**mybatis-generator生成代码：**

*  导入jar包

            </dependency>
        <build>
            
            <plugins>

                </plugin>
            </plugins>
        </build>
    
    </project>

*  配置generatorConfig.xml【用于配置代码生成位置等信息】

            </javaModelGenerator>
            
            <sqlMapGenerator targetPackage="cn.itsource.mybatis_generator.mapper" targetProject="src\main\resources">

            <table tableName="user" domainObjectName="User">
                <generatedKey column="id" sqlStatement="MySql" />
            </table>
        </context>
    </generatorConfiguration>
