Как правильно реализовать ehcache для apache shiro в весенней загрузке и совместную работу с ehcache для весенней загрузки?

Я использую Apache Shiro 1.4.0 в Spring Boot 2.1.0 для управления безопасностью.И в Широ, и в весне мне нужно использовать ehCache.

Для Широ я хочу использовать функцию блокировки учетной записи при вводе ошибок при вводе пароля.

У меня есть класс CacheConfig для интеграции менеджера кэша;
Затем я интегрировалCacheManager в ShiroConfig;
Затем я реализую RetryLimitHashedCredentialsMatcher;
Наконец, запустить приложение, запуск Spring Boot не удался.

ссылки в POM.XML

<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-ehcache</artifactId>
    <version>1.4.0</version>
</dependency>``

Класс CacheConfig 

@Configuration
public class CacheConfig  {
    @Bean(name = "ehCache")
    public EhCacheManagerFactoryBean ehCacheManagerFactoryBean() {
        EhCacheManagerFactoryBean cacheBean = new EhCacheManagerFactoryBean();
        cacheBean.setConfigLocation(new ClassPathResource("configs/ehcache/ehcache.xml"));
        cacheBean.setShared(false);
        return cacheBean;
    }

    @Bean("springCacheManager")
    public EhCacheCacheManager ehCacheCacheManager(@Qualifier("ehCache") CacheManager ehcacheManager) {
        EhCacheCacheManager ehCacheCacheManager = new EhCacheCacheManager(ehcacheManager);
        return ehCacheCacheManager;
    }

    @Bean("shiroCacheManager")
    public EhCacheManager ehCacheManager() {
        EhCacheManager ehCacheManager = new EhCacheManager();  
ehCacheManager.setCacheManager(ehCacheManagerFactoryBean().getObject());
            return ehCacheManager;
        }
    }

Класс ShiroConfig, связанный со ссылкой ehCache 

@Configuration
public class ShiroConfig {  
    ...  

    @Bean(name = "securityManager")
    public SecurityManager securityManager(@Qualifier("rptShiroRealm")RptShiroRealm rptShiroRealm, EhCacheManager ehCacheManager) {
        DefaultWebSecurityManager defaultWebSecurityManager = new DefaultWebSecurityManager();
        // Setting Realm
        defaultWebSecurityManager.setRealm(rptShiroRealm);
        // Set Shiro to use Cache
        defaultWebSecurityManager.setCacheManager(ehCacheManager);

        return defaultWebSecurityManager;
    }

    @Bean
    public EhCacheManager ehCacheManager(CacheManager shiroCacheManager) {
        EhCacheManager em = new EhCacheManager();
        // Convert ehCacheManager to Shiro wrapped ehCacheManager object,
        // this make spring to manage cache
        em.setCacheManager(shiroCacheManager);
        return em;
    }

    ...
}

Custome RptShiroRealm class 

@Component(value = "rptShiroRealm")
public class RptShiroRealm extends AuthorizingRealm {
    ...
    @PostConstruct
    public void initCredentialsMatcher() {
        RetryLimitHashedCredentialsMatcher matcher = new RetryLimitHashedCredentialsMatcher();

        matcher.setHashAlgorithmName(ShiroConstant.HASH_ALGORITHM);
        matcher.setHashIterations(ShiroConstant.HASH_INTERATIONS);
        matcher.setStoredCredentialsHexEncoded(
            ShiroConstant.STORED_CREDENTIALS_HEX_ENCODED); 
        setCredentialsMatcher(matcher);
    } 
    ...
}

Последний класс RetryLimitHashedCredentialsMatcher 

public class RetryLimitHashedCredentialsMatcher extends HashedCredentialsMatcher {
    @Autowired
    private CacheManager shiroCacheManager;
    private Ehcache passwordRetryCache;

    public RetryLimitHashedCredentialsMatcher() {
        passwordRetryCache = shiroCacheManager.getCache("passwordRetryCache");
}

    @Override
    public boolean doCredentialsMatch(AuthenticationToken token, AuthenticationInfo info) {
        String username = (String)token.getPrincipal();
        //retry count + 1
        Element element = passwordRetryCache.get(username);
        if(element == null) {
            element = new Element(username , new AtomicInteger(0));
            passwordRetryCache.put(element);
        }
        AtomicInteger retryCount = (AtomicInteger)element.getObjectValue();
        if(retryCount.incrementAndGet() > 5) {
            //if retry count > 5 throw
            throw new ExcessiveAttemptsException();
        }

        boolean matches = super.doCredentialsMatch(token, info);
        if(matches) {
            //clear retry count
            passwordRetryCache.remove(username);
        }
        return matches;
    }
}

Когда я запускаю приложение, оно вызывает исключение стека, как показано ниже:

Как я могу починить NPE ... Я не знаю, почему он вынимается ... Может ли кто-нибудь помочь мне исправить это, Большое спасибо?
Я нашел сутьиз которых причины исключения есть в моем пользовательском ShrioRealm, где я ссылаюсь на RetryLimitHashedCredentialsMatcher, я не могу его использовать.

На первый взгляд кажется, что вам нужно внедрить RetryLimitHashedCredentialsMatcher вместо управления объектом вне Spring, поскольку вы автоматически подключаете объекты внутри него.
