自研框架文档:
-
新建一个maven项目命名为simpleFramework
-
在java目录下新建com.bear包
-
main同级新建webapp/WEB-INF/jsp
-
hello.jsp文件
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>Title</title> </head> <body> <h2>${name}</h2> </body> </html>
@WebServlet("/hello")
public class Demo extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
String name = "我的第一个spring框架";
req.setAttribute("name",name);
req.getRequestDispatcher("/WEB-INF/jsp/Hello.jsp").forward(req,resp);
}
}
