java - 启动应用程序时出现 FileNotFoundException (Logback)

Question

在 tomcat 8.5.0 上运行 SpringBoot 2.0.3 应用程序时出现以下错误:

ERROR in ch.qos.logback.core.rolling.RollingFileAppender[FILE] - openFile(C:\Program Files\Apache Software Foundation\Tomcat 9.0\temp/spring.log,true) call failed. java.io.FileNotFoundException: C:\Program Files\Apache Software Foundation\Tomcat 9.0\temp\spring.log (Access is denied)

该模块的

logback-spring.xml如下:

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

    <springProperty scope="context" name="springAppName" source="spring.application.name"/>
    <include resource="org/springframework/boot/logging/logback/base.xml"/>

但当以 admin 身份运行 InteliJ 时，问题就消失了。

您可能遇到这种情况的两个原因:

1. 看看你是否有权限读取 spring.log 文件这是java.io.FileNotFoundException 最明显的原因:(访问是denied) 异常，我没有足够的权限，所以我立即提供对日志的读、写和执行权限文件并重试。

2. 查看是否有其他进程正在使用该文件这可能是另一个进程java.io.FileNotFoundException 的可能原因:(访问是拒绝)。
