第一步： pom文件配置黃線的部分是所要配置的java

                <artifactId>spring-boot-maven-plugin</artifactId>

            <plugin>

                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <dependencies>

                </configuration>
            </plugin>
        </plugins>
    </build>


</project>

第二步：在resource文件夾下建立 mybatis-generator.xml 文件mysql

<?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>
    <context id="DB2Tables"    targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!--數據庫連接地址帳號密碼-->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://rm-uf6qe0894f7hv8977o.mysql.rds.aliyuncs.com/sell"
                        userId="root"
                        password="liuxiaoming_123" >
        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!--生成Model類存放位置-->
        <javaModelGenerator targetPackage="com.payease.dataobject" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>
        <!--生成映射文件存放位置-->
        <sqlMapGenerator targetPackage="com.payease.dataobject.mapper" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>
        <!--生成Dao類存放位置-->
        <!-- 客戶端代碼，生成易於使用的針對Model對象和XML配置文件 的代碼
                type="ANNOTATEDMAPPER",生成Java Model 和基於註解的Mapper對象
                type="MIXEDMAPPER",生成基於註解的Java Model 和相應的Mapper對象
                type="XMLMAPPER",生成SQLMap XML文件和獨立的Mapper接口
        -->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.payease.dataobject.dao" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>
        <!--生成對應表及類名-->
        <table tableName="product_category"
               domainObjectName="ProductCategory">
           <!--    enableCountByExample="false"
               enableUpdateByExample="false"
               enableDeleteByExample="false"
               enableSelectByExample="false"
               selectByExampleQueryId="false"-->
            <generatedKey column="id" sqlStatement="JDBC" identity="true"/>
        </table>
    </context>
</generatorConfiguration>

第三步：雙擊mybatis-generator:generategit

第五步：在src/main/java/com/payease/ 文件夾下的 dataobject 、dataobject/dao 、dataobject/mapper生成相應的文件github

注：springboot 默認的mapper.xml映射文件掃描的位置在 resources/mapper文件夾下 web

若不在此文件夾下，請在pom文件中進行相應的配置redis

    <build>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
            </resource>
        </resources>
        <finalName>wallet-orm</finalName>
    </build>
