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：

 1 <build>
 2         <finalName>bootstrap in maven</finalName>
 3         <resources>
 4             <resource>
 5                 <directory>src/main/resources</directory>
 6                 <filtering>true</filtering>
 7                 <excludes>  
 8                     <exclude>static/fonts/**</exclude>  
 9                 </excludes>  
10             </resource>
11             <!-- fonts file cannot use filter as the data structure of byte file will be changed via filter -->
12             <resource>  
13                 <directory>src/main/resources</directory>  
14                 <filtering>false</filtering>  
15                 <includes>  
16                     <include>static/fonts/**</include>  
17                 </includes>  
18             </resource>  
19             <resource>
20                 <directory>src/main/java</directory>
21                 <includes>
22                     <include>**/*.xml</include>
23                 </includes>
24             </resource>
25         </resources>
26 ...
27 </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。
