Spring boot 1.5.2.RELEASE：滚动文件日志记录答案

【问题标题】：Spring boot 1.5.2.RELEASE : Rolling File loggingSpring boot 1.5.2.RELEASE：滚动文件日志记录
【发布时间】：2017-11-09 14:06:41
【问题描述】：

我在application.yml 中有以下配置

logging:
  path: logs/
  file: logs/service.log
  pattern:
      console: "%d %-5level %logger : %msg%n"
      file: "%d %-5level [%thread] %logger : %msg%n"
  level:
      com.demo.api: INFO

下面是我的logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml" />
    <include resource="org/springframework/boot/logging/logback/console-appender.xml" />
    <root level="INFO">
        <appender-ref ref="CONSOLE" />
    </root>
    <logger name="com.demo" additivity="false" level="DEBUG">
        <appender-ref ref="CONSOLE"/>
    </logger>
</configuration>

当我运行 Spring Boot 应用程序时，它没有记录到文件中，但我在控制台中看到以下登录信息，如下所示

2017-06-07 16:14:45.841  INFO 37084 --- [nio-8443-exec-8] c.d.api.Controller        : test msg 1
2017-06-07 16:14:45.854  INFO 37084 --- [nio-8443-exec-8] c.d.api.dao.Dao  : test msg 2
2017-06-07 16:14:49.188  INFO 37084 --- [nio-8443-exec-8] c.d.api.service.DigSigService   : test msg 3
2017-06-07 16:14:49.199  INFO 37084 --- [nio-8443-exec-8] c.d.api.service.DigSigService   : test msg 4
2017-06-07 16:14:49.200  INFO 37084 --- [nio-8443-exec-8] c.d.api.dao.Dao  : test msg 5

我尝试如下更新logback.xml，但仍然没有锁定记录到文件

<?xml version="1.0" encoding="UTF-8"?>
<configuration>

<property name="DEV_HOME" value="c:/logs" />

</appender>

    </encoder>

</appender>

        </timeBasedFileNamingAndTriggeringPolicy>
    </rollingPolicy>

</appender>

<!-- Send logs to both console and file audit -->
<logger name="com.demo.api" level="debug"
    additivity="false">
    <appender-ref ref="FILE-AUDIT" />
    <appender-ref ref="STDOUT" />
</logger>

<root level="error">
    <appender-ref ref="FILE-ERROR" />
</root>

</configuration>

有人可以帮我修复日志到滚动文件吗？

【问题讨论】：

您需要输入logging.path 的绝对路径，例如：C:/User/Projects/YourProject/logs。其次确保logback.xml 文件在你的类路径中：If you put a logback.xml in the root of your classpath it will be picked up from there (or logback-spring.xml to take advantage of the templating features provided by Boot)

标签： java spring logging spring-boot

【解决方案1】：

您的logback.xml 直接在资源文件夹中的什么位置？如果是这样，这应该可以立即工作（刚刚测试了您的配置，它可以工作）。如果没有，您必须指定它的位置。例如。如果它在...resources/config下，则必须在application.yml中添加以下条目：

logging:
  config: classpath:config/logback.xml
