1 struts1 框架搭建
在myeclipse新建web project 取名為struts1_login，此時是一個空文檔就不截圖了然后在project上右鍵->選擇myeclipse->add struts capabilities
單擊上面install apache struts(1.x)facet
點擊next
選擇*.do ，改下包名改成與你項目相關的。如我的包名為com.lichang.struts1
點擊next
點擊完成，在我們的web-inf下就會多出struts-config.xml文件
以上就是讓myeclipse幫我們加入框架的大概過程。項目的整體結(jié)構(gòu)如下：
至此我們的struts1 框架搭建完成2 接著我們就開始編程來實現(xiàn)了。
