添加mybatis generator插件依赖

<plugins>
       
       <plugin>
          <groupId>org.mybatis.generator</groupId>
          <artifactId>mybatis-generator-maven-plugin</artifactId>
          <version>${mybatis.generator.version}</version>
          <configuration>
             <configurationFile>${basedir}/src/main/resources/generator.xml</configurationFile>
             <overwrite>true</overwrite>
             <verbose>true</verbose>
          </configuration>
          <dependencies>
             
             <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
                <version>${mysql.driver.version}</version>
             </dependency>
          </dependencies>
       </plugin>
    </plugins>
