Spring boot 整合shiro

1：引入shiro依赖

<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring-boot-web-starter</artifactId>
    <version>1.6.0</version>
</dependency>

2.编写realm的规范，也就是授权与认证的规则

public class UserRealm extends AuthorizingRealm {
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("授权");
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();

        Subject subject = SecurityUtils.getSubject();
        User user= (User) subject.getPrincipal();//拿到认证时候 存储的user对象

        info.addStringPermission(user.getPerms());//把用户的实际权限放入
        return info;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        System.out.println("认证");

        UsernamePasswordToken usernamePasswordToken= (UsernamePasswordToken) authenticationToken;

        User user=userService.queryUserByName(usernamePasswordToken.getUsername());
        if (user==null){//数据库里没有这个人
            return  null;
        }
        return new SimpleAuthenticationInfo(user,user.getPwd(),"");//使用简单的认证传递过去，可以使用其他的MD5,与MD5颜值加密
    }
}

3：编写shiro的config文件

@Configuration
public class ShiroConfig {

    @Bean(name = "shiroFilterFactoryBean")
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("bean") DefaultWebSecurityManager manager){
        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
        //设置安全管理器
        bean.setSecurityManager(manager);

        Map<String, String> map = new LinkedHashMap<>();
        map.put("user/add","user:add");//这里就是 用户权限字段里的值 ,从UserRealme中拿
        map.put("user/update","uers:update");
        bean.setFilterChainDefinitionMap(map);
        return bean;

    }

    //安全管理器
    @Bean(name = "bean")
    public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
        DefaultWebSecurityManager defaultWebSecurityManager=new DefaultWebSecurityManager();

        defaultWebSecurityManager.setRealm(userRealm);
        return defaultWebSecurityManager;
    }

    @Bean
    public UserRealm userRealm(){
        return new UserRealm();
    }
}

这是错误
