问题
Is there a way to use a property read from a config file to fill propertyValue in JMS selector? As an example I have:
@ActivationConfigProperty(propertyName = "messageSelector", propertyValue =
JMSSelector.ITEM_SELECTOR)
Where JMSSelector.ITEM_SELECTOR is a String defined as:
public static final String ITEM_SELECTOR = "type = 'S_TYPE' OR type = 'M_TYPE'"
Let's say that I have another new type other than "S_TYPE" and "M_TYPE", and I have it in a config file
MYTYPES = S_TYPE,M_TYPE,G_TYPE
Is there a way to load it dynamically without modifying my code and redeploy it?
回答1:
I'll answer my own question, I didn't find a way to dinamically read from a config file because jmsselector String is static. Otherwise I found this https://timjansen.github.io/jarfiller/guide/jms/selectors.xhtml and my solution is
public static final String ITEM_SELECTOR = "'tipe LIKE '%_TYPE'"
hope someone will be pleased
