token的保存和获取，本次说的方法只是其中一种，案例简单，后续复杂性可自行优化

function checkForm() {

var oUser = document.getElementById('user');

var oPswd = document.getElementById('pwd');

if(remember.checked) {

setCookie('user', oUser.value, 90); //保存帐号到cookie，有效期7天

setCookie('pwd', oPswd.value, 90); //保存密码到cookie，有效期7天

}

$.ajax({

url: "/loginauth/login",

type: "post",

dataType: "json",

/*指定ajax和servlet之间数据交互的格式*/

data: {

userName: oUser.value,

password: oPswd.value,

ip:queryIp()

},

async: true,

success: function(result) {

if (result.code==100){

var token=result.token

document.cookie=token;

window.location.href = "/index?token="+token;

}

}

});

//************************

}

@RequestMapping("/loginauth/login")

@ResponseBody

public Map loginAuth(String userName, String password){

Map result=new HashMap<>();

if ("admin".equals(userName)&&"123".equals(password)){

result.put("code","100");

result.put("token",userName+""+password);

result.put("message","登录成功");

return result;

}

result.put("code","-100");

result.put("message","登录失败");

return result;

}

@RequestMapping("/home")

@ResponseBody

public Map home(@RequestHeader Map headers,HttpServletRequest request ){

headers.forEach((key,value)->{

//logger.info(key+","+value);

});

String token=request.getHeader("access-token");

logger.info("token:{}",token);

Map map=new HashMap<>();

if (StringUtils.isEmpty(token)){

map.put("code","-100");

map.put("message","token获取失败");

}

map.put("code","100");

map.put("message","token获取成功,token="+token);

return map;

}

以上就是本次的全部代码
