1.項目結構
2.UserController.java代碼
package com.spring; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpSession; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RequestParam; @Controller/*@RequestMapping("/user")*/ public class UserController { @RequestMapping(value="/add.do",method=RequestMethod.POST) public String add(HttpServletRequest request, HttpServletResponse response,HttpSession session){ String userNum=request.getParameter("userNum"); String passWord=request.getParameter("passWord"); System.out.println("----添加用戶信息----"); System.out.println("用戶名："+userNum); System.out.println("密碼：："+passWord); return "user/success"; } @RequestMapping(value="/add1.do",method=RequestMethod.POST) public String add1(HttpServletRequest request, HttpServletResponse response,HttpSession session){ String userNum=request.getParameter("userNum"); String passWord=request.getParameter("passWord"); System.out.println("----添加用戶信息----"); System.out.println("用戶名："+userNum); System.out.println("密碼：："+passWord); return "user/success"; } @RequestMapping(value="/add2.do",method=RequestMethod.POST) public String add2(String username,String password){ System.out.println("----添加用戶信息----"); System.out.println("用戶名："+username); System.out.println("密碼：："+password); return "user/success"; } @RequestMapping(value="/add3.do",method=RequestMethod.POST) public String add3(@RequestParam(value="username")String username,Integer password){ System.out.println("----添加用戶信息----"); System.out.println("用戶名："+username); System.out.println("密碼：："+password); return "user/success"; } }
註：傳參時不必進行類型轉換，SpringMVC自動轉換
2.視圖層代碼
