Spring transactions - this mode is applied when both are specified in the config

I was trying to debug a legacy code issue and accidentally realized that the spring config file configures the transaction manager in both aspect and proxy mode.

<tx:annotation-driven transaction-manager="txManager" proxy-target-class="true"/>
<tx:annotation-driven transaction-manager="txManager" mode="aspectj"/>

      

        
        
        
      

    

These configurations are located in different xml files. Which mode will the application choose? Does it depend on the ordering, or is there one mode that overrides the other? Thank!
