pom.xml檔案中新增：

<resources>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>*</include>
                    <include>*/*</include>
                </includes>
 

                <filtering>true</filtering>
            </resource>
            <!--mybatis 介面xml編譯到原始碼下面 -->
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include
 
>
                </includes>
            </resource>
        </resources>

重新build一下，OK！
