android调用springmvc写的restful

下载srpingmvc的相关jar

http://www.cnblogs.com/liuhongfeng/p/4919963.html

配置spingmvc和相关接口

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

如果报错，检查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;

/**
 * 用户管理
 * 
 * @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:视图层传给控制层的表单对象；model：控制层返回给视图层的对象
		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);
		Map map1 = 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中条码web调用接口的方法

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>







	

		

		
创建用户
			

				姓名： 
			
			

				年龄： 
			
			

				密码： 
			
			

				 
			
		
	
    

    	 
          
          
         
    

	GET00001

	GET0000100002
  
	GET0000100002
  

增加list.jsp文件

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>







${name}

如果在android中调用接口

增加权限

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

网络访问应该放在线程中
