原因，xml文件没有编译到指定位置，需要在maven中指定

解决办法
maven 中 build标签中加入

<build>    <finalName>springmvc_mybatis</finalName>    <plugins>        <plugin>            <artifactId>maven-compiler-plugin</artifactId>            <version>2.3.2</version>            <configuration>                <source>1.8</source>                <target>1.8</target>            </configuration>        </plugin>    </plugins>    <resources>        <resource>            <directory>${basedir}/src/main/resources</directory>            <filtering>true</filtering>        </resource>        <resource>            <directory>src/main/java</directory>            <includes>                <include>**/*.properties</include>                <include>**/*.xml</include>            </includes>        </resource>    </resources></build>
