yml或者properties文件没有被扫描到，需要在pom文件中<build></build>添加如下内容来保证文件都能正常被扫描到并且加载成功。
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.yml</include>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.yml</include>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>如果只用到MyBatis可以在pom文件中<build></build>添加如下内容：
<build>
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include>
</includes>
</resource>
</resources>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
