Filters not working in Struts2

Question

for some unknown reason I'm not being able to use filter on struts2. I'm using apache tomcat and using filter to restrict user access ( I preffer rather than Interceptors). Is there any reason why my requests with /tela-paciente is not being filtering??

   <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <filter>
        <filter-name>Paciente</filter-name>
        <filter-class>br.ufg.inf.sas.filtros.FiltroPaciente</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>Paciente</filter-name>
        <url-pattern>/tela-paciente</url-pattern>
    </filter-mapping>

Answer 1

Another thing to keep in mind is that in your example the mapping for /tela-paciente occurs after the mapping for /* (for the Struts2 filter), so all requests will be mapped to Struts2 and none will go to your security filter.

Remember that the order of your filters matters. :)

@totaam: The StrutsPrepareAndExecuteFilter does not chain on to other filters unless:

• The request URL is excluded from processing by the struts.action.excludePattern property
• The request does not map to an action or a static resource

Therefore, assuming his request does map to an action, his security filter will not be invoked if it is mapped after the Struts2 filter.
