spring - Why can't @Value inject a JNDI value from the Environment? -

-

i'm having trouble injecting jndi values tomcat spring java config using @value annotation whereas have no trouble retreiving values via environment class. using java 1.7.0_17, spring 4.0.3, , tomcat 7.0.52 .

i have in context.xml following variables defined:

<environment name="user_name" value="initech" type="java.lang.string" /> <environment name="user_password" value="1n3+3ch!" type="java.lang.string" />

in java configuration file have following code working:

@bean public foo foo( environment env ){     return new foo( env.getproperty("user_name"), env.getproperty("user_password") ); }

when server log see:

12:50:45.214 [rmi tcp connection(3)-127.0.0.1] debug o.s.c.e.propertysourcespropertyresolver -> searching key 'user_name' in [servletconfiginitparams] 12:50:45.214 [rmi tcp connection(3)-127.0.0.1] debug o.s.c.e.propertysourcespropertyresolver -> searching key 'user_name' in [servletcontextinitparams] 12:50:45.214 [rmi tcp connection(3)-127.0.0.1] debug o.s.c.e.propertysourcespropertyresolver -> searching key 'user_name' in [jndiproperties] 12:50:45.214 [rmi tcp connection(3)-127.0.0.1] debug o.springframework.jndi.jnditemplate -> looking jndi object name [java:comp/env/user_name] 12:50:45.214 [rmi tcp connection(3)-127.0.0.1] debug o.s.jndi.jndilocatordelegate -> located object jndi name [java:comp/env/user_name] 12:50:45.214 [rmi tcp connection(3)-127.0.0.1] debug o.s.jndi.jndipropertysource -> jndi lookup name [user_name] returned: [initech] 12:50:45.214 [rmi tcp connection(3)-127.0.0.1] debug o.s.c.e.propertysourcespropertyresolver -> found key 'user_name' in [jndiproperties] type [string] , value 'initech'

however, use @value annotation make code cleaner if @ possible; along lines of 

@bean public foo foo(         @value( "#{user_name}" ) string username,         @value( "#{user_password}" ) string userpassword     ){      return new foo( username, userpassword ); }

but code results in error:

nested exception org.springframework.expression.spel.spelevaluationexception: el1008e:(pos 0): property or field 'user_name' cannot found on object of type 'org.springframework.beans.factory.config.beanexpressioncontext' - maybe not public?; nested exception org.springframework.beans.factory.beanexpressionexception: expression parsing failed; nested exception org.springframework.expression.spel.spelevaluationexception: el1008e:(pos 0): property or field 'user_name' cannot found on object of type 'org.springframework.beans.factory.config.beanexpressioncontext' - maybe not public?; nested exception org.springframework.beans.factory.unsatisfieddependencyexception: error creating bean name 'oauthtokenrequestclient' defined in class path resource [com/initech/set/gw/api/config/gatewayrepositoryconfig.class]: unsatisfied dependency expressed through constructor argument index 0 of type [java.net.uri]: : expression parsing failed; nested exception org.springframework.expression.spel.spelevaluationexception: el1008e:(pos 0): property or field 'user_name' cannot found on object of type 'org.springframework.beans.factory.config.beanexpressioncontext' - maybe not public?; nested exception org.springframework.beans.factory.beanexpressionexception: expression parsing failed; nested exception org.springframework.expression.spel.spelevaluationexception: el1008e:(pos 0): property or field 'user_name' cannot found on object of type 'org.springframework.beans.factory.config.beanexpressioncontext' - maybe not public? org.springframework.beans.factory.support.constructorresolver.createargumentarray(constructorresolver.java:747) org.springframework.beans.factory.support.constructorresolver.instantiateusingfactorymethod(constructorresolver.java:462)

i have tried "#{systemenvironment.user_name}, "#{systemproperties.user_name}, "#{jndiproperties.user_name}, , "#{java:comp/env/user_name} well: yet, none of them work.

ps- i've tried simplify question if 1 of these should have worked let me know because may have made error in posting.

i solved using the selected answer question java spring: how use @value annotation inject environment property?.

so code looks like: 

@bean public foo foo(         @value( "#{environment.user_name}" ) string username,         @value( "#{environment.user_password}" ) string userpassword     ){      return new foo( username, userpassword ); }

i'm assuming content of the upvoted answer (ie "assuming have propertysourcesplaceholderconfigurer registered") quesiton means lacking configured propertysourcesplaceholderconfigurer.

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
