原因可能是IDEA在打包的时候，把这字体给过滤拦截了，可以在pom.xml进行配置：
<resources> <resource> <directory>src/main/resources</directory> <filtering>true</filtering> <excludes> <exclude>**/*.woff</exclude> <exclude>**/*.woff2</exclude> <exclude>**/*.ttf</exclude> </excludes> </resource> <resource> <directory>src/main/resources</directory> <filtering>false</filtering> <includes> <include>**/*.woff</include> <include>**/*.woff2</include> <include>**/*.ttf</include> </includes> </resource> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> </resource> </resources>
