Spring Boot 中的 stacktrace 可以减少吗？

Question

是否可以从异常减少堆栈跟踪以忽略 Springs 堆栈？

当我的一个方法抛出 IllegalArgumentException（按预期）并且我在 log4j 中记录消息和堆栈跟踪时，我也会得到 Springs 堆栈的完整日志，而我真正需要的只是我自己抛出的异常是代码中的相关部分实际上是在玩。

例如，下面的堆栈应该减少到 8 行，忽略 org.springframework 和向前。

此外，当然，当 Spring 自己抛出异常时，我希望它显示其堆栈跟踪。

有一个Log4J 插件可以过滤堆栈跟踪。 使用类路径上的自定义布局，您可以配置元素以在您的配置中过滤掉：

<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 的Guava库在它的Throwables API 中有一些不错的实用方法。 对于您的特定情况，我认为getRootCause(Throwable)或getCausalChain(Throwable)会很好用。

Causal Chain Guava 提供了三种有用的方法，它们的签名是不言自明的：

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