• 与客户端对接用户信息的保存方式



    在日常开发中，少不了与客户端进行通信，然而一些用户数据是怎么保存比较好的呢


    1.保存在服务器端 传给客户端sessionid ,客户端每次之后每次请求都需要传入该sessionid,服务器验证

    1. //调用
    2. httpPost.setHeader("Cookie", "JSESSIONID=2F616197147E641684F30570028E4535");
    3. //处理
    4. public ActionForward clientmanage(ActionMapping mapping, ActionForm form,
    5. 	    HttpServletRequest request, HttpServletResponse response)throws Exception {
    6. 		response.setCharacterEncoding("utf-8");
    7. 		
    8. 		//保存xml传过来的参数
    9. 		Map<String,String> inputMap = new HashMap<String, String>();
    10. 		Map<String,Object> xmlMap=new HashMap<String, Object>();
    11. 		//标识
    12. 		String tflag = "";
    13. 		//返回xml
    14. 		String xml = "";
    15. //		StringBuffer sb = new StringBuffer();
    16. 		
    17. 		
    18. 		
    19. 		BufferedReader br = null;
    20. 		String xmlstr = request.getParameter("xml");
    21. 		//解析xml
    22. 		try{
    23. 			SAXReader reader = new SAXReader();  
    24. 			
    25. //			BufferedReader reReader = request.getReader();
    26. //			
    27. //			String line=reReader.readLine();
    28. //			while(line!=null){
    29. //				sb.append(line);
    30. //				line=reReader.readLine();
    31. //			}
    33. //			reReader.reset();
    34. 			//HTTP请求
    35. 			if(!StringUtils.isEmpty(xmlstr)){
    36. 				ByteArrayInputStream bos = new ByteArrayInputStream(xmlstr.getBytes());
    37. 				InputStreamReader ir = new InputStreamReader(bos);
    38. 				br = new BufferedReader(ir);
    39. 			}else{
    40. 				br = request.getReader();
    41. 			}
    42.

    44. 			
    45. 			Element root  =  document.getRootElement(); //  得到根节点  
    46. 			for(Element e : (List<Element>)root.elements()){
    47. 				inputMap.put(e.getName(), e.getTextTrim());
    48. 				xmlMap.putAll(XmlParserUtil.parseXml(e,true));
    49. 			}
    51. 			System.out.println("get------"+inputMap);
    52. 			
    53.             //客户手机类型
    54.             String clientType = request.getParameter("client");
    55.             inputMap.put("client",StringUtils.isEmpty(clientType) ? "" : clientType);
    57. 			//保存sessionid
    58. 			inputMap.put("sessionid", request.getSession().getId());

    2.存入客户端，这个可以缓存到客户端数据库 比如sqlite 登录状态的话用户可以手动清理 (android源码中有)
