security

Spring security

	  http
            .authorizeRequests()
            .antMatchers("/products").hasRole("user")
            //.antMatchers("/products/*").hasRole("admin")
            .anyRequest().permitAll();
      
      http.csrf().disable();

• use HttpSecurity to set our authorization strategy
• we can use role annotations instead
