Problem Description
After packaging SpringBoot into a jar file, static resources become inaccessible.
Solution
Add resource configuration in pom.xml:
<build>
<resources>
<resource>
<!-- Copy jsp files to META-INF directory when packaging-->
<!-- Specify which directory's resource files the resources plugin should handle -->
<directory>src/main/resources</directory>
<!--Must be placed here to be accessible-->
<targetPath>META-INF/resources</targetPath>
<includes>
<include>**/**</include>
</includes>
</resource>
</resources>
</build>
