JSP不同線程導致對象改變樣本

 

代碼如下

複製代碼

<%         final HttpServletRequest  f = request;         System.out.println("sdaddsdasdsd");         new Thread()         {             public void run()             {                 RequestDispatcher rd;                 try                 {                     f.setCharacterEncoding("gb2312");                 }                 catch (Exception e)                 {                     e.printStackTrace();                 }                 String SiteName = f.getParameter("SiteName");                 String Name = f.getParameter("Name");                 String userAccount = f.getParameter("userAccount");                 String userPasswd = f.getParameter("userPasswd");                 String databaseAddress = f.getParameter("databaseAddress");                 String databaseName = f.getParameter("databaseName");                 String databaseAccount = f.getParameter("databaseAccount");                 String databasePasswd = f.getParameter("databasePasswd");                                                     System.out.println(SiteName);                 System.out.println(Name);                 System.out.println(userAccount);                 System.out.println(userPasswd);                 System.out.println(databaseAddress);                 System.out.println(databaseName);                 System.out.println(databaseAccount);                 System.out.println(databasePasswd);                                           new org.Rudiment.Blog.Install(SiteName, userAccount, userPasswd, Name, databaseAddress, databaseName, databaseAccount, databasePasswd, f);             }         }.start();             %>

Sysyem.out.println() 全部都是null

如果放在Thread外面就可以獲得值，這個以後再研究。研究出來的共用一下。
