Question

我正在尝试使用springboot logback日志记录框架来记录我的信息。不幸的是，当我记录信息警告错误时，时间戳记与应用程序服务器启动时间完全相同。

My logback.xml configuration information is as follows:


<?xml version="1.0" encoding="UTF-8"?>
<configuration
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="http://www.padual.com/java/logback.xsd"
        debug="false" scan="true" scanPeriod="30 second">
    <property name="PROJECT" value="AmazonRss" />
    <property name="ROOT" value="logs/${PROJECT}/" />
    <property name="FILESIZE" value="10MB" />
    <property name="MAXHISTORY" value="100" />
    <timestamp key="DATETIME" datePattern="yyyy/MM/dd HH:mm:ss" />
    <!-- Console printing -->
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder charset="utf-8">
            <pattern>[%-5level] %d{${DATETIME}} [%thread] %logger{36} - %m%n
            </pattern>
        </encoder>
    </appender>

........

我的日志如下：

很明显，我在服务器启动很多时间后才运行我的服务，但是运行时日志信息与服务启动时的时间戳相同。

我是登录的新手，我不知道此问题是如何产生的。如果您能提供一些建议，我将不胜感激。

<timestamp标记不用于包含属性。在开始时对其进行评估，并将其值替换为结果。这意味着您最终得到的等同于：

<pattern>[%-5level] %d{2019-04-17 16:48:44} [%thread] %logger{36} - %m%n

因此是固定的日期时间。 The documentation对此进行了澄清：

timestamp元素具有两个强制属性key和 datePattern和可选的timeReference属性。 key属性是密钥的名称，在该密钥下时间戳可用于后续配置元素作为变量。 datePattern 属性表示用于转换当前时间的日期模式（在其中解析配置文件）成字符串。日期模式应遵循SimpleDateFormat中定义的约定。的 timeReference属性表示时间戳的时间参考。 默认值为配置的解释/解析时间文件，即当前时间。但是，在某些情况下使用上下文出生时间作为时间参考可能会很有用。这个可以通过将timeReference属性设置为 "contextBirth"。

改为使用常规属性：

<property name="MAXHISTORY" value="100" />
<property name="DATETIME" value="yyyy/MM/dd HH:mm:ss" />
<!-- Console printing -->
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder charset="utf-8">
        <pattern>[%-5level] %d{${DATETIME}} [%thread] %logger{36} - %m%n
        </pattern>
    </encoder>
</appender>
