springboot配置shrio

1导入依赖

<dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
            <version>1.7.1</version>
        </dependency>

配置shrio配置类 以及配置类中的UserRealm

@Configuration
public class ShiroConfig {
    //创建 ShiroFilterFactoryBean
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager")DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
        //设置安全管理器
        bean.setSecurityManager(defaultWebSecurityManager);
        //添加内置过滤器
        /* 添加Shiro内置过滤器，常用的有如下过滤器：
         anon： 无需认证就可以访问
         authc： 必须认证才可以访问
         user： 如果使用了记住我功能就可以直接访问
         perms: 拥有某个资源权限才可以访问
         role： 拥有某个角色权限才可以访问
         */
        Map<String, String> filterMap=new LinkedHashMap<>();
        //授权过滤器 正常的情况下会跳转到未授权界面
        filterMap.put("/user/add","perms[user:add]"); //大家记得注意顺序！
        filterMap.put("/user/update","perms[user:update]");
        bean.setFilterChainDefinitionMap(filterMap);
        //设置登录的请求
//        bean.setLoginUrl("/toLogin");
        bean.setUnauthorizedUrl("/noauth");
        return bean;
    }




    // 创建 DefaultWebSecurityManager
    @Bean(name="securityManager")
    public DefaultWebSecurityManager getDefaultWebSecurityManager (@Qualifier("userRealm")UserRealm userRealm){
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        //关联Realm
        securityManager.setRealm(userRealm);
        return securityManager;
    }



    // 创建 realm 对象
    @Bean
    public UserRealm userRealm(){
        return new UserRealm();
    }
    @Bean
    //配置ShiroDialect：方言，用于 thymeleaf 和 shiro 标签配合使用
    public ShiroDialect getShiroDialect(){
        return new ShiroDialect();
    }
}

自定义realm

public class UserRealm  extends AuthorizingRealm {
    @Autowired
    UserService userService;
    //自定义realm
    //执行授权逻辑
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("执行了=>授权逻辑PrincipalCollection");
        //给资源进行授权
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();

        //拿到当前登录的对象
        Subject subject = SecurityUtils.getSubject();
        //拿到User对象
        User currentUser = (User) subject.getPrincipal();
        //设置当前用户的权限
        info.addStringPermission(currentUser.getPerms());

        return info;
    }
    
    //执行认证逻辑
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        System.out.println("执行了=>认证逻辑AuthenticationToken");
        //用户名 密码 数据库取
        //连接真实数据库
        System.out.println("看看Principal里是什么 哦 他是："+token.getPrincipal());

        UsernamePasswordToken userToken = (UsernamePasswordToken)token;

        User user = userService.queryUserByName(userToken.getUsername());
        if (user==null){
            //没有这个人
            return null;
        }
        //密码认证shiro自己做
        return new SimpleAuthenticationInfo(user,user.getPwd(), "");
    }

}

另外一个更完整的realm

public class UserRealm extends AuthorizingRealm {
    // 用户对应的角色信息与权限信息都保存在数据库中，通过UserService获取数据
    private UserService userService = new UserServiceImpl();
 
    /**
     * 提供用户信息返回权限信息
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        String username = (String) principals.getPrimaryPrincipal();
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        // 根据用户名查询当前用户拥有的角色
        Set<Role> roles = userService.findRoles(username);
        Set<String> roleNames = new HashSet<String>();
        for (Role role : roles) {
            roleNames.add(role.getRole());
        }
        // 将角色名称提供给info
        authorizationInfo.setRoles(roleNames);
        // 根据用户名查询当前用户权限
        Set<Permission> permissions = userService.findPermissions(username);
        Set<String> permissionNames = new HashSet<String>();
        for (Permission permission : permissions) {
            permissionNames.add(permission.getPermission());
        }
        // 将权限名称提供给info
        authorizationInfo.setStringPermissions(permissionNames);
 
        return authorizationInfo;
    }
 
    /**
     * 提供账户信息返回认证信息
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        String username = (String) token.getPrincipal();
        User user = userService.findByUsername(username);
        if (user == null) {
            // 用户名不存在抛出异常
            throw new UnknownAccountException();
        }
        if (user.getLocked() == 0) {
            // 用户被管理员锁定抛出异常
            throw new LockedAccountException();
        }
        SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(user.getUsername(),
                user.getPassword(), ByteSource.Util.bytes(user.getCredentialsSalt()), getName());
        return authenticationInfo;
    }
}
