="jdbc:mysql://127.0.0.1:3306/mycnblog?serverTimezone=Asia/Shanghai&amp;nullCatalogMeansCurrent=true"userId="root"password="root"></jdbcConnection><!-- 生成实体类 --><javaModelGenerator targetPackage="com.example.demo.generator.model" targetProject="src/main/java" ><property name="enableSubPackages" value="false"/><property name="trimStrings" value="true"/></javaModelGenerator><!-- 生成mapxml文件 --><sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources/generator" ><property name="enableSubPackages" value="false" /></sqlMapGenerator><!-- 生成mapxml对应client，也就是接口dao --><javaClientGenerator targetPackage="com.example.demo.generator.mapper" targetProject="src/main/java" type="XMLMAPPER" ><property name="enableSubPackages" value="false" /></javaClientGenerator><!-- table可以有多个,每个数据库中的表都可以写一个table，tableName表示要匹配的数据库表,也可以在tableName属性中通过使用%通配符来匹配所有数据库表,只有匹配的表才会自动生成文件 --><table tableName="userinfo"><property name="useActualColumnNames" value="false" /><!-- 数据库表主键 --><generatedKey column="id" sqlStatement="Mysql" identity="true" /></table><table tableName="articleinfo"><property name="useActualColumnNames" value="false" /><!-- 数据库表主键 --><generatedKey column="id" sqlStatement="Mysql" identity="true" /></table></context>
</generatorConfiguration>
