出现的原因之一：是因为你的mapper接口和mapper.xml文件没有进行绑定到，springboot没有扫描到.xml文件

解决：（在pom.xml的build节点中插入）

<resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/java/resources</directory>
                <includes>
                    <include>**/*.*</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/java/bookstore</directory>
                <targetPath>META-INF/resources</targetPath>
                <includes>
                    <include>**/*.*</include>
                </includes>
            </resource>
        </resources>
