准确来讲，应该是maven项目使用Bootstrap时，出现
"Failed to decode downloaded font"和"OTS parsing error: Failed to convert WOFF 2.0 font to SFNT"
导致图标出不来的问题。
解决方案：
设置filter，font文件不需要filter，见下面示例：
<build>
<finalName>bootstrap in maven</finalName>
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
<excludes>
<exclude>static/fonts/**</exclude>
</excludes>
</resource>
<!-- fonts file cannot use filter as the data structure of byte file will be changed via filter -->
<resource>
<directory>src/main/resources</directory>
<filtering>false</filtering>
<includes>
<include>static/fonts/**</include>
</includes>
</resource>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include>
</includes>
</resource>
</resources>
...
</build>
原因：
上面的xml里也写了，因为经过maven的filter，会破坏font文件的二进制文件格式，到时前台解析出错。
