You need to set your content-type to application/json. But -d (or –data) sends the Content-Type application/x-www-form-urlencoded, which is not accepted on Spring’s side.
Looking at the curl man page, I think you can use -H (or –header):
-H “Content-Type: application/json”
Full example:
curl –header “Content-Type: application/json”
–request POST
–data ‘{“username”:”xyz”,”password”:”xyz”}’
http://localhost:3000/api/login
(-H is short for –header, -d for –data)
Note that -request POST is optional if you use -d, as the -d flag implies a POST request.
On Windows, things are slightly different. See the comment thread.
Try to put your data in a file, say body.json and then use
curl -H “Content-Type: application/json” –data @body.json http://localhost:8080/ui/webapp/conf
