报错原因:

IDEA是不会编译src的java目录的xml文件，所以在Mybatis的配置文件中找不到xml文件！需要人工配置

解决方案一:

将xxxMapper.xml放到Maven构建的resource目录下面。

解决方案二:

在Maven的pom文件的结尾，添加下面代码,意思是编译配置文件包括src/main/java目录：

    <build>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
        </resources>
    </build>

总之,就是要让idea编译到mapper文件!

成功:
