Log4j2 or logback configuration template enables flexible output of service names
Introduction When we use log4j2 or logback to print logs, the service name must be added to the output content. Take log4j2 as an example: <!–Output console configuration–> <Console name=”Console” target=”SYSTEM_OUT”> <!– Format of output log –> <PatternLayout pattern=”server-case %d{yyyy-MM-dd HH:mm:ss} %5p %c{1}:%L – %m%n”/> </Console> The service name is server-case, and the output content […]

logback.xml configuration template (contains all configurations and comments, copy and paste directly and modify slightly as needed)
1. Overview Logback is a log management tool that can configure the storage path and log format of logs, classify logs and store them in specified files, set the size and storage period of log files (old logs will be deleted if they exceed the limit), and store logs on schedule or according to the […]
Java transparently transmits parameters to logback and customizes the log file name. Expired log files are automatically deleted
