Logback - filtering stack trace
提问by viniolli
I'm using logback for logging and i found some problem with filtering stack trace. I hava a structure like this:
我正在使用 logback 进行日志记录，但发现过滤堆栈跟踪存在一些问题。我有这样的结构：
public class Main {
static final Logger logger = (Logger) LoggerFactory.getLogger(Main.class);
public static void main(String[] args) {
logger.debug("Start");
MyObject1 loggingElement = new MyObject1();
loggingElement.logg();
logger.debug("End");
}
}
public class MyObject1 {
public MyObject2 obj;
static final Logger logger = (Logger) LoggerFactory.getLogger(MyObject1.class);
public MyObject1() {
obj = new MyObject2();
}
public void logg() {
obj.loggError();
}
}
public class MyObject2 {
static final Logger logger = (Logger) LoggerFactory.getLogger(MyObject2.class);
public void loggError() {
logger.error("Error info", new Throwable("Error"));
}
}
and configuration xml like this:
和配置xml是这样的：
<property name="mask"
value="MyObject2"/>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{HH:mm:ss} | %level | %-4thread | %-21logger | %m%n
</pattern>
</encoder>
</appender>
<root level="${root.level:-TRACE}">
<appender-ref ref="STDOUT" />
</root>
When i run the main method i get output like this:
当我运行 main 方法时，我得到如下输出：
12:29:35 | DEBUG | main | com.logging.Main | Start
12:29:35 | ERROR | main | com.logging.MyObject2 | Error info
java.lang.Throwable: Error
at com.logging.MyObject2.loggError(MyObject2.java:11) [bin/:na]
at com.logging.MyObject1.logg(MyObject1.java:17) [bin/:na]
at com.logging.Main.main(Main.java:14) [bin/:na]
12:29:35 | DEBUG | main | com.logging.Main | End
i would like to remove line with 'MyObject1' in it and leave rest of stack trace untouched just like int this example: http://java.dzone.com/articles/filtering-stack-trace-hell
我想删除其中包含“MyObject1”的行，并像本例中的 int 一样保留其余的堆栈跟踪：http: //java.dzone.com/articles/filtering-stack-trace-hell
i tried to change configuration of logback
我试图改变 logback 的配置
<pattern>%d{HH:mm:ss} | %level | %-4thread | %-21logger | %m%n%ex{full,${mask}}
</pattern>
doesn't work at all
根本不起作用
<pattern>%d{HH:mm:ss} | %level | %-4thread | %-21logger | %m%n%eXe{full,${mask}}
</pattern>
removes whole stack trace(not solution for me)
删除整个堆栈跟踪（不是我的解决方案）
Anyone knows anything that could help?
任何人都知道有什么可以帮助的吗？

This capability has been included in Logback Classic as of version 1.1.3. It seems to apply to the following Conversion Words of PatternLayout:
从版本 1.1.3开始，此功能已包含在 Logback Classic 中。它似乎适用于PatternLayout的以下转换词：

On my case I used a ThrowableConverterfor the stacktrace.
在我的情况下，我使用 aThrowableConverter作为堆栈跟踪。
You can add that to your logback.xml where you have your consoleApender, inside your encoder:
您可以将它添加到您的 logback.xml 中，在您的编码器内有您的 consoleAppender：
<appender name="consoleAppender" class="ch.qos.logback.core.ConsoleAppender">
<encoder class="net.logstash.logback.encoder.LogstashEncoder">
<!-- your other encoder configurations -->
<stackTrace>
<fieldName>stacktrace</fieldName>
<throwableConverter class="net.logstash.logback.stacktrace.ShortenedThrowableConverter">
<pattern>[%thread] - %msg%n%stack{1,1024,10,rootFirst}</pattern>
</throwableConverter>
</stackTrace>
</encoder>
</appender>
It will add a field name "stack_trace"with the stack trace. And it does the job for me.
它将在堆栈跟踪中添加一个字段名称“stack_trace”。它为我完成了这项工作。
Inside stack you have the parameters:
在堆栈内部，您有参数：
- maxDepthPerThrowable: Limits the number of stackTraceElements per throwable
- maxLength: Limits the total length in characters of the trace.
- shortenedClassNameLength: Abbreviates class names based on the
shortenedClassName - rootCauseFirst: Outputs in either 'normal' order (root-cause-last), or root-cause-first
- maxDepthPerThrowable：限制每个 throwable 的 stackTraceElements 数量
- maxLength：限制跟踪字符的总长度。
- shortedClassNameLength：基于类名的缩写
shortenedClassName - rootCauseFirst：以“正常”顺序（root-cause-last）或 root-cause-first 输出
