Controllerclassnamehandlermapping configuration failed

I have read a lot of materials and have conducted many examples on the Internet, that is, using controllerclassnamehandlermapping fails.

 

It turns out that it was related to the initialization sequence of controllerclassnamehandlermapping. You must specify the initialization sequence of controllerclassnamehandlermapping before the Controller initialization, this may be a bug in spring2.5.6.

 

 

The initialization sequence can be as follows:

 

<Bean class = "org. springframework. Web. servlet. MVC. Support. controllerclassnamehandlermapping">

</Bean>

<Bean class = "com. mkyong. Common. Controller. welcomecontroller"/>

<Bean class = "com. mkyong. Common. Controller. helloguestcontroller"/>
