SpringBoot 引⼊MybatisGenerator

1. 引入插件

<plugin>
    <groupId>org.mybatis.generatorgroupId>
    <artifactId>mybatis-generator-maven-pluginartifactId>
    <version>1.3.5version>
    <configuration>
        
        <configurationFile>src/main/resources/mybatis-generator/generatorConfi
            g.xmlconfigurationFile>
        <overwrite>trueoverwrite>
        <verbose>trueverbose>
    configuration>
    <dependencies>
        <dependency>
            <groupId>mysqlgroupId>
            <artifactId>mysql-connector-javaartifactId>
            <version>8.0.33version>
        dependency>
    dependencies>
plugin>

2. 添加generator.xml并修改

DOCTYPE generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<generatorConfiguration>
    
    <context id="MysqlTables" targetRuntime="MyBatis3Simple" defaultModelT ype="flat">
        
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <property name="suppressAllComments" value="true" />
        commentGenerator>
        
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://127.0.0.1:3306/java_blog_spring?serverTimezone=Asia/Shanghai&nullCatalogMeansCurrent=true"
                        userId="root"
                        password="root">
        jdbcConnection>
        
        <javaModelGenerator targetPackage="com.example.demo.model" targetP
                            roject="src/main/java" >
            <property name="enableSubPackages" value="false"/>
            <property name="trimStrings" value="true"/>
        javaModelGenerator>
        
        <sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources" >
            <property name="enableSubPackages" value="false" />
        sqlMapGenerator>
        
        <javaClientGenerator targetPackage="com.example.demo.mapper" targe 
                             tProject="src/main/java" type="XMLMAPPER" >
            <property name="enableSubPackages" value="false" />
        javaClientGenerator>
        
        <table tableName="user">
            <property name="useActualColumnNames" value="false" />
            
            <generatedKey column="id" sqlStatement="Mysql" identity="true"
            />
        table>
    context>
