如何在apache camel + spring中动态加载属性文件值

Question

I am a newbie using camel 2.17 with spring. I have a processor which receives an error code from a web service and I configured the error description in the property file like

  myproject.errorCode=1001:error1 description, 1002:error2 description, 1003:....

Currently I am reading the value myproject.errorCode using property injection and parsing all the errorCode with description which is working fine. But the error code list is very huge and maintaining it in a single property is very difficult. So I want to split the properties like

   myproject.errorCode.1001=error1 description
   myproject.errorCode.1002=error2 description
   myproject.errorCode.1003=error3 description
   .....

and I want to read the property in my processor class according to the error code received from the web service like

  String errorCodeRecieved  = myWebService.getErrorCode();
  String errorString = "myproject.errorCode.";
  String errorDescription = something.getProperty(errorString + errorCodeRecieved);

How can I achieve this facility. Thanks in advance

Answer 1

you can make a MessageSource available in your context,

@Bean
MessageSource myMessageSource() {
    ResourceBundleMessageSource r = new ResourceBundleMessageSource();
    r.setBasenames("/messages/sample");
    r.setDefaultEncoding("UTF-8");
    return r;
}

And then use this in your processor to fetch the appropriate message like:

messageSource.getMessage(code, null, null, locale)
