这篇文章主要介绍了SpringBoot登录判断代码实例,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
<!-- html登录代码 --> <div class="box"> <div class="title">登录</div> <div class="input"> <label for="name">用户名</label> <input type="text" name="name" > <span class="spin"></span> </div> <div class="input"> <label for="pass">密码</label> <input type="password" name="pass" > <span class="spin"></span> </div> <div class="button login"> <button> <span>登录</span> <i class="fa fa-check"></i> </button> </div> <a href="javascript:" rel="external nofollow" class="pass-forgot">忘记密码?</a> </div>
<!-- javasript 登录代码 --> $(".button").click(function(e) { $("button", this).addClass('active'); if ($(".button").hasClass("login")){ $.ajax({ url:"/cch/dologin", type:"POST", data:{ name:$("#name").serialize(), pass:$("#pass").serialize(), }, success:function (result) { if(result.code==100){ window.location.href="/cch/main" rel="external nofollow" ; }else { alert(result.extendInfo.login_error); } } }) } })
//JsonMsg工具类 public class JsonMsg { private int code; private String msg; private Map<String,Object> extendInfo = new HashMap<String, Object>(); public int getCode() { return code; } public void setCode(int code) { this.code = code; } public String getMsg() { return msg; } public void setMsg(String msg) { this.msg = msg; } public Map<String, Object> getExtendInfo() { return extendInfo; } public void setExtendInfo(Map<String, Object> extendInfo) { this.extendInfo = extendInfo; } public static JsonMsg success(){ JsonMsg res = new JsonMsg(); res.setCode(100); res.setMsg("操作成功"); return res; } public static JsonMsg fail(){ JsonMsg res = new JsonMsg(); res.setCode(200); res.setMsg("操作失败"); return res; } public JsonMsg addInfo(String key,Object object){ this.extendInfo.put(key,object); return this; } }
/** * controller * 判断用户名和密码是否正确 */ @RequestMapping(value = "/cch/dologin",method = RequestMethod.POST) @ResponseBody public JsonMsg dologin(HttpServletRequest request){ String username = request.getParameter("name"); String password = request.getParameter("pass"); System.out.println(username+" "+password); if (!"name=admin".equals(username) || !"pass=123".equals(password)){ return JsonMsg.fail().addInfo("login_error","用户名或密码错误"); } request.getSession().setAttribute("islogin","true");//如果正确,则在seesion里添加判断属性,可供拦截器判断是否登录过 return JsonMsg.success(); }
