Adding a logout link

In this recipe, you'll learn how to add a URL /logout to let the user log out.

How to do it…

In the SecurityConfig class, in the configure() method, call the logout() method and the logoutRequestMatcher() method to declare a logout URL:

protected void configure(HttpSecurity http) throws Exception { 
  ...
  AntPathRequestMatcher pathRequestMatcher = new AntPathRequestMatcher("/logout");
  http.logout().logoutRequestMatcher(pathRequestMatcher); 
}

Note

Use org.springframework.security.web.util. matcher .AntPathRequestMatcher, and not the deprecated org.springframework.security.web.util.AntPathRequestMatcher class.

How it works…

While going to the URL /logout, the user will be logged out.
