1.项目结构
2.UserController.java代码
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("----添加用户信息----");
System.out.println("用户名："+userNum);
System.out.println("密码：："+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("----添加用户信息----");
System.out.println("用户名："+userNum);
System.out.println("密码：："+passWord);
return "user/success";
}
@RequestMapping(value="/add2.do",method=RequestMethod.POST)
public String add2(String username,String password){
System.out.println("----添加用户信息----");
System.out.println("用户名："+username);
System.out.println("密码：："+password);
return "user/success";
}
@RequestMapping(value="/add3.do",method=RequestMethod.POST)
public String add3(@RequestParam(value="username")String username,Integer password){
System.out.println("----添加用户信息----");
System.out.println("用户名："+username);
System.out.println("密码：："+password);
return "user/success";
}
}
注：传参时不必进行类型转换，SpringMVC自动转换
2.视图层代码
