将Token写入Cookie服务层做不到,只能由表现层来做.

//根据用户名查询用户信息
TbUserExample example = new TbUserExample();

//执行查询
List<TbUser> list = userMapper.selectByExample(example);
if (list == null || list.size() == 0) {
//返回登录失败
return E3Result.build(400, "用户名或密码错误");
}
//取用户信息
TbUser user = list.get(0);
//判断密码是否正确
if (!DigestUtils.md5DigestAsHex(password.getBytes()).equals(user.getPassword())) {
// 2、如果不正确,返回登录失败
return E3Result.build(400, "用户名或密码错误");
}
// 3、如果正确生成token。
String token = UUID.randomUUID().toString();
// 4、把用户信息写入redis,key:token value:用户信息
user.setPassword(null);
jedisClient.set("SESSION:" + token, JsonUtils.objectToJson(user));
// 5、设置Session的过期时间
jedisClient.expire("SESSION:" + token, SESSION_EXPIRE);
// 6、把token返回
return E3Result.ok(token);
}
