How to use filter in Springboot

The use of filter in the normal spring MVC framework requires configuration in the XML file

<filter>    <filter-name>xxxFilter</filter-name>    <filter-class> Xx.xx.xx.xx.xxxfilter</filter-class></filter><filter-mapping>    <filter-name> Xxxfilter</filter-name>    <url-pattern>/*</url-pattern></filter-mapping>

However, the XML configuration is discarded in spring boot, so to add a in the startup main function

@Bean
Public Filterregistrationbean Filterregistrationbean () {
   Filterregistrationbean Registrationbean = new Filterregistrationbean ();
   Wechatfilter wechatfilter = new Wechatfilter ();
   Registrationbean.setfilter (Wechatfilter);
   list<string> urlpatterns = new arraylist<string> ();
   Urlpatterns.add ("/validate/*");
   Registrationbean.seturlpatterns (Urlpatterns);
   return Registrationbean;
}
Add:

If you want to execute the Services method in filter, execute the method in the Initialize filter (because the filter is executed in advance with the services)
