I have a REST API based on Spring boot 1.3.3. I use Velocity only for email template.
There is no JSP/HTML view. I use exclusively RestController from Spring.
Sometimes, I get this error: "ResourceManager : unable to find resource 'error.vm' in any resource loader."
It's exclusively this vm file which is requested.
Should I disable something to my Spring Boot app to disable this error?
I believe Velocity is looking for this template if it has an errors so you may have a problem with a template and it trying to get the error content but cannot. Per http://s2velocity.sandbox.seasar.org/en/error_template.html "when an error caught in a view template and rendering is forwarded to error.vm."
You can change the name of this in the property files according to the documentation.
I don't think you want to suppress these messages so you should try to catch the errors and see what the problem is.
