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.  publicActionForward 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();`

**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)**
