"Unable to read TLD from JAR file" when run spring boot app on heroku

Question

I wrote an springboot app running at Heroku. When I run locally with maven spring-boot:run everthing is ok.

But when I deploy the app to Heroku, the page show error:

There was an unexpected error (type=Internal Server Error, status=500).
/WEB-INF/jsp/login.jsp (line: 3, column: 0) /WEB-INF/jsp/common.jsp (line: 3, column: 64) Unable to read TLD "META-INF/spring.tld" from JAR file "jar:file:/app/target/slog-1.0-SNAPSHOT.jar!/lib/spring-webmvc-4.0.7.RELEASE.jar": java.io.IOException: Unable to open root Jar file 'jar:file:/app/target/slog-1.0-SNAPSHOT.jar'

And I run the jar locally with "java -jar target/*.jar" have the same error.

this is my pom.xml file:

There is a known limitation in Spring Boot and an open issue related to using JSPs with embedded containers. Long story short, it's not currently supported. However, the Spring Boot reference documentation links to a GitHub example project they claim gets it working.

I found a better way to deploy spring boot app to heroku.

first change maven package to war.

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <version>2.4</version>
            <configuration>
                <warSourceExcludes>WEB-INF/lib/log4j-${log4j.version}.jar</warSourceExcludes>
            </configuration>
        </plugin>

then change Procfile to web: java $JAVA_OPTS -jar target/*.war .

solved :D.
