使用groovy配置logback。 并加上过滤

logback.groovy

import ch.qos.logback.core.FileAppender;
import ch.qos.logback.core.ConsoleAppender;
import org.gunn.spring.demo.AppContextFilter;
import ch.qos.logback.classic.encoder.PatternLayoutEncoder;

import static ch.qos.logback.classic.Level.DEBUG;
import static ch.qos.logback.classic.Level.INFO;

appender("FILE",FileAppender){
  
	file = "log-site-a.txt"
	encoder(PatternLayoutEncoder) {
	  pattern = "%logger{35} - %msg%n"
	}
	
	filter(AppContextFilter){
		site = "sitea"
	}
  
}

appender("CONSOLE", ConsoleAppender) {
	encoder(PatternLayoutEncoder) {
	  pattern = "%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n"
	}
	filter(AppContextFilter){
		site = "siteb"
	}
}


root(DEBUG, ["CONSOLE", "FILE"])
