shiro认证后获取登录用户信息

矫情吗；* 2023-06-20 15:52 14阅读 0赞

1、shiro.xml配置认证成功跳转路径后再该方法中：

/** * shiro认证后获取用户信息进入首页 * @param model * @return */
        @RequestMapping("index.do")
        public String index(Model model){ 
            Subject subject = SecurityUtils.getSubject();
            /** * 说明： * 1、之所以能转成User，是在shiro的doGetAuthenticationInfo认证时传入的是user； * 2、认证的实体类User必须实现序列化接口，并提供版本号 * 3、若传入的是username，则只能获取到username */
            User user = (User)subject.getPrincipal();
            System.out.println(user.getId()+"========="+user.getUsername()+"============"+user.getPassword());
            model.addAttribute("username",user.getUsername());
            return "/models/sys/index";
        }

2、自定义Realm中

/** * 认证 * @param token * @return * @throws AuthenticationException */
        @Override
        protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { 
            //token获取登录输入用户信息
            String userName = token.getPrincipal().toString();
    
            SimpleAuthenticationInfo info = null;
            try { 
                if(loginService==null){ 
                    loginService = SpringBeanFactoryUtils.getBean(LoginService.class);
                }
                User user = loginService.getTokenByUser(userName);
                info = new SimpleAuthenticationInfo(**user**, user.getPassword(),ByteSource.Util.bytes(user.getSalt()), getName());
            }catch (Exception e){ 
                e.printStackTrace();
            }
            return info;
        }

3、实体类

public class User implements Serializable { 
        private static final long serialVersionUID = 1L;
        private String id;
        private String username;
        private String password;
        private String salt;
    }
