Question

Can anyone advice me how can I inject multiple dependencies for a same bean in the spring framework?
I will try to explain the scenario very briefly, in case anyone can suggest me a better solution.

I have a data repository and it has to go through certain filters to filter out unwanted data. The criteria for filtering change and are not fixed to one filter. So, I created a filter handler which filters data based on filters. I want to use IoC and inject the filter dependencies. Its straight forward till here, only that there can be multiple filters. How do I inject multiple dependencies. If I can create a List of filters, how do I declare a list in the xml file?

Thanks in advance,

You can do it like this (filter1 and filter2 are ids of beans defined elsewhere):

<property name="propertyName">
  <list>
    <ref bean="filter1"/>
    <ref bean="filter2"/>
  </list>
</property>
