配置spingmvc和相關接口

http://blog.csdn.net/jianyuerensheng/article/details/51258942

如果報錯，檢查JDK版本是否和本地的一致

在UserController.jave中添加接口

package com.zjn.controller;

import java.util.HashMap;

import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;

import org.springframework.ui.Model;

import org.springframework.web.bind.annotation.ModelAttribute;

import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RequestParam;

import org.springframework.web.bind.annotation.ResponseBody;

import org.springframework.web.servlet.ModelAndView;

import com.zjn.entity.User;

/**

* 用戶管理

*

* @author zjn

*/

@Controller

public class UserController {

@RequestMapping("")

public String Create(Model model) {

return "create";

}

@RequestMapping("/save")

public String Save(@ModelAttribute("form") User user, Model model) { // user:視圖層傳給控制層的表單對象；model：控制層返回給視圖層的對象

model.addAttribute("user", user);

return "detail";

}

@RequestMapping(value="/Restfull",method=RequestMethod.POST)

public String Restfull(@ModelAttribute("form") User user, HttpServletRequest request,HttpServletResponse response) throws Exception {

request.setAttribute("name",user.getAge()+ user.getName() + user.getPwd());

return "list";

}

@RequestMapping(value="/RestfullGet/{proId}",method=RequestMethod.GET)

public String RestfullGet(@PathVariable String proId, HttpServletRequest request,HttpServletResponse response) throws Exception {

request.setAttribute("name", proId);

return "list";

}

@RequestMapping(value="/RestfullMGet/{name}/{pwd}",method=RequestMethod.GET)

public String RestfullMGet(@ModelAttribute("form") User user, HttpServletRequest request,HttpServletResponse response) throws Exception {

request.setAttribute("name", user.getName() + "------" + user.getPwd());

return "list";

}

@RequestMapping(value="/RestfullM1Get/{name}/{pwd}",method=RequestMethod.GET)

public ModelAndView RestfullM1Get(@PathVariable String name,

@PathVariable String pwd) {

System.out.println(name + "------" + pwd);

Mapmap1 = new HashMap();

map1.put("name", name + "------" + pwd);

return new ModelAndView( "/list", map1);

}

@RequestMapping(value="/RestfullAGet/{proId}",method=RequestMethod.GET)

public @ResponseBody String RestfullAGet(@PathVariable String proId, HttpServletRequest request,HttpServletResponse response) throws Exception {

request.setAttribute("name", proId);

return "backinfo:" + proId;

}

}

在create.jsp中條碼web調用接口的方法

Insert title here

${name}

如果在android中調用接口

增加權限

網絡訪問應該放在線程中
