Shiro realm配置了还是找不到

Java代码：

public class CurrentIniRealm extends TextConfigurationRealm{
    
        public static final String USERS_SECTION_NAME = "users";
        public static final String ROLES_SECTION_NAME = "roles";

        .............................

@Component
public class UserRealm extends AuthorizingRealm {

    @Autowired
    private UserManager userService;

    public UserRealm() {
        setName("UserRealm");
        setCredentialsMatcher(new HashedCredentialsMatcher("SHA-256"));
    }

...........................

xml代码：

<bean id="iniRealm" class="com.boonya.shiro.security.CurrentIniRealm">

        <constructor-arg type="java.lang.String" value="classpath:shiro.ini" />
        <property name="credentialsMatcher" ref="credentialsMatcher" />
    </bean>
    <bean id="userRealm" class="com.boonya.shiro.security.UserRealm" />
    
    <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
        <property name="realms">
            <list>
                <ref bean="iniRealm" />
                <ref bean="userRealm" />
            </list>
        </property>
        <property name="cacheManager" ref="cacheManager" />

    </bean>

出现的问题：登录的时候总是报找不到任何realm：一直在登录页面

<应该不是URL字符过滤的问题>
