这个dopost有问题吗

	public void doPost(HttpServletRequest request, HttpServletResponse response)

			throws ServletException, IOException {

		     PrintWriter out = response.getWriter();

		    out.println("测试");

			request.setCharacterEncoding("utf-8");

			String username = request.getParameter("username");

			String password = request.getParameter("password");

			System.out.println("转发！");

			if(username=="Wone"&&password=="690109wwh"){

				System.out.println("正在正确进行重定向");

				response.sendRedirect("/Login2.0/page/suc.jsp");

			}else{

				System.out.println("正在错误进行重定向");

				response.sendRedirect("/Login2.0/page/eor.jsp");

			}

为什么地址栏可以跳转到这个Servlet 却不会进行重定向。也不会向网页写入任何内容。Sys.o也没有出现。错哪里了？
