本文介绍了如何在SpringBoot项目中使用`@MapperScan`注解扫描DAO接口，并在pom.xml的build资源配置中指定包括.properties,.xml,.yml文件，以便正确加载配置。

解决办法：

1、给主类MarketGoodsApplication加注解 @MapperScan("com.fish.marketgoods.dao")
2、pom.xml文件的build节点下加入如下代码：

<resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                    <include>**/*.yml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                    <include>**/*.yml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
        </resources>
