Mybatis逆向工程

1.将插件放入到porm.xml中：

 <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.5</version>
                <executions>
                    <execution>
                        <id>Generate MyBatis Artifacts</id>
                        <goals>
                            <goal>generate</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>
            </plugin>

2. 编辑generatorConfig.xml:

这个文件中的数据需要根据自己的数据库修改！

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<!-- 配置Run As Maven build : Goals 参数 : mybatis-generator:generate -Dmybatis.generator.overwrite=true -->
<!-- 配置 tableName,使用 Run As Maven build 生成 dao model 层 -->
<generatorConfiguration>

    <!--数据库驱动包路径 -->
    <classPathEntry
            location="C:\Users\S\.m2\repository\mysql\mysql-connector-java\8.0.16\mysql-connector-java-8.0.16.jar"/>
    <context id="DB2Tables" targetRuntime="MyBatis3">
        <!--关闭注释 -->
        <commentGenerator>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!--数据库连接信息 -->
        <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/frame?characterEncoding=utf-8&amp;serverTimezone=UTC"
                        userId="root" password="lucas">
        </jdbcConnection>
        <!--生成的model 包路径 -->
        <javaModelGenerator targetPackage="com.zpark.neimin.first.model"
                            targetProject="src/main/java">
            <property name="enableSubPackages" value="ture"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>
        <!--生成xml mapper文件 路径 -->
        <sqlMapGenerator targetPackage="mapper"
                         targetProject="src/main/resources">
            <property name="enableSubPackages" value="ture"/>
        </sqlMapGenerator>
        <!-- 生成的Dao接口 的包路径 -->
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="com.zpark.neimin.first.dao"
                             targetProject="src/main/java">
            <property name="enableSubPackages" value="ture"/>
        </javaClientGenerator>
        <!--对应数据库表名，多个表，请复制指定 -->
        <!--生成对应表及类名-->
      <!-- <table tableName="school" domainObjectName="School"></table>-->

      <table tableName="aaa" domainObjectName="aaa"></table>


<!--       <table tableName="student" domainObjectName="Student"></table>-->



    </context>
</generatorConfiguration>
