Springbootのlogback設定

Question

私はので、私はちょうどこのように私のlogback.xmlを構成する日のために一つのファイルにログインするために私のspringbootアプリを設定するにはtryng：

<?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> 

私は私のアプリを実行しようとするので、私はこのエラーを得ました：

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".

例外として、エンコーダは定義されていません。公式documentation

を参照してください詳細については

<appender name="ROLLIN" class="ch.qos.logback.core.rolling.RollingFileAppender"> 
    <file>logFile.log</file> 
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> 
     <!-- daily rollover --> 
     <fileNamePattern>logFile.%d{yyyy-MM-dd}.log</fileNamePattern> 

     <!-- keep 30 days' worth of history capped at 3GB total size --> 
     <maxHistory>30</maxHistory> 
     <totalSizeCap>3GB</totalSizeCap> 

    </rollingPolicy> 

    <encoder> 
     <pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n</pattern> 
    </encoder> 
    </appender> 

のようなものを試してみてください
