Spring boot：logback文件配置

resources文件夹下：新建logback-spring.xml文件。

文件内容like：

<?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{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} : %msg%n
            </pattern>
        </layout>

    </appender>

    <appender name="fileInfoLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>ERROR</level>
            <onMatch>DENY</onMatch>

        </filter>
        <encoder>

            </pattern>
        </encoder>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

        </rollingPolicy>
    </appender>

    <appender name="fileErrorLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
