logback.xml中的file和stdout appenders

Question

我logback.xml在单独的项目中有2个文件.一个使用FileAppender将JDBC SQL记录到文件中,另一个使用ConsoleAppender将错误记录到stdout.

这是我的每个logback.xml文件.

文件记录

<configuration>
    <appender name="FILE" class="ch.qos.logback.core.FileAppender">
        <file>${user.home}/database.log</file>
        <append>false</append>
        <encoder>
            <pattern>%-5relative %-5level %logger{35} - %msg%n</pattern>
        </encoder>
    </appender>

    <logger name="jdbc" level="OFF" />
    <logger name="jdbc.sqlonly" level="debug" />

    <root level="info">
        <appender-ref ref="FILE" />
    </root>
</configuration>

控制台记录

<configuration>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%-5relative %-5level %logger{35} - %msg%n</pattern>
        </encoder>
    </appender>

    <logger name="jdbc" level="OFF" />

    <root level="ERROR">
        <appender-ref ref="STDOUT" />
    </root>
</configuration>

我正在合并这两个项目,我希望能够继续将信息级SQL记录到文件中,并将错误记录到STDOUT.

我已经添加了两个appender logback.xml但我不知道如何处理记录器和新的root标签logback.xml.

试试这个:

    <configuration>
        <appender name="FILE" class="ch.qos.logback.core.FileAppender">
            <file>${user.home}/database.log</file>
            <append>false</append>
            <encoder>
                <pattern>%-5relative %-5level %logger{35} - %msg%n</pattern>
            </encoder>
        </appender>

        <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
            <encoder>
                <pattern>%-5relative %-5level %logger{35} - %msg%n</pattern>
            </encoder>
        </appender>


        <logger name="jdbc" level="OFF" />
        <logger name="jdbc.sqlonly" level="INFO" additivity="false">
            <appender-ref ref="FILE" />
        </logger>

        <root level="ERROR">
            <appender-ref ref="STDOUT" />
        </root>
    </configuration>

如果你想在文件和控制台中查看输出,请使用两个appender-ref,如下所示:

 <configuration>
    <appender name="FILE" class="ch.qos.logback.core.FileAppender">
        <file>${user.home}/database.log</file>
        <append>false</append>
        <encoder>
            <pattern>%-5relative %-5level %logger{35} - %msg%n</pattern>
        </encoder>
    </appender>

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%-5relative %-5level %logger{35} - %msg%n</pattern>
        </encoder>
    </appender>


    <logger name="jdbc" level="OFF" />
    <logger name="jdbc.sqlonly" level="INFO" additivity="false">
        <appender-ref ref="FILE" />
    </logger>

    <root level="ERROR">
        <appender-ref ref="STDOUT" /> <!-- Every log will apear on screen log -->
        <appender-ref ref="FILE" />   <!-- Every log will apear on file -->
    </root>
</configuration>
