What scenario will encounter this problem?

In general, it can be said that in most cases, if the synthesis of images with text is not involved, the font file may not be used. When this file is needed, we will put our static resource file in the resource directory, and then use the program to read the static resources. This is a normal practice. This is no problem, However, you may find that it is normal to run unit tests without error, and the effect is in line with your expectations. However, when you package and compile and run locally through Java – jar xxx.jar, an error will be reported:

reason

The font library font referenced by the Maven project of the springboot project passes through the Maven filter, which will destroy the binary file format of the font file

Solution:

Add the following configuration in pom.xml file:

<build>
  <plugins> 
    <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>
  </plugins>
</build>

Then use MVN clean install to package and compile again, and then use Java – jar xxx.jar to avoid errors.
