问题描述
是否可以使用从配置文件读取的属性来填充JMS选择器中的propertyValue?例如，我有:
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)
其中JMSSelector.ITEM_SELECTOR是一个字符串，定义为:
Where JMSSelector.ITEM_SELECTOR is a String defined as:
public static final String ITEM_SELECTOR = "type = 'S_TYPE' OR type = 'M_TYPE'"
假设我除了"S_TYPE"和"M_TYPE"之外还有另一种新类型，并且在配置文件中有它
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
有没有一种方法可以动态加载它，而无需修改我的代码并重新部署它?
Is there a way to load it dynamically without modifying my code and redeploy it?
推荐答案
我将回答我自己的问题，因为jmsselector字符串是静态的，所以没有找到从配置文件中进行动态读取的方法.否则我发现了这个 https://timjansen.github.io/jarfiller/guide/jms/selectors. xhtml ，而我的解决方案是
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'"
