问题描述

SpringBoot集成日志logback.groovy报错： Groovy classes are not available on the class path. ABORTING INITIALIZATION.

logback.groovy配置文件内容如下：

//https://logback.qos.ch/translator/asGroovy.html
import ch.qos.logback.classic.encoder.PatternLayoutEncoder
import ch.qos.logback.classic.filter.ThresholdFilter
import ch.qos.logback.core.ConsoleAppender
import ch.qos.logback.core.rolling.RollingFileAppender
import ch.qos.logback.core.rolling.TimeBasedRollingPolicy

import java.nio.charset.Charset

import static ch.qos.logback.classic.Level.*
def USER_HOME = System.getProperty("user.home")
def APP_NAME = "lightsword"

scan("60 seconds")

context.name = "${APP_NAME}"
jmxConfigurator()

logger("org.springframework.web", INFO)
logger("com.springboot.in.action", TRACE)
logger("org.apache.velocity.runtime.log", INFO)

appender("CONSOLE", ConsoleAppender) {
    encoder(PatternLayoutEncoder) {
        pattern = "%d{HH:mm:ss.SSS} [%thread] %-5level %logger{35} - %msg %n"
        charset = Charset.forName("utf8")
    }
}


appender("dailyRollingFileAppender", RollingFileAppender) {
    file = "${USER_HOME}/logs/${APP_NAME}"
    rollingPolicy(TimeBasedRollingPolicy) {
        fileNamePattern = "${APP_NAME}.%d{yyyy-MM-dd}.log"
        maxHistory = 30
    }
    filter(ThresholdFilter) {
        level = ERROR
    }
    encoder(PatternLayoutEncoder) {
        pattern = "%d{HH:mm:ss.SSS} [%thread] %-5level %logger{35} - %msg %n"
    }
}
root(DEBUG, ["CONSOLE", "dailyRollingFileAppender"])

详细日志如下：

原因分析

在类路径中没有Groovy类。

解决方案

项目中添加groovy依赖：

 <!-- https://mvnrepository.com/artifact/org.codehaus.groovy/groovy-all -->
        <dependency>
            <groupId>org.codehaus.groovy</groupId>
            <artifactId>groovy-all</artifactId>
            <version>${groovy.version}</version>
        </dependency>
