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。
