找不到mapper映射文件，打开workspace工作空间以后，发现根本没有xml文件

解决办法：

修改pom文件，在其中加上如下代码：

 

<!-- 如果不添加此节点mybatis的mapper.xml文件都会被漏掉。 -->
	<build>
		<resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
        </resources>
