logBack TimeBaseadRollingPolicy不会使用日志文件的所需名称保存日志

Question

我想在我的Spring Boot项目中配置TimeBaseedRollingPolicy。我希望将日志文件保存在模式的“ mylog。％d {yyyy-mm-dd} .log”中。

我的logBack-spring.xml文件看起来如下：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <appender name="Console"
        class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %5p{${LOG_LEVEL_PATTERN}} %15.15t - %-80.80c{1.} %X{username} %X{ipaddress} : %msg%n</pattern>
        </encoder>
    </appender>

    <appender name="RollingFile"
        class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${catalina.base}/logs/mylog.log</file>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %5p{${LOG_LEVEL_PATTERN}} %15.15t - %-80.80c{1.} %X{username} %X{ipaddress} : %msg%n</pattern>
        </encoder>
        <rollingPolicy
            class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${catalina.base}/logs/mylog.%d{yyyy-MM-dd}.log</fileNamePattern>
        </rollingPolicy>
    </appender>

    <root level="INFO">
        <appender-ref ref="Console" />
        <appender-ref ref="RollingFile" />
    </root>
</configuration>

但是它不起作用，创建日志文件，但不是标题为mylog，而是默认的“ localhost_access_log.2022-05-16”。有人可以帮我吗？

声明TIMESTAMP单独参考fileNamePattern

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
   <timestamp key="timestamp" datePattern="yyyy-MM-dd"/>
    // place all your appenders
    <appender name="RollingFile"
        .
        .
        .
        <rollingPolicy
            class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${catalina.base}/logs/mylog.${timestamp}.log</fileNamePattern>
        </rollingPolicy>
    </appender>
</configuration>
