我尝试配置我的springboot应用程序一天登录一个文件,所以我配置我的logback.xml就像这样:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml"/>

    <appender name="ROLLIN" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOG_FILE}</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

            <!-- daily rollover -->
            <fileNamePattern>${LOG_FILE}.%d{yyyy-MM-dd}.log</fileNamePattern>

        </rollingPolicy>
    </appender>

    <root level="INFO">
        <appender-ref ref="ROLLIN" />
    </root>

    <logger name="org.springframework.web" level="INFO"/>
</configuration>

因此,当我尝试运行我的应用程序时,我收到此错误:

Exception in thread "main" java.lang.IllegalStateException: Logback configuration error detected: 
ERROR in ch.qos.logback.core.rolling.RollingFileAppender[ROLLIN] - No encoder set for the appender named "ROLLIN".
