qxo created LOG4J2-2722:
---------------------------
Summary: log4j2 config variableResolver Prefix and Suffix should
configable
Key: LOG4J2-2722
URL: https://issues.apache.org/jira/browse/LOG4J2-2722
Project: Log4j 2
Issue Type: Improvement
Components: Configurators
Affects Versions: 2.12.1
Reporter: qxo
current variableResolverPrefix=${ and variableResolverSuffix=}
There will be a issue if the variable default value has "}"
ie :
```
${env:logStdoutPattern:-%d{yyyyMMddHH:mm:ss} %-5p %c{20}:%L - %m%n}
```
if we change the variableResolverPrefix, that will solve the problem
```log4j2.proprties
variableResolverPrefix=$(
variableResolverSuffix=)
appender.console.layout.pattern=$(env:logStdoutPattern:-%d{yyyyMMddHH:mm:ss}
%-5p %c{20}:%L - %m%n)
```
