Spring Boot Filter Implementation

Spring Boot Filter Implementation

1. Direct configuration of annotation mode

@Component @servletcomponentscan@webfilter (urlpatterns = "/*", FilterName = "Loginfilter") public class Loginfilter Implements filter{}

1, @Component The purpose of this annotation is to give loginfilter to the container to handle. Which means that loginfilter works.

2, @ServletComponentScan This use to scan @webfilter let @webfilter function. Of course, the servlet line tube annotations are also possible.

This @servletcomponentscan is best written on apllication, a generic configuration.

I do not write it on application because there is only one filter.

3, @WebFilter This use is obvious, for what link to do filter, filter name is why.

Direct Inheritance Filter

public class Loginfilter implements filter{}

or Inherit Genericfilterbean

public class Loginfilter extends genericfilterbean{}

@SpringBootApplication public class Springrestapplication {public static void main (string[] args) {springapplication.  Run (Springrestapplication.class, args); } @Bean Public Filterregistrationbean Filterregistrationbean () {Filterregistrationbean Registrationbean = new FilterR  Egistrationbean ();  Httpbasicauthorizeattribute httpbasicfilter = new Httpbasicauthorizeattribute ();  Registrationbean.setfilter (Httpbasicfilter);  list<string> urlpatterns = new arraylist<string> ();  Urlpatterns.add ("/user/*");  Registrationbean.seturlpatterns (Urlpatterns);  return Registrationbean; }  }
