shiro
shiro認證,鹽加密
整合ssm和shiro
導入pom依賴

逆向生成ShiroUser,此處的代碼就不一 一發出來了
ShiroUserService
package com.lst.service;
import com.lst.model.ShiroUser;
/**
* @create 2019-10-13 16:12
*/
public interface ShiroUserService {
/**
* 用於shiro認證的
* @param uname
* @return
*/
public ShiroUser queryByName(String uname);
/**
* 用於註冊用戶
* @param shiroUser
* @return
*/
int insertUser(ShiroUser shiroUser);
}
MyRealm,調用queryByName獲取用戶信息,然後對用戶名和密碼進行判斷

import com.lst.model.ShiroUser;
import com.lst.service.ShiroUserService;

* 2.2、鹽加密

註冊界面效果:
我們在界面上輸入的密碼是‘123’,但是存在數據庫內的密碼是經過加密後的隨機字符串
