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);
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中条码web调用接口的方法
Insert title here
${name}
如果在android中调用接口
增加权限
网络访问应该放在线程中
