Can the stacktrace in Spring Boot be reduced?

Is it possible to reduce the stacktrace from an exception down to ignore Springs stack?

When a method of mine throws a IllegalArgumentException (as intended) and I log the message and stacktrace in log4j, I get an entire log of Springs stack as well while all I really need for my own exceptions thrown is the relevant part in the code that is actually in play.

For example the below stack should be reduced to 8 lines, ignoring the org.springframework and forward.

Also, of course, when Spring throws an exception on its own, I would expect it to show its stacktrace.

There's a Log4J add-on that can filter the stack trace. With the custom layout on the classpath, you can then configure the elements to filter out in your config:

<appender name="console" class="org.apache.log4j.ConsoleAppender">
    <layout class="it.openutils.log4j.FilteredPatternLayout">
        <param name="ConversionPattern" value="%-5p  %c %F(%M:%L) %d{dd.MM.yyyy HH:mm:ss}  %m%n" />
        <param name="Filter" value="org.apache.catalina" />
        <param name="Filter" value="org.apache.tomcat" />
        <param name="Filter" value="org.apache.coyote" />
        <param name="Filter" value="org.myapp.web.filters" />
        <param name="Filter" value="com.opensymphony.module.sitemesh.filter" />
        <param name="Filter" value="sun.reflect" />
        <param name="Filter" value="javax.servlet.http" />
    </layout>
</appender>

Google's Guava library has some nice utility methods in it's Throwables API. For your particular case, I think getRootCause(Throwable) or getCausalChain(Throwable) would work well.

Causal Chain Guava makes it somewhat simpler to study the causal chain of an exception, providing three useful methods whose signatures are self-explanatory:

Throwable getRootCause(Throwable)
List<Throwable> getCausalChain(Throwable)
String getStackTraceAsString(Throwable)
