Spring Boot - Font Awesome OTS parsing error: Failed to convert

问题

Problem with Fonts not working correctly within a Spring Boot / Spring MVC Application.

The problem is that all of the font files show various errors such as below

Failed to decode downloaded font: http://localhost:8080/fonts/fontawesome-webfont.woff2?v=4.4.0
OTS parsing error: Failed to convert WOFF 2.0 font to SFNT

Failed to decode downloaded font: http://localhost:8080/fonts/fontawesome-webfont.woff?v=4.4.0
OTS parsing error: incorrect file size in WOFF header

Failed to decode downloaded font: http://localhost:8080/fonts/fontawesome-webfont.ttf?v=4.4.0
OTS parsing error: incorrect entrySelector for table directory

The issue is that Maven was filtering the font files and corrupting them.

    <resource>
        <directory>${project.basedir}/src/main/resources</directory>
        <filtering>true</filtering>
    </resource>

The fix was to make the following changes to the pom.xml

    <resource>
        <directory>${project.basedir}/src/main/resources</directory>
        <filtering>true</filtering>
        <excludes>
            <exclude>static/fonts/**</exclude>
        </excludes>
    </resource>

    <resource>
        <directory>${project.basedir}/src/main/resources</directory>
        <filtering>false</filtering>
        <includes>
            <include>static/fonts/**</include>
        </includes>
    </resource>

This change allows for the fonts to not be filtered during packaging.

Another way to do it is update the configuration of the maven-resources-plugin as follows:

<plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-resources-plugin</artifactId>
     <configuration>
          <nonFilteredFileExtensions>
               <nonFilteredFileExtension>ttf</nonFilteredFileExtension>
               <nonFilteredFileExtension>woff</nonFilteredFileExtension>
               <nonFilteredFileExtension>woff2</nonFilteredFileExtension>
          </nonFilteredFileExtensions>
     </configuration>
</plugin>

Maybe your file application.properties should be ignored some path like

security.ignored=/css/**,/js/**,/images/**,/font/**
