SPRINGMVC parameter Passing (i)

1. Project structure

2.usercontroller.java Code

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 classUsercontroller {@RequestMapping (value="/add.do", method=requestmethod.post) Publicstring Add (HttpServletRequest request, HttpServletResponse response,httpsession session) {string US Ernum=request.getparameter ("Usernum"); String PassWord=request.getparameter ("PassWord"); System. out. println ("----Add user information----"); System. out. println ("User name:"+usernum); System. out. println ("Password::"+PassWord); return "user/success"; } @RequestMapping (Value="/add1.do", method=requestmethod.post) Publicstring Add1 (httpservletrequest request, HttpServletResponse response,httpsession session) {string Usernum=request.getparameter ("Usernum"); String PassWord=request.getparameter ("PassWord"); System. out. println ("----Add user information----"); System. out. println ("User name:"+usernum); System. out. println ("Password::"+PassWord); return "user/success"; } @RequestMapping (Value="/add2.do", method=requestmethod.post) Publicstring add2 (string username,string password) {System. out. println ("----Add user information----"); System. out. println ("User name:"+username); System. out. println ("Password::"+password); return "user/success"; } @RequestMapping (Value="/add3.do", method=requestmethod.post) PublicString add3 (@RequestParam (value="username") String username,integer password) {System. out. println ("----Add user information----"); System. out. println ("User name:"+username); System. out. println ("Password::"+password); return "user/success"; }    }

Note: There is no need for type conversion when you pass a parameter, SPRINGMVC automatic conversion
