            .antMatchers("/admin/**").hasRole("ADMIN")                                      
            .antMatchers("/db/**").access("hasRole('ADMIN') and hasRole('DBA')")            
            .anyRequest().authenticated()                                                   
            .and()

protected void configure(HttpSecurity http) throws Exception {
