sprigboot项目中配置xml格式的logback

slf4j依赖和logback的依赖

idea中springboot项目的resources目录下新建logback-spring.xml文件，内容大致如下：

<?xml version="1.0" encoding="UTF-8" ?>

<configuration>

    <appender name="consoleLog" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <pattern>
                %d - %msg%n
            </pattern>
        </layout>
    </appender>

    <appender name="fileInfoLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <!--除了WARN级别的日志不输出外，其他级别日志都输出-->
            <level>WARN</level>
            <onMatch>DENY</onMatch>
            <onMismatch>ACCEPT</onMismatch>
        </filter>
        <encoder>
            <pattern>
                %msg%n
            </pattern>
        </encoder>
        <!--滚动策略-->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--路径-->
            <fileNamePattern>/Users/yanguobin/Desktop/shell/info.%d.log</fileNamePattern>
        </rollingPolicy>
    </appender>

    <appender name="fileWarnLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <!--只输出WARN及以上级别的日志-->
            <level>WARN</level>
        </filter>
        <encoder>
            <pattern>
                %msg%n
            </pattern>
        </encoder>
        <!--滚动策略-->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--路径-->
            <fileNamePattern>/Users/yanguobin/Desktop/shell/warn.%d.log</fileNamePattern>
        </rollingPolicy>
    </appender>

    <root level="info">
        <appender-ref ref="consoleLog" />
        <appender-ref ref="fileInfoLog" />
        <appender-ref ref="fileWarnLog" />
    </root>

</configuration>

测试类如下：

package com.example.shell;

import lombok.extern.slf4j.Slf4j;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
@Slf4j
public class LoggerTest 

    @Test
    public void test1()
        log.debug("debug...");
        log.info("info...");
        log.warn("warn...");
        log.error("error...");
    

 桌面生成了日志文件
