localization - Spring Framework - How to change locale in controller -

-

i new spring, , confusing localization. i'm using following code text messages_jp.properties file.

<bean id="messagesource" class="org.springframework.context.support.resourcebundlemessagesource">     <property name="basename" value="messages" /> </bean>

and want switch text messages_en.properties file, there ways change locale in controller within if...else... block, not using url params "?lang=en", like:

if (user.getlang() == 1) {     // set locale en } else {     // set locale jp }

thanks in advance!

try one

<util:properties id="yourfilenameid" location="classpath:/yourfilename.properties"/>

in controller

@value("#{yourfilenameid['message_id']?:1}") private int smalltext;

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()
