java - Spring Authentication object is null -

i'm trying access authentication object in order user's name, authentication object null.

    authentication authentication = securitycontextholder.getcontext().getauthentication();     if (authentication == null) {         log.warn("authentication null during current user name!");         return anonymous_user;     }     return authentication.getname(); 

however can call (from same method):

httpservletrequest req = (httpservletrequest)inrequest; string user = req.getremoteuser(); 

and discover user set correctly.

edit: found stated problem may due not having gone through security filter chain.

so added in filter chain, no success.

here web.xml:

<filter>   <filter-name>springsecurityfilterchainproxy</filter-name>   <filter-class>org.springframework.web.filter.delegatingfilterproxy</filter-class> </filter>  <filter-mapping>   <filter-name>springsecurityfilterchainproxy</filter-name>   <url-pattern>/*</url-pattern> </filter-mapping>    <filter>     <filter-name>cors</filter-name>     <filter-class>com.us.tsp.rest.corsfilter</filter-class>   </filter>   <filter-mapping>     <filter-name>cors</filter-name>     <url-pattern>/jaxrs/*</url-pattern>   </filter-mapping> 

here spring config xml:

    <bean id="securitycontextpersistencefilter"          class="org.springframework.security.web.context.securitycontextpersistencefilter"/>  <bean id="springsecurityfilterchainproxy" class="org.springframework.security.web.filterchainproxy">   <sec:filter-chain-map >      <sec:filter-chain pattern="/**" filters="            securitycontextpersistencefilter" />   </sec:filter-chain-map> </bean> 

end edit
