Spring boot：部署为war时如何读取驻留在Tomcat中的外部文件

Question

I am deploying a Spring boot application as a war to my existing Tomcat server. I will write to a json file which resides in /conf/my.json in the root of my Tomcat server.

My Spring boot will be deployed in webapp in the root of my Tomcat server so, say my Spring boot app called mySpring , it will be at location /webapp/mySpring .

How can I read the my.json in my Spring boot app?

Thanks

Answer 1

you can use ResourceUtils to get the file. File file= ResourceUtils.getFile( "classpath:conf/my.json");
