(java)
We are developing Java Web software using SpringSTS on Eclipse 4.6.
When I transition from the first login screen to the next menu, jsp will run
The corresponding controller class GET method will not be executed.
I just need to fit the image for the title
I am not sure why it does not transition to the control class.
The relevant sources are as follows:

If you specify a string in the controller return value, you typically specify the path of View.
If you want to transition from one controller to another, use the forward.
To use forward, add forward: to the return string.
The path to getAMenu() in the AMenuController class is /AMenu in RequestMapping, so if you want to transition here, use forward:/AMenu as the return value.
However, if you use forward, the URL path displayed in the browser will be the original controller path (/ in this case).
If you want the URL displayed in your browser to be the path of the destination controller, use redirect in redirect:.
