@Grapes([
	@GrabConfig(systemClassLoader=true),
    @Grab(group='ch.qos.logback', module='logback-classic', version='1.2.3')
])

注意：

1、如果是使用 logback.groovy 作为配置文件，需要设置 systemClassLoader=true，否则执行脚本时会报异常：GroovyCastException: Cannot cast object

2、可以使用如下参数指定配置文件：-DLogback.configurationFile=/path/to/logback.groovy

import groovy.util.logging.Slf4j
@Slf4j
class StandardGreeting {
    def greet() {
        log.trace "Hello world"
        log.debug "Hello world"
        log.warn  "Hello world"
        log.info  "Hello world"
        log.error "Hello world"
    }
}

@Slf4j
class IceGreeting {
    def greet(msg) {
        log.trace "Hello ${msg}"
        log.debug "Hello ${msg}"
        log.warn  "Hello ${msg}"
        log.info  "Hello ${msg}"
        log.error "Hello ${msg}"
    }
}

(1..100).each{
	new StandardGreeting().greet()
	new IceGreeting().greet("ice")
}
