Spring bean基于属性

Question

I am wondering if the below is possible in Spring

1. Read a property file using spring - this file has a list of jms queue names
2. Make spring loop on the above list and define beans that define Apache camel routes from that queue to a file

I could just create the routes using java code on the apache camel context, but wondering if it is possible through spring.

Answer 1

Reading a property file in a Spring XML wiring file is easy; eg using a PropertiesFactoryBean . However, the second part of the problem cannot (I believe) be solved without writing a significant amount of Java code.

I suggest that you read Section 3.8.3 of the Spring Reference that describes how to write your own FactoryBean classes. Another possibility is to create a custom Java configuration bean as described in Section 3.11 . There may be other possibilities too.

Warning: none of this stuff is particularly straight-forward if you are coming at it for the first time.
