一、在resources目录下创建文件

generatorConfig.xml

<?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">

<generatorConfiguration>
    <properties resource="config.properties"/>

    <context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat">
        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>
        <plugin type="tk.mybatis.mapper.generator.MapperPlugin">
            <property name="mappers" value="tk.mybatis.mapper.common.Mapper"/>
            <property name="caseSensitive" value="true"/>
            <!--<property name="lombok" value="Getter,Setter,ToString"/>-->
        </plugin>

        <jdbcConnection driverClass="${jdbc.driverClass}"
                        connectionURL="${jdbc.url}"
                        userId="${jdbc.user}"
                        password="${jdbc.password}">
        </jdbcConnection>

        <!--实体-->
        <javaModelGenerator targetPackage="com.example.dao.entity.${entityName}"
                            targetProject="src/main/java"/>

        <!--mapper.xml-->
        <sqlMapGenerator targetPackage="com.example.dao.${moduleName}"
                         targetProject="src/main/resources"/>

        <!--mapper接口-->
        <javaClientGenerator targetPackage="com.example.dao.mapper.${moduleName}"
                             targetProject="src/main/java"
                             type="XMLMAPPER"/>

        <!--为哪张表生成代码-->
        <table tableName="${tableName}">
            <generatedKey column="id" sqlStatement="JDBC"/>
        </table>
    </context>
</generatorConfiguration>

 

config.properties

jdbc.driverClass=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/example_protection?nullCatalogMeansCurrent=true&serverTimezone=UTC&useUnicode=true&characterEncoding=UTF-8
jdbc.user=root
jdbc.password=root

moduleName=UserMapper
tableName=t_user
entityName=User

 

二、pom.xml中添加

 

<dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.11</version>
            <scope>test</scope>
        </dependency>

        <!--   &lt;!&ndash; https://mvnrepository.com/artifact/org.mybatis.generator/mybatis-generator-core &ndash;&gt;
           <dependency>
               <groupId>org.mybatis.generator</groupId>
               <artifactId>mybatis-generator-core</artifactId>
               <version>1.3.6</version>
           </dependency>
           &lt;!&ndash; 通用 Mapper &ndash;&gt;
           &lt;!&ndash; https://mvnrepository.com/artifact/tk.mybatis/mapper &ndash;&gt;
           <dependency>
               <groupId>tk.mybatis</groupId>
               <artifactId>mapper</artifactId>
               <version>4.0.0</version>
           </dependency>
           &lt;!&ndash; 如果你只需要用到通用 Mapper 中的插件,可以只引入 mapper-generator &ndash;&gt;
           &lt;!&ndash; 注意,这个包不需要和上面的 mapper 同时引入,mapper 中包含 generator &ndash;&gt;
           &lt;!&ndash; https://mvnrepository.com/artifact/tk.mybatis/mapper-generator &ndash;&gt;

               <version>1.0.0</version>
           </dependency>-->

        </dependency>

    </dependencies>

            </plugin>
