Target:

In velocity files, we visite international resource which was stored in DB by used some methods!

Key Words:

Velocity , Spring , messagesource , Synyx Messagesource for Spring

Reference:

http://redmine.synyx.org/projects/messagesource/wiki

Getting Start:

configure in Maven(down related package):

<repositories>
.......

  <repository>
         <id>nexus.synyx.org</id>
         <name>Synyx OpenSource Repository</name>
         <url>http://repo.synyx.org</url>
     </repository>
</repositories>

<dependencies>
<dependency>
            <groupId>org.synyx</groupId>
            <artifactId>messagesource</artifactId>
            <version>0.6.1</version>
        </dependency>
</dependencies>

Configue in application context:

Read reource by messageSourceAccessor:

MessageSource messageSource = (MessageSource) applicationContext.getBean("messageSource");
MessageSourceAccessor messageSourceAccessor = new MessageSourceAccessor(messageSource);

Create a helper class to read resource for DB

calss MessageTool {

..........................

public String get(String code) {
return messageSourceAccessor.getMessage(code, locale);
}

    public String get(String code, String s1) {
        return messageSourceAccessor.getMessage(code, s1, locale);
    }

    public String get(String code, Object[] args) {
        return messageSourceAccessor.getMessage(code, args, locale);
    }

    public String get(String code, Object[] args, String defaultMsg) {
        return messageSourceAccessor.getMessage(code, args, defaultMsg, locale);
    }

    public String get(String code, List args) {
        return this.get(code, args.toArray());
    }

    public String get(String s, String s1, List list) {
        return this.get(s, list.toArray(), s1);
    }

}

Finnally, we can use following writing to read resource file:

$messageTool.get('VELOCITY')

if current locale is en_US, the tool will query special message by follow conditions: language=en and country=US and key=VELOCITY!
