解决客户端重定向，URL地址中文乱码的问题。nameString = URLEncoder.encode(nameString, "utf-8");

先通过表单向后台递交数据

数据递交到AddUser这个servlet之后，获取username，将username的值作为参数放在重定向地址的后面。按照下面的代码来写的话，，如果username是中文，重定向的url是：http://localhost:8080/servlet_06/AddUserSuccess?username=??

解决的办法是：将地址后面的nameString先做一下处理。加入一句：nameString = URLEncoder.encode(nameString, "utf-8");即可

public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		request.setCharacterEncoding("UTF-8");
		response.setCharacterEncoding("UTF-8");
		String nameString=request.getParameter("username");
		String contextPath=request.getContextPath();
		System.out.println(contextPath);
		System.out.println(nameString);

		//nameString = URLEncoder.encode(nameString, "utf-8");
		response.sendRedirect(contextPath+"/AddUserSuccess?username="+nameString);
	}
