Misleading alias definition example in reference documentation, part 1.3.1 [SPR-17536]

[spring-projects-issues]

Amir Pashazadeh opened SPR-17536 and commented

In the later example documentation describes a situation for Subsystem A and SubSystem B, the example must perform the same thing on both, but it does not. I believe its some typo in the example XML, and must become:
 

<alias name="subsystemA-dataSource" alias="myApp-dataSource"/>
<alias name="subsystemB-dataSource" alias="myApp-dataSource" />

It's actually meant to be as follows, aliasing both subsystem references to the main app bean, so that myApp-dataSource is the only bean actually defined in the overall configuration:

<alias name="myApp-dataSource" alias="subsystemA-dataSource"/>
<alias name="myApp-dataSource" alias="subsystemB-dataSource"/>

Thanks for spotting this!
