关于日志记录：如何在Spring Boot的application.yml中配置滚动文件附加程序

How to configure rolling file appender within Spring Boot's application.yml

是否可以在Spring Boot应用程序的application.yml中配置每日文件追加程序？

即文件名模式：myfile。％d {yyyy-MM-dd-HH-mm-ss} .log

我的application.yml文件中具有以下配置。

1
2
3
4
5
6

logging:

file: /mypath/myfile.log

level:
mypackage: INFO

谢谢

默认文件附加器基于大小(10MB)。

在您的logback.xml中，按照此处所述配置TimeBasedRollingPolicy

即就像是：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<include resource="org/springframework/boot/logging/logback/base.xml"/>

<file>${LOG_FILE}</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">


<fileNamePattern>${LOG_FILE}.%d{yyyy-MM-dd}.log</fileNamePattern>

</rollingPolicy>
</appender>

<root level="INFO">

</root>

<logger name="org.springframework.web" level="INFO"/>
</configuration>

要覆盖默认文件附加器并将其更改为每日翻转，可以使用如下所示的logback-spring.xml：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<include resource="org/springframework/boot/logging/logback/defaults.xml"/>
<property name="LOG_FILE" value="${LOG_FILE:-${LOG_PATH:-${LOG_TEMP:-${java.io.tmpdir:-/tmp}}/}spring.log}"/>
<include resource="org/springframework/boot/logging/logback/console-appender.xml"/>

<appender name="ROLLING-FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<encoder>
<pattern>${FILE_LOG_PATTERN}</pattern>
</encoder>
<file>${LOG_FILE}</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

<fileNamePattern>${LOG_FILE}.%d{yyyy-MM-dd}.log</fileNamePattern>
</rollingPolicy>
</appender>

<root level="INFO">

</root>

</configuration>

聚会晚了一点……但是我可以使用application.yaml中的以下配置(没有任何logback.xml配置)使日志文件按大小滚动(按大小)：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18

logging:
file: /var/log/webapps/app/app.log

# Roll the log file when it reaches max size
file.max-size: 1024KB

# Limit the number of log files retained
file.max-history: 50

pattern:
console:"%d %-5level %logger : %msg%n"
file:"%d %-5level [%thread] %logger : %msg%n"

level:
root: info
my.package.of.app: debug
org.springframework: error
# etc. etc.

您还可以根据自己的文件大小配置滚动策略
logback-spring.xml。在下面，我们为SizeBasedTriggeringPolicy指定最大文件大小为10MB：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
26
27
28
29
30
31

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

<configuration>

<include resource="org/springframework/boot/logging/logback/defaults.xml" />
<property name="LOG_FILE" value="${LOG_FILE:-${LOG_PATH:-${LOG_TEMP:-${java.io.tmpdir:-/tmp}}/}spring.log}"/>
<include resource="org/springframework/boot/logging/logback/console-appender.xml" />

<appender name="ACTUAL_LOG_FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<encoder>
<pattern>${FILE_LOG_PATTERN}</pattern>
</encoder>
<file>${LOG_FILE}</file>
<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">

<fileNamePattern>${LOG_FILE}.%i.gz</fileNamePattern>
<minIndex>1</minIndex>
<maxIndex>10</maxIndex>
</rollingPolicy>
<triggeringPolicy
class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<MaxFileSize>10MB</MaxFileSize>
</triggeringPolicy>
</appender>

<root level="INFO">

</root>

</configuration>
