1.JSP和Servlet傳值通過客戶端到伺服器會出現亂碼現象.

2.關於解決Servlet表單傳值Get和Post亂碼的解決.

         2.1  doget的解決,先建一個工具類,便於呼叫轉碼成utf-8,靜態方法便於呼叫.

public class MyUTF {

	//封裝成工具類
	   public static String getNewString(String str) throws UnsupportedEncodingException
	    {
	       return new String(str.getBytes("ISO-8859-1"),"UTF-8");
	    }
}
 

                      2.1.2     Servle裡的程式碼呼叫.

public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {

		//解決亂碼
		response.setContentType("text/html;charset=utf-8");
		
	
		//獲取介面的資料   使用封裝的方法
		String name=MyUTF.getNewString(request.getParameter("name"));
		
		
		
		//定義輸出!
		PrintWriter out = response.getWriter();
		out.println(name);
		out.println("你好,我是doGet!");
		
	}
 

           結果:

           2.2   doPost的亂碼解決.

                   2.2.1  客戶端的post請求相對簡單,直接在Servlet裡新增轉換的程式碼.

public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {

		//解決中文亂碼
		response.setContentType("text/html;charset=utf-8");
		//請求解決亂碼
		request.setCharacterEncoding("utf-8");
		//響應解決亂碼
		response.setCharacterEncoding("utf-8");
		//輸出
		PrintWriter out = response.getWriter();
		String  name=request.getParameter("name");
		
		out.println(name);
		out.println("你好!我是doPost!");
	}
