多分あなたはこれで終わったかもしれませんが、私は動的な「宛先」アドレスを設定する方法を見つける必要がありました.私のソリューションを共有しています。
小さな実行レポートを送信するために使用SMTPAppender
していますが、それらは別のメールボックスに送信する必要があります。ソリューションは問題ないように見えますが、少なくとも結果には非常に満足しています。
私のlogback.xml:
<!-- this is the trick: a converter to use on the "to" field pattern -->
<conversionRule conversionWord="smtpTo" converterClass="com.example.logback.MyConverter" />
<appender name="SMTP" class="ch.qos.logback.classic.net.SMTPAppender">
<!-- a filter to select just the log entries that will be sent by mail -->
<filter class="com.example.logback.MyFilter" />
<!-- an evaluator, mine is like CounterBasedEvaluator from the manual:
http://logback.qos.ch/xref/chapters/appenders/mail/CounterBasedEvaluator.html
-->
<evaluator class="com.example.logback.MyEvaluator">
<limit>25</limit>
</evaluator>
<!-- a discriminator to create a cyclic buffer for each mailing group I need -->
<discriminator class="com.example.logback.MyDiscriminator" />
<!-- just matching buffer size to evaluator limit -->
<cyclicBufferTracker class="ch.qos.logback.core.spi.CyclicBufferTrackerImpl">
<bufferSize>25</bufferSize>
</cyclicBufferTracker>
<smtpHost>${smtp.host}</smtpHost>
<smtpPort>${smtp.port}</smtpPort>
<SSL>${smtp.ssl}</SSL>
<username>${smtp.username}</username>
<password>${smtp.password}</password>
<from>${smtp.from}</from>
<!-- here you use the converter: in this case will get data
from marker containing the destination addresses
-->
<to>%smtpTo</to>
<subject>my subject</subject>
<layout class="ch.qos.logback.classic.PatternLayout">
<pattern>%date: %message%n%xThrowable{full}</pattern>
</layout>
</appender>
MyFilter.java:
public FilterReply decide(ILoggingEvent event) {
return event.getMarker() != null
&& event.getMarker().contains("REPORT") ? FilterReply.ACCEPT
: FilterReply.DENY;
}
MyDiscriminator.java:
public String getDiscriminatingValue(ILoggingEvent e) {
Marker marker = e.getMarker();
if (marker == null || !(marker instanceof MyMarker)) {
return null;
}
return ((MyMarker) marker).getDiscriminatingValue();
}
MyConverter.java:
public class MyConverter extends ClassicConverter {
@Override
public String convert(ILoggingEvent event) {
Marker marker = event.getMarker();
if (marker == null || !(marker instanceof MyMarker)) {
return null;
}
return ((MyMarker) marker).getSmtpTo();
}
}
MyMarker.java:
public interface MyMarker extends Marker {
// a list of destination addresses, like "a@c.com, x@y.net"
String getSmtpTo();
// an "id" to tell the buffers apart, could be "smtpTo" itself
// but in my case it would mix different reports that goes to the same addresses
String getDiscriminatingValue();
}
の実装を作成し、MyMarker
報告する必要があるすべてのログ ステートメントでそのインスタンスをいくつか使用しました。
// suggestion: make the marker immutable, then you can store and reuse them instead of recreating them every time
Marker marker1 = new MyMarkerImpl(
"REPORT", // marker name
"me@company.com, joe@company.com", // smtpTo
"alertGroup"); // discriminatingValue
logger.warn(marker1, "SNAFU");
Marker marker2 = new MyMarkerImpl(
"REPORT", "boss@company.com, ceo@company.com", "phbGroup");
logger.info(marker2, "Everything is fine");
// here we have same smtpTo as above but different discriminatingValues, so this will be sent in another email/report
Marker marker3 = new MyMarkerImpl(
"REPORT", "me@company.com, joe@company.com", "bugFixingGroup");
logger.error(marker3, "Why things gone bad", exception);
それが役に立つことを願っています。
