Spring Boot + Bootstrap 出现"Failed to decode downloaded font"和"OTS parsing error: Failed to convert WOFF 2.0 font to SFNT"

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。
