In old spring (before spring boot) I defined in web.xml

```
<filter-mapping> 
    <filter-name>myFilter</filter-name> 
    <url-pattern>/rest/*</url-pattern> 
</filter-mapping>

```

And in this way security was applied only to URIs under "/rest/" and static resources served from root were unprotected (my html/Angular2 content) . However I cannot find any reference of doing the same in Spring Boot, has anyone already resolved this?
