我需要在记录器中打印类，方法和行号。为此，我使用以下条目：

<appender name="ErrorFileAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>${log.dir}error.log</file>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <!-- daily rollover -->
        <fileNamePattern>${log.dir}error.%d{yyyy-MM-dd}.%i.log</fileNamePattern>
        <maxHistory>3</maxHistory>
        <!--<totalSizeCap>10MB</totalSizeCap>-->
        <TimeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
            <MaxFileSize>10MB</MaxFileSize>
        </TimeBasedFileNamingAndTriggeringPolicy>
    </rollingPolicy>
    <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
        <Pattern>
            %d %-5p [%X{sessionId}] [%X{userId}] %C{1}.%-M:%L] %m%n
        </Pattern>
    </encoder>
    <!--<encoder>
        <pattern>%d %-5p [%X{sessionId}] [%X{userId}] %C{1}.%-M:%L] %m%n</pattern>
    </encoder>-->
</appender>
<root level="ERROR">
    <appender-ref ref="ErrorFileAppender" />
</root>

如您所见，我的模式是

%d %-5p [%X{sessionId}] [%X{userId}] %C{1}.%-M:%L] %m%n

然后我收到以下错误：

但如果我使用

%d %-5p [%X{sessionId}] [%X{userId}] %m%n

然后没有错误。

有人可以看看。这是我的pom条目：

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>jcl-over-slf4j</artifactId>
    <version>1.7.25</version>
</dependency>
<dependency>
    <groupId>org.logback-extensions</groupId>
    <artifactId>logback-ext-spring</artifactId>
    <version>0.1.4</version>
</dependency>
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.2.3</version>
    <scope>test</scope>
</dependency>

答案 0 :(得分：0)

将%-M更改为%M。

所以你的模式变成了：

<Pattern>
    %d %-5p [%X{sessionId}] [%X{userId}] %C{1}.%M:%L] %m%n
</Pattern>
