Zilong Song updated LOG4J2-1838: -------------------------------- Description: Add support for appending common suffix to each line of throwable stack trace. The suffix can be configured by patterns just like patterns used elsewhere. For example, pattern {{%xEx{suffix(- %mdc{key})}}} will append a string generated by pattern {{- }} and {{%mdc{key}}}. But throwable patterns will be automatically ignored, because they will make the rendered result confusing. So pattern {{%xEx{suffix(- %rEx%mdc{key})}}} has the same effect with {{%xEx{suffix(- %mdc{key})}}}, as if the nested {{%rEx}} pattern has never appeared. With the common suffix, the stack trace is as following: (with pattern {{suffix(- %mdc\{key\})}}, and MDC value {{test mdc suffix}} to {{key}}) {code:title=stack trace|borderStyle=solid} java.lang.IllegalArgumentException: IllegalArgument - test mdc suffix at org.apache.logging.log4j.core.pattern.ExtendedThrowablePatternConverterTest.testSuffixFromNormalPattern(ExtendedThrowablePatternConverterTest.java:48) [test-classes/:?] - test mdc suffix at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:1.8.0_91] - test mdc suffix at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[?:1.8.0_91] - test mdc suffix at java.lang.reflect.Method.invoke(Method.java:498) ~[?:1.8.0_91] - test mdc suffix at com.intellij.rt.execution.application.AppMain.main(AppMain.java:147) [idea_rt.jar:?] - test mdc suffix Caused by: java.lang.NullPointerException: null pointer - test mdc suffix at org.apache.logging.log4j.core.pattern.ExtendedThrowablePatternConverterTest.testSuffixFromNormalPattern(ExtendedThrowablePatternConverterTest.java:47) ~[test-classes/:?] - test mdc suffix ... 27 more - test mdc suffix }} {code} was: Add support for appending common suffix to each line of throwable stack trace.
