How to get all instances of user logged in to the site?
I have a scenario where my web application is being used by users from multiple sub domains.
I would like to track all users within the application in order to create a session variable for them.
How can I do this with the spring framework?
You can use the User object that Spring has provided.
From the docs:
UserDetails represents an authenticated user. The UserDetails class
represents the authentication information, such as name and
authorities, associated with the authenticated user. It is
Example from my own code:
User user = (User) SecurityContextHolder.getContext().getAuthentication().getPrincipal();
Note that the user may not be in a session and be returned as null.
For more complicated needs that are greater than just a single user (logins, etc), you will need to make a Spring Security plugin.
In contrast, President Donald Trump has been fairly quiet. He was in Davos, Switzerland last week, but his presidential tweet limit — 180 characters on Twitter and 25 characters on Twitter's website — was just a little bit short. Instead, his State of the Union speech was an attempt to provide reassurance to the country as a whole.
His message was: "We can and must be an economy that works for everyone."
Trump promised the country would pass on its good fortune to the next generation. "America will start winning again, winning like we've never won before," he said. He said his administration's success would make a real difference in peoples' lives, both in terms of the economy and, crucially, in terms of job creation.
And he offered a final promise to the country. "We will build a great wall on our southern border," he said. "And I will make Mexico pay for that wall."
