Shiro认证登陆,授权

认证

两个shiro配置类

UserRealm

public class UserRealm extends AuthorizingRealm {

    @Autowired
    UserService userService;
    //授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        System.out.println("执行了=>授权doGetAuthorizationInfo");
        return null;
    }
    //认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        System.out.println("执行了=>认证doGetAuthorizationInfo");

        //连接真实数据库

        UsernamePasswordToken userToken=(UsernamePasswordToken)token;//取出前端form表单提交的
        User user = userService.queryByName(userToken.getUsername());//用前端提交的username对数据库做查询.

        if (user==null){
            return null;//抛出异常,对异常的处理在MyController中做MyController下面有
        }
        //密码认证shiro做
        //获取认证的用户
        Subject subject= SecurityUtils.getSubject();
        //封装用户的登陆数据
        return new SimpleAuthenticationInfo("",user.getPwd(),"");
    }
}

ShiroConfig

@configration

public class ShiroConfig{

//创建realm对象 ,需要自定义类:1
@Bean(name="userRealm")
public UserRealm userRealm(){
    return new UserRealm();
}

//defaultWebSecurityManager
@Bean(name="DWSM")
public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm")UserRealm userRealm){
    DefaultWebSecurityManager manager = new DefaultWebSecurityManager();
    //关联UserRealm
    manager.setRealm(userRealm);
    return manager;
}

@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("DWSM")DefaultWebSecurityManager defaultWebSecurityManager){
    ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
    //设置安全管理器
    bean.setSecurityManager(defaultWebSecurityManager);
    //shiro内置过滤器
    /*
    * anon无需认证就可以访问
    * authc:必须认证了才能访问
    * user:必须有记住我,才可以访问
    * perms 拥有对某个资源的权限才能访问
    * role: 拥有某个角色权限才能访问
    *
    * */
    LinkedHashMap<String, String> linkedHashMap = new LinkedHashMap<>();
    linkedHashMap.put("/user/add","authc");
    linkedHashMap.put("/user/update","authc");

    bean.setFilterChainDefinitionMap(linkedHashMap);
    bean.setLoginUrl("/tologin");
    return bean;
}

}

MyController

@Controller
public class MyController {


     

@RequestMapping("/login")
public String login(String username,String password,Model model){
    Subject subject= SecurityUtils.getSubject();
    UsernamePasswordToken token = new UsernamePasswordToken(username, password);
    try {
        subject.login(token);
        return "index";
    }catch (UnknownAccountException e){
        model.addAttribute("msg","用户名错误");
        return "login";
    }catch (IncorrectCredentialsException e){
        model.addAttribute("msg","密码错误");
        return "login";
    }

}

    @RequestMapping({"/","/index"})
    public String index(Model model){
        model.addAttribute("msg","hello,Shiro");
        return "index";
    }

    @RequestMapping("/user/add")
    public String add(){
        return "user/add";
    }
    @RequestMapping("/user/update")
    public String update(){
        return "user/update";
    }
    @RequestMapping("/tologin")
    public String tologin(){
        return "login";
    }

}

加入授权

数据库中加入了新字段perms用来规定角色具有的身份

1  刘明 123456  null

2 飞飞 123456 user:add

3 火华  123465 user:update

ShiroConfig    UserRealm  Mycontroller分别如下:

{

@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("DWSM")DefaultWebSecurityManager defaultWebSecurityManager){
    ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
    //设置安全管理器
    bean.setSecurityManager(defaultWebSecurityManager);
    //shiro内置过滤器
    /*
    * anon无需认证就可以访问
    * authc:必须认证了才能访问
    * user:必须有记住我,才可以访问
    * perms 拥有对某个资源的权限才能访问
    * role: 拥有某个角色权限才能访问
    *
    * */
    //拦截
    LinkedHashMap<String, String> linkedHashMap = new LinkedHashMap<>();
    //授权
    linkedHashMap.put("/user/add","perms[user:add]");
    linkedHashMap.put("/user/update","perms[user:update]");


    linkedHashMap.put("/user/*","authc");
    bean.setFilterChainDefinitionMap(linkedHashMap);
    //设置登陆的请求
    bean.setLoginUrl("/tologin");
    //未经授权的页面
    bean.setUnauthorizedUrl("/noauth");
    return bean;
}
//defaultWebSecurityManager
@Bean(name="DWSM")
public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm")UserRealm userRealm){
    DefaultWebSecurityManager manager = new DefaultWebSecurityManager();
    //关联UserRealm
    manager.setRealm(userRealm);
    return manager;
}


//创建realm对象 ,需要自定义类:1
@Bean(name="userRealm")
public UserRealm userRealm(){
    return new UserRealm();
}

}

package com.bootshiro.config;

        return new SimpleAuthenticationInfo(user,user.getPwd(),"");

    }
}

controller新增

@RequestMapping("/noauth")
@ResponseBody
public String unauthorized(){
    return "未经授权无法访问此页面";
}

几个页面

index.xml

<h1>首页</h1>
<p th:text="${msg}"></p>
<a th:href="@{/user/update}">update</a>
<br>
<a th:href="@{/user/add}">add</a>

login.html

<p th:text="${msg}"></p>
<form th:action="@{/login}">
  <p>用户名:</p><input type="text" name="username"><br>
  <p>密 码:</p><input type="password" name="password"><br>
  <input type="submit">
</form>

user文件夹下两个html

add.html

<h1>add</h1>

update.html

<h1>update<h1>
