带有嵌入式 tomcat 的 Spring Boot 在临时文件夹中创建空目录

Question

我创建了在 CentOS 机器上运行的 Spring Boot 应用程序。 当应用程序运行时，临时文件夹中创建了一些空目录，如下所示 - tomcat.xxxxxxxxxxxxxxx.8080

[root@CentOS-QA-125 backend-service]# cd /tmp/
[root@CentOS-QA-125 tmp]# ls
hsperfdata_nobody                                                        tomcat.4470692394951712929.8080  tomcat.7632125794043236543.8080

有没有办法限制或避免创建这些文件夹？ 有什么方法可以将这些文件夹重定向到其他位置？

Answer 1

您可以使用server.tomcat.basedir 控制目录的位置。正如您所观察到的，它默认为一个临时目录，但您可以根据需要配置不同的位置。

Answer 2

使用选项 -Djava.io.tmpdir= 在服务器启动参数中始终有效
