Logback未记录使用logger的异常.throwable,错误(消息)

Question

我有一点问题与Logback，我似乎不能理解是什么导致这个问题。每当我呼叫记录器。error(String message, Throwable t)， stacktrace本身不打印，打印的是消息。

输出:[06.02.2021 11:36:52] [Threadpool (Thread 0)] [ERROR]: An error occured while executing a command!(下面没有堆栈跟踪)'

我logback.xml:

<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<target>System.out</target>
<encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
<layout class="at.Xirado.Bean.Logging.Layout" />
</encoder>
</appender>

<root level="all">
<appender-ref ref="STDOUT" />
</root>
</configuration>

自定义布局类:

package at.Xirado.Bean.Logging;
import ch.qos.logback.classic.Level;
import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.core.CoreConstants;
import ch.qos.logback.core.LayoutBase;
import org.jline.utils.AttributedStringBuilder;
import org.jline.utils.AttributedStyle;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
public class Layout extends LayoutBase<ILoggingEvent> {
public String doLayout(ILoggingEvent event) {
StringBuffer sbuf = new StringBuffer(128);
LocalDateTime myDateObj = LocalDateTime.now();
DateTimeFormatter myFormatObj = DateTimeFormatter.ofPattern("dd.MM.yyyy HH:mm:ss");
String formattedDate = myDateObj.format(myFormatObj);
AttributedStringBuilder asb = new AttributedStringBuilder();
if(event.getLevel() == Level.ERROR)
{
asb.style(AttributedStyle.DEFAULT.foreground(222,23,56));
}else if(event.getLevel() == Level.WARN)
{
asb.style(AttributedStyle.DEFAULT.foreground(255,255,0));
}
asb.append("[").append(formattedDate).append("] [")
.append(event.getThreadName())
.append("] [")
.append(event.getLevel().levelStr.toUpperCase())
.append("]: ")
.append(event.getFormattedMessage());
asb.style(AttributedStyle.DEFAULT).append(CoreConstants.LINE_SEPARATOR);
sbuf.append(asb.toAnsi());
return sbuf.toString();
}
}

任何帮助都是感激的，谢谢:)

因为当日志级别为错误时，布局返回没有stacktrace

private static String getStackTrace(IThrowableProxy throwable, int maxStackTraceDepth) {
if(throwable==null) return null;
StringBuilder stackTraceSB = new StringBuilder(((ThrowableProxy)throwable).getThrowable().toString()+"n");
StackTraceElementProxy[] stackTraceElements = throwable.getStackTraceElementProxyArray();
for (int i = 0; i < stackTraceElements.length; i++) {
if (i >= maxStackTraceDepth) {
stackTraceSB.append("t").append("... " + (stackTraceElements.length - i) + " more");
break;
}
stackTraceSB.append("tat ").append(stackTraceElements[i].toString()).append("n");
}
return stackTraceSB.toString();
}
public String doLayout(ILoggingEvent event) {
StringBuffer sbuf = new StringBuffer(128);
//ignore other code
if(Level.ERROR.equals(event.getLevel())){
asb.append(getStackTrace(event.getThrowableProxy(),10));
}
return sbuf.toString();
}
