TIL :: Log Exceptions on a single line with Spring Boot
This can go in the application.properties file.
# Single line. Full stack trace will be captured in a single line
logging.exception-conversion-word=%replace(%wEx){'\n','\u2028'}%nopex
# Truncated Single line. Only the exception message will be captured in a single line
logging.exception-conversion-word=%replace(%wEx{short}){'\n','\u2028'}%nopex
# Truncated. Default formatting but only capturing a single line
logging.exception-conversion-word=%wEx{short}
This works if you don’t override logging.pattern.console as the default logging.pattern.console allows you to use logging.exception-converstion-word
If you need to only filter out certain packages from exception stack trace.
logging.pattern.console="[%d{yyyy-MM-dd HH:mm:ss.SSS}] [%5level] [${spring.zipkin.service.name:${spring.application.name:-}},%X{X-B3-TraceId:-},%X{X-B3-SpanId:-}] [%15.15t] [%-40.40logger{39}] - %m%n%rEx{full,
java.lang.reflect.Method,
org.apache.catalina,
org.springframework.aop,
org.springframework.security,
org.springframework.transaction,
org.springframework.web,
org.springframework.cglib,

com.netflix.hystrix,
rx.internal,
rx.Observable,

}"
Or this ☝ can be applied with logging.exception-conversion-word
If you are using logback.xml then here is an example config. The key part is in configuration > appender > encoder > pattern
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
