Servlet的连接java后台

1.servlet代码

package com.bochiot.znys.servlet;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.bochiot.amain.HttpGyBossService;
import com.bochiot.amain.StringConst;
import com.bochiot.amain.WxConfiguration;
import com.bochiot.znys.config.ENUM_BOZHI_RESULT;
import com.project.util.L;

import net.sf.json.JSONObject;

public class longguanServlet extends BaseHttpServlet{
	public static String TAG = "longguanServlet";

	@Override
	protected void get(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		L.i(TAG, "start");
		// openID
		String openId = (String) request.getSession().getAttribute(StringConst.OPENID);
		L.i(TAG, "openId=" + openId);
		if (openId == null || "".equals(openId)) {
			if (WxConfiguration.istest) {
				openId = WxConfiguration.testopenid;
				L.i(TAG, "测试  openId=" + openId);
			} else {
				openId = request.getParameter("openId");
			}
		}

		JSONObject result = new JSONObject();
		result.put("code", -1);

		if (openId == null) {
			result.put("message", "未获取微信账户信息");
			super.out(response, result.toString());
			return;
		}

		L.i(TAG, "openId=" + openId);

		// 处理bindRoom.jsp页面中的数据请求
		String  hotelId= request.getParameter("hotelId");
		String roomno = request.getParameter("roomno");
		String roomname = request.getParameter("roomname");
		System.out.println("hotelId=" + hotelId);
		System.out.println("roomnum=" + roomno);
		System.out.println("roomname=" + roomname);

		ENUM_BOZHI_RESULT enum_BOZHI_RESULT = ENUM_BOZHI_RESULT.MSG_ERR_INVALID;
		try {
			result = HttpGyBossService.long_guan(openId, hotelId, roomno,roomname);
			enum_BOZHI_RESULT = ENUM_BOZHI_RESULT.getCODE(result.getInt("code"));

			if (enum_BOZHI_RESULT == ENUM_BOZHI_RESULT.MSG_SUCCESS) {
				L.d(TAG, "successed  "  + "hotelId: " + hotelId + "roomno: " + roomno
						+ " openId : " + openId);
				result.put("code", 0);
			} else {
				result.put("message", result.get("message"));
			}
		} catch (Exception e) {
			e.printStackTrace();
			result.put("message", e.getMessage());
		}
		super.out(response, result.toString());

	}// end

	@Override
	protected void post(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {

	}
}

2.service连接java后台地址

 

//长关
		public static String long_guan=WxConfiguration.URL_PREFIX+"api/gyboss/longguanPublic";

	//长关long_guan
					public static JSONObject long_guan(String openId,String hotelId, String roomno,String roomname) throws Exception {
						JSONObject info = new JSONObject();
						info.put("openId", openId);
						info.put("hotelId",hotelId);
						info.put("roomno",roomno);
						info.put("roomname",roomname);
						return HttpRequestUtils.sendCmdToServer(long_guan, info);
					}

3.对应java后台

//长关
	 	 		@RequestMapping(value = "/longguanPublic", method = RequestMethod.POST, consumes = "application/json")
	 	 		@ResponseBody
	 	 		public ApiResponseResult longguanPublic(@RequestBody EveryReq req) {
	 	 			RoomPublic r=roomPublicService.getRoomNo(Long.valueOf(req.getHotelId()),req.getRoomno());
	 	 			if(r.getDeviceId()==null||r.getGatewayInfo()==null) {
	 	 				return ApiResponseResult.failure("设备或网关未绑定");
	 	 				
	 	 			}
	 	 			Hotel h = hotelService.getHotel(Long.valueOf(req.getHotelId()));

	 	            SharePublic sharePublic=new SharePublic();
	 	 			sharePublic.setRoomNo(req.getRoomno());
	 	 			sharePublic.setRoomName(req.getRoomname());
	 	 			sharePublic.setHotel(h);
	 	 			String nano = System.nanoTime() + "";
	 	 		    sharePublic.setRequestid(Long.parseLong(nano.substring(nano.length() - 13)));
	 	 				// actiontype int 行为动作，0长关，1长开, 2 正常状态
	 	 				// devtype int 节点类型，0房间，1门禁
	 	 				try {
	 	 					super.dev_noc_set_Public(sharePublic, 0, 2);
	 	 				} catch (Exception e1) {
	 	 					// TODO Auto-generated catch block
	 	 					e1.printStackTrace();
	 	 					return ApiResponseResult.failure().message(e1.getMessage() );	
	 	 				}	

	 	 			return ApiResponseResult.success();
	 	 		}// ..

4.web.xml的映射配置

 <servlet>
    <servlet-name>longguanServlet</servlet-name>
    <servlet-class>com.bochiot.znys.servlet.longguanServlet</servlet-class>
  </servlet> 
  <servlet-mapping>
    <servlet-name>longguanServlet</servlet-name>
    <url-pattern>/bozhi/longguanServlet</url-pattern>
  </servlet-mapping>
