当我停止运行spring-boot应用程序时，将生成 两个 日志文件，而不是 一个 （期望一个）。

我Logback-test.xml下面的文件有什么问题可能是造成此问题的原因？

logback-test.xml：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <timestamp key="myTimestamp" datePattern="yyyy-MM-dd'_'HH-mm-ss.SSS"/>

    <include resource="org/springframework/boot/logging/logback/base.xml"/>

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

    <!-- Send debug messages to System.out -->
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <!-- By default, encoders are assigned the type ch.qos.logback.classic.encoder.PatternLayoutEncoder -->
        <encoder>
            <pattern>%d{HH:mm:ss.SSS}  - %msg%n</pattern>
        </encoder>
    </appender>

    <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">

        <file>C:\path\to\my\file\myLog-${myTimestamp}.log</file>
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <Pattern>%d{yyyy-MM-dd_HH:mm:ss.SSS} - %msg%n</Pattern>
        </encoder>

        <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
            <FileNamePattern>myLog.%i{yyyy-MM-dd_HH:mm:ss.SSS}}.log</FileNamePattern>
            <MinIndex>1</MinIndex>
            <MaxIndex>10</MaxIndex>
        </rollingPolicy>

        <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
            <MaxFileSize>2MB</MaxFileSize>
        </triggeringPolicy>

    </appender>

    <logger name="com.my.package" level="INFO" additivity="false">
        <appender-ref ref="STDOUT" />
        <appender-ref ref="FILE" />
    </logger>

    <!-- By default, the level of the root level is set to DEBUG -->
    <root level="INFO">
        <appender-ref ref="STDOUT" />
    </root>

</configuration>

正在创建的两个文件例如：

myLog-2016-04-22_15-47-30.126.log

and

myLog-2016-04-22_15-47-30.922.log
