### 解决方法： ###

1.首先看一下你的UserMapper.xml文件是不是放在src目录下，如果是那么报错的原因就是：maven是不会去编译src目录下的xml文件

2.需要在项目的pom.xml文件中添加这一段代码即可。

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