Browser caches user authorities when using Waffle security

When using Waffle security (with Spring security, in my case) I discovered that both Internet Explorer (9) and Firefox (5) caches authorities bounded to user. I discovered this when I’ve chagned required user group to access my application and then I added current user to required group but no change. I couldn’t gain access. After some debugging it appeared that Waffle returns unchanged set of authorities for current user.
Reloading browser, tomcat and clearing all caches and data didn’t work. I’m sure that Chrome would work neither.
Firefox has convenient way to clear active logins. Click Tools-> Clear recent history -> [check]active logins

Finally I got the solution – user should logout and login again into windows box…

New HTTP Logger Grails plugin

I've wrote a new Grails plugin - httplogger. It logs:

  • request information (url, headers, cookies, method, body),
  • grails dispatch information (controller, action, parameters),
  • response information (elapsed time and body).

It is mostly useful for logging your REST traffic. Full HTTP web pages can be huge to log and generally waste your space. I suggest to map all of your REST controllers with the same path in UrlMappings, e.g. /rest/ and configure this plugin with this path.

Here is some simple output just to give you a taste of it.

17:16:00,331 INFO  filters.LogRawRequestInfoFilter  - 17:16:00,340 INFO  filters.LogRawRequestInfoFilter  - 17:16:00,342 INFO  filters.LogGrailsUrlsInfoFilter  - 17:16:00,731 INFO  filters.LogOutputResponseFilter  - >> #1 returned 200, took 405 ms.
17:16:00,745 INFO  filters.LogOutputResponseFilter  - >> #1 responded with '{count:0}'

17:18:55,802 INFO  filters.LogOutputResponseFilter  - >> #2 responded with ''

Official plugin information can be found on Grails plugins website here: http://grails.org/plugins/httplogger or you can browse code on github: TouK/grails-httplogger.

Spring Security by example: securing methods

This is a part of a simple Spring Security tutorial:

1. Set up and form authentication
2. User in the backend (getting logged user, authentication, testing)
3. Securing web resources
4. Securing methods
5. OpenID (login via gmail)
6. OAuth2 (login via Facebook)
7. Writing on Facebook wall with Spring Social

Securing web resources is all nice and cool, but in a well designed application it's more natural to secure methods (for example on backend facade or even domain objects). While we may get away with role-based authorization in many intranet business applications, nobody will ever handle assigning roles to users in a public, free to use Internet service. We need authorization based on rules described in our domain.

For example: there is a service AlterStory, that allows cooperative writing of stories, where one user is a director (like a movie director), deciding which chapter proposed by other authors should make it to the final story.

The method for accepting chapters, looks like this:
