Jhipster Spring 启动日志设置

Question

我使用 JHipster 创建应用程序。有什么简单的方法可以配置应用程序为每一天创建日志文件吗？我在一个文件中尝试了所有内容，但它变得越来越大而且不是很好的做法。我通过在我的服务器启动命令的末尾添加这部分来做到这一点：

>> console.log &

Logback-spring.xml :

<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <fileNamePattern>logs/log-file.%d{yyyy-MM-dd}.log</fileNamePattern>
        <maxHistory>90</maxHistory>
    </rollingPolicy>
    <encoder>
        <charset>utf-8</charset>
        <Pattern>%d %-5level [%thread] %logger{0}: %msg%n</Pattern>
    </encoder>
</appender>

<appender name="ASYNC" class="ch.qos.logback.classic.AsyncAppender">
    <queueSize>512</queueSize>
    <appender-ref ref="FILE"/>
</appender>

<!-- https://logback.qos.ch/manual/configuration.html#shutdownHook and https://jira.qos.ch/browse/LOGBACK-1090 -->
<shutdownHook class="ch.qos.logback.core.hook.DelayingShutdownHook"/>

<contextListener class="ch.qos.logback.classic.jul.LevelChangePropagator">
    <resetJUL>true</resetJUL>
</contextListener>

Answer 1

在 logback-spring.xml 中配置 RollingFileAppender 而不是使用 ConsoleAppender。参见 https://logback.qos.ch/manual/appenders.html#RollingFileAppender

JHipster 生成的 logback-spring.xml 包含了所有的产品配置，你只需要取消注释即可。

<!-- The FILE and ASYNC appenders are here as examples for a production configuration -->
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <fileNamePattern>logFile.%d{yyyy-MM-dd}.log</fileNamePattern>
        <maxHistory>90</maxHistory>
    </rollingPolicy>
    <encoder>
        <charset>utf-8</charset>
        <Pattern>%d %-5level [%thread] %logger{0}: %msg%n</Pattern>
    </encoder>
</appender>
<appender name="ASYNC" class="ch.qos.logback.classic.AsyncAppender">
    <queueSize>512</queueSize>
    <appender-ref ref="FILE"/>
</appender>
<root level="${logging.level.root}">
    <appender-ref ref="ASYNC"/>
</root>

您可以在自己的代码中使用此代码logback.xml

<appender name="dailyRollingFileAppenderError" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <File>${DEV_HOME}/error.log</File>
    <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
        <Pattern>%d [%-5level] %logger{36} - %msg%n</Pattern>
    </encoder>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <!-- daily rollover -->
        <FileNamePattern>${DEV_HOME}/error.%d{yyyy-MM-dd}.%i.log</FileNamePattern>
        <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
            <maxFileSize>10MB</maxFileSize>
        </timeBasedFileNamingAndTriggeringPolicy>
    </rollingPolicy>
</appender>


<root level="error">
    <appender-ref ref="dailyRollingFileAppenderError"/>
</root>
