java - Using custom method security annotation in spring security -


i want tag methods in class custom annotation control authorization decisions using spring security. example:

@role("admin") public void accesscontrolledmethod(){}

i understand means somehow need register custom annotation "role" can result in configattributes being present when authorization decision made accessdecisionmanager. however, not understand how register custom annotation spring security recognized.

i see 1 potential solution in framework code. there class called securedannotationsecuritymetadatasource documentation says "inject annotationmetadataextractor custom annotations". if preferred method, i'm not sure how configure securedannotationsecuritymetadatasource or how inject annotationmetadataextractor it.

you can extend globalmethodsecurityconfiguration in configuration : 

@enableglobalmethodsecurity @configuration public class mymethodsecurityconfig extends globalmethodsecurityconfiguration {      protected methodsecuritymetadatasource custommethodsecuritymetadatasource() {         return securedannotationsecuritymetadatasource(...);     }     }

in xml, can : 

<global-method-security metadata-source-ref="custommethodsecuritymetadatasource"> ... </global-method-security> <bean id="custommethodsecuritymetadatasource"  class="org.springframework.security.access.annotation.securedannotationsecuritymetadatasource"> ... </bean>

custommethodsecuritymetadatasource can instanceof methodsecuritymetadatasource

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
