找回密码整体思路
//当点击找回密码的时候：
<a href="/login/forgot" target="_blank" id="btnForget" style="color: black; text-decoration: none;">找回密码</a>

//请求后台（login.java）返回页面（forgotPwd.ftl）
@RequestMapping("/forgot")
	public String forgot(HttpSession session, HttpServletRequest request,
			ModelMap map) {
		return "main/forgotPwd";
	}
	
//跳转到找回密码页面：(forgotPwd.ftl)
