In eclipse if I start spring boot application, then application serving images for this url
http://localhost:8080///////images//profile//APM1184//originalImage_7a7zke527_.jpeg
If I deploy war file of this project in local tomcat 8 and start. This URL is not working saying 404 not found.
I have posted my code. please correct me where I went wrong.

Answer 1

Having hard coded resource locations and mongo hosts is going to make it hard for you to manage your application. I would recommend moving those values into a configuration file. At the same time I would recommend using relative or root directory locations for resources instead of having the C:\ in the path as that won't work for deployments to Linux or other environments where the resource isn't on the C:\. My guess is that Tomcat isn't allowing the application to read from that external location due to some security constraints on the Tomcat installation.
I would recommend reading this Getting Started Guide on serving static content: https://spring.io/blog/2013/12/19/serving-static-web-content-with-spring-boot
