Spring Freemarker绑定-什么是控制器？

Question

looking at the documentation for the spring macros for freemarker they talk about the 'command' object... i am confused as to what that is? at first i thought it is just the ModleMap set by the controller, but its obviously not. What is the "bind" actually used for?

Answer 1

The command object it's referring to is the form-backing object used by Spring MVC. If you want to use full form handling, I strongly suggest you go and read up on the rest of the Spring MVC documentation before tackling it.

However, you can safely ignore the form-handling stuff if you so choose, and just access the ModelMap directly from your freemarker templates.
