我做了某事
<provider class="com.ac.log.CustomStackTraceJsonProvider">
<throwableConverter class="net.logstash.logback.stacktrace.ShortenedThrowableConverter">
<maxDepthPerThrowable>full</maxDepthPerThrowable>
<maxLength>full</maxLength>
<shortenedClassNameLength>20</shortenedClassNameLength>
<exclusions>${STE_EXCLUSIONS}</exclusions>
<rootCauseFirst>true</rootCauseFirst>
</throwableConverter>
</provider>
这个类看起来像
import java.io.IOException;
import java.util.LinkedHashMap;
import java.util.Map;
import com.fasterxml.jackson.core.JsonGenerator;
import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.classic.spi.IThrowableProxy;
import net.logstash.logback.composite.JsonWritingUtils;
import net.logstash.logback.composite.loggingevent.StackTraceJsonProvider;
public class CustomStackTraceJsonProvider extends StackTraceJsonProvider {
public CustomStackTraceJsonProvider() {
super();
}
@Override
public void writeTo(JsonGenerator generator, ILoggingEvent event) throws IOException {
IThrowableProxy throwableProxy = event.getThrowableProxy();
if (throwableProxy != null) {
String msg = getThrowableConverter().convert(event);
String[] lines = msg.split("\\n\\t");
Map<String, String> lineMap = new LinkedHashMap<>();
for(int i = 0; i < lines.length; i++){
lineMap.put(String.valueOf(i+1), lines[i]);
}
JsonWritingUtils.writeMapStringFields(generator, getFieldName(), lineMap);
}
}
}
输出格式为
