My database is setup correctly. The POSTGRES JDBC drivers are also in path (I was able to create another DAO, connect to the database and query the authtable described above).

When I type in localhost:8080/login, the login screen is displayed correctly. However, after filling in credentials, if I hit the submit button, I get the following error:

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.
Mon Jun 22 12:02:03 IST 2015
There was an unexpected error (type=Method Not Allowed, status=405).
Request method 'POST' not supported

On the server console, I get the following log:

2015-06-22 12:04:01.846  WARN 9178 --- [nio-8080-exec-2] o.s.web.servlet.PageNotFound             : Request method 'POST' not supported

What am I doing wrong?


Answer:

There are 2 things flawed in your setup.

  1. You should post to /login instead of /j_spring_security_check as that is the new URL when using java config (and in Spring 4 for XML config also).
  2. You have set the usernameParameter to name and your form still has username.

Fix those flaws in your login page.
