Label: style HTTP color Io OS SP problems on In (1), I only introduced how to access an action and its ing page. In actual development, we are more about accessing a method of an action, this article will discuss this issue When learning struts, I believe everyone will come up with two ways to write the access action method: 1. Use it! Specify dynamically 2. Use wildcards for Dynamic Matching: Becau

In the Struts 2 app, the view page can directly access the action's properties via the tag (in fact, it's an illusion, like a web app that maintains a 4-range "bank" of application, Session, request, page).

A few days ago, I wrote a simple struts example about user login. I think it is necessary to take a closer look at the struts workflow. Here we use the above example to describe the process of performing form verification on the server. (Hey hey, I just learned this. please correct me more about the mistakes.)
