java - 在 Linux 上部署 spring boot 应用程序时，日志文件端点出现错误 404

Question

我有一个为 REST API 编写的简单 spring boot 应用程序。我正在尝试使用 logback 将日志记录到文件中。当应用程序部署在我的 Windows 机器上的 eclipse 中时，它工作正常，我可以在/logfile 端点上看到我的所有日​​志。

当我在 Linux 机器上部署相同的应用程序时，日志文件按预期创建和更新，但是当我尝试通过浏览器访问日志文件时，我在同一端点(/日志文件)上收到 404。

任何帮助将不胜感激

我的logback配置如下

logback-spring.xml

    <?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml"/>
    <logger name="org.springframework.web" level="DEBUG" additivity="false">
        <appender-ref ref="CONSOLE"/>
        <appender-ref ref="FILE"/>
    </logger>
    <logger name="api.controllers" level="DEBUG" additivity="false">
        <appender-ref ref="CONSOLE"/>
        <appender-ref ref="FILE"/>
    </logger>
 </configuration>

我的 application.properties 文件看起来像

    server.contextPath=/api
#Configure Access Logs
server.tomcat.basedir=log
server.tomcat.accesslog.enabled=true
server.tomcat.accesslog.pattern=%t %a "%r" %s (%D ms)

#configure other log
logging.file=log/vixenapi.log 
logging.level.org.springframework.web=DEBUG
logging.level.org.springframework.boot.autoconfigure.logging=DEBUG
logging.level.org.hibernate=ERROR
#-------------------------------------

spring.jackson.serialization-inclusion=non_empty

#By Default include all properties. If a view property hasn't been set then it will be shown 
spring.jackson.mapper.DEFAULT_VIEW_INCLUSION=true

日志文件将异常记录为

在您的最小示例和问题配置中， logging.file 属性的值中都有一个尾随空格。问题中的值是 "log/vixenapi.log "，它应该是 "log/vixenapi.log"。

您可以通过为 org.springframework.boot.actuate.endpoint.mvc 启用调试日志记录来确认问题。 LogFileMvcEndpoint 将在日志文件不存在时记录一条消息，其中包含已检查的路径:

2017-11-17 14:40:24.801 DEBUG 30140 --- [nio-8080-exec-1] o.s.b.a.endpoint.mvc.LogFileMvcEndpoint  : Log file 'file [/Users/awilkinson/Downloads/test_api/log/test.log ]' does not exist

注意路径末尾的尾随空格。
