  1. 外掛匯入; pom檔案引入mybatis-generator-maven-plugin 
        <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <configuration> <!-- generator 工具配置檔案的位置 -->
                    <configurationFile>${basedir}/src/main/resources/mybatisGenerator/generatorConfig.xml</configurationFile>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>5.1.16</version>
                    </dependency>
                </dependencies>
    </plugin>
  2. generatorConfig.xml 配置 
    <?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="mybatisGenerator/mybatisGenerator.properties"/>

    <context id="lego" targetRuntime="MyBatis3Simple" defaultModelType="flat">

        <!-- 註釋 -->
        <commentGenerator >
            <!-- 是否取消註釋 -->
            <property name="suppressAllComments" value="false"/>
            <!-- 是否生成註釋代時間戳-->
            <property name="suppressDate" value="true" />
        </commentGenerator>

        <!--資料庫連線資訊-->
        <jdbcConnection driverClass="${jdbc.driverClass}" connectionURL="${jdbc.connectionURL}"
                        userId="${jdbc.userId}" password="${jdbc.password}">
        </jdbcConnection>

        <!--型別轉換-->
        <javaTypeResolver >
            <!-- 是否使用bigDecimal， false可自動轉化以下型別（Long, Integer, Short, etc.） -->
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <!-- 生成實體類地址 -->
        <javaModelGenerator targetPackage="${package.do}" targetProject="src/main/java">
            <property name="enableSubPackages" value="false" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <!--生成mapper-->
        <sqlMapGenerator targetPackage="${package.mapper}"  targetProject="src/main/resources">
            <property name="enableSubPackages" value="false" />
        </sqlMapGenerator>

        <!--dao介面-->
        <javaClientGenerator type="XMLMAPPER" targetPackage="${package.dao}"  targetProject="src/main/java">
            <property name="enableSubPackages" value="false" />
        </javaClientGenerator>

        <table tableName="lego_user" domainObjectName="UserDO" >
            <!-- 資料庫表主鍵 -->
            <generatedKey column="id" sqlStatement="select last_insert_id()" identity="true" />
        </table>

    </context>
</generatorConfiguration>
  3. generatorConfig.properties 配置（解耦和 ，可忽略） 
    #mysql
jdbc.driverClass=com.mysql.jdbc.Driver

#lego
jdbc.connectionURL=jdbc:mysql://localhost:3306/lego?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf8
jdbc.userId=root
jdbc.password=123456

#package
package.do=com.zhangweinan.dao.objects
package.dao=com.zhangweinan.dao
package.mapper=mapper

     

　　　　SpringBoot環境下對映關係配置

  1. application.properties檔案新增配置
    # mybatis
mybatis.mapper-locations=classpath:mapper/*.xml
  2. SpringBoot Starter啟動類新增註解MapperScan 
    @SpringBootApplication
@MapperScan("com.zhangweinan.dao")
public class Starter {

    public static void main(String[] args) {
        SpringApplication.run(Starter.class, args);
    }

}

     

    tips：mysql-connector-java jar 與 mybatis-generator-maven-plugin 外掛 可能會存在衝突問題，因此選擇合適的version很重要。配置1中親測可用
