学习若依框架----之----获取登录登录系统、ip、浏览器信息

若依里面，创建登录日志是根据异步任务进行新增，设置的有一个延时任务，登录之后，创建登录日志。本文章是非异步任务新增。大概思路是：在登录、注册、退出登录完成返回之前，调用日志工具，进行新增日志操作。

备注：
重点是日志工具逻辑，先判断是不是内网，然后获取IP地址，根据IP地址获取地址信息，使用浏览器依赖获取到浏览器信息，这些信息组合成登录信息，在日志工具使用springUtils获取日志service服务bean，调用日志service服务新增。

主要学习是工具是：
IPutils（获取IP）
addressUtil（获取地址信息）
UserAgent（获取浏览器信息）
SpringUtils（获取bean）

本方法是非异步任务：

6.使用

public Res login(LoginBody loginBody) {
        //0登录成功，1登录失败，2注册成功，3退出登录
        if (loginBody.getStatus() == 0) {
            LogUtil.saveLoginInfo(loginBody.getUsername(), Constants.LOGIN_SUCCESS,"登录成功");
            return Res.success("登录成功");
        }else if (loginBody.getStatus()==1){
            LogUtil.saveLoginInfo(loginBody.getUsername(), Constants.LOGIN_FAIL,"登录失败");
            return Res.success("登录失败");
        }else if (loginBody.getStatus()==2){
            LogUtil.saveLoginInfo(loginBody.getUsername(), Constants.REGISTER,"注册成功");
            return Res.success("注册成功");
        }else if (loginBody.getStatus()==3){
            LogUtil.saveLoginInfo(loginBody.getUsername(), Constants.LOGOUT,"退出成功");
            return Res.success("退出成功");
        }
        return Res.error("异常");
    }
