logstash-logback-encoder 在一个字符串中显示堆栈跟踪的输出，例如

"stack_trace": "java.lang.RuntimeException: null\n\tat com.ideasforsharing.demo.controllers.SleuthController.helloSleuth(SleuthController.java:24)\n\tat sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)\n\tat sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)\n"

这很难阅读。我如何格式化堆栈跟踪的显示以在多行上显示它，也许使用 json 数组？

"stack_trace" : [
    "java.lang.RuntimeException: null",
      "com.ideasforsharing.demo.controllers.SleuthController.helloSleuth(SleuthController.java:24)",
        "at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)",
        "at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)"
]

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>

班级看起来像

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);
    }
  }
}

给出格式的输出
