1、Maven專案

2、配置generatorConfig.xml檔案

3、在pom.xml中配置外掛

　　2、generatorConfig.xml檔案資訊

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration

<generatorConfiguration>
    <context id="default" targetRuntime="MyBatis3Simple">

            <property name="suppressDate" value="true" />
            <!--去除註釋-->
            <property name="suppressAllComments"
 
 value="true"/>
        </commentGenerator>

        <!--jdbc的資料庫連線-->
        <jdbcConnection driverClass="org.mariadb.jdbc.Driver"
                        connectionURL="jdbc:mariadb://localhost:3306/data_test"

        </jdbcConnection

        <!-- Model模型生成器
            targetPackage -> 指定生成的model生成所在的包名
            targetProject -> 指定在該專案下所在的路徑
        -->
        <javaModelGenerator targetPackage="com.oukele.model" targetProject="src/main/java">
            <!-- 是否對類CHAR型別的列的資料進行trim操作 -->

        </javaModelGenerator>
        <!--Mapper對映檔案生成所在的目錄 為每一個數據庫的表生成對應的SqlMap檔案-->
        <sqlMapGenerator targetPackage="DynamicSql.xml"  targetProject="src/main/resources"/>

        <!-- tableName 表名  % -> 全部表   -->
        <table tableName="%">
            <generatedKey column="id" sqlStatement="Mysql"/>
        </table>

    </context>
</generatorConfiguration>

　　3、在pom.xml檔案中配置外掛
