尝试在现有 gradle 项目上启动 springboot 应用程序时出错

Question

我已经从 Git 克隆了项目，但是当我运行应用程序 class 时出现此错误。

Logging system failed to initialize using configuration from 'classpath:logback-spring.xml'

Answer 1

从日志看来，用户（通过它登录，例如 abhishek）没有创建目录 /opt/apps/aggregator/api/logs 的权限

所以首先要确保运行 Springboot 服务器的用户（abhishek）有创建目录的权限。

您可以通过在（/opt/、/opt/apps/ 和子目录中执行 ls -ltra 来检查它们是否已经存在）

例如

-rw-r--r-- 1 raviy raviy 655 2019 年 2 月 25 日.profile -rw-r--r-- 1 raviy raviy 220 2019 年 2 月 25 日.bash_logout

这里 raviy 是所有者，如果您不是所有者，则更改权限（使用 sudo 或询问管理员）

chmod -R 777 /opt （ 777 应该避免，它运行你的程序）

之后 java 应该能够创建目录
