java中对cookie的简单处理

1. class
2. {
3. publicActionForwardindex(ActionMappingmapping,ActionFormform,
4. HttpServletRequestrequest,HttpServletResponseresponse){
6. Cookie[]cookies=request.getCookies();
7. if(null==request.getSession().getAttribute("userMsg")){
8. if(cookies!=null){
9. booleancookie=false;
10. StringuserName="";
11. for(inti=0;i<cookies.length;i++){
12. if(cookies[i].getName().equals("boyin")){
13. userName=cookies[i].getValue();
14. cookie=true;
15. break;
17. }
18. }
19. if(cookie=true){
21. //业务处理
22. }
23. }
24. }
25. returnmapping.findForward("builderIndex");
27. }
28. }
30. //写cookie
32. Cookienewcookie=newCookie("name",userName1);
33. newcookie.setDomain("boyincn.com");
34. newcookie.setMaxAge(60*60);
35. response.addCookie(newcookie);
