Shiro 安全管理器注入领域和缓存管理器为领域注入各种工具

概要

Realm是工兵角色，需要SecurityManager、CacheManager、Authenticator、Authorizer等

CachingSecurityManager的注入之后

public void setCacheManager(CacheManager cacheManager) {
    this.cacheManager = cacheManager;
    afterCacheManagerSet();
}

protected void afterCacheManagerSet() {
    applyEventBusToCacheManager();
}

RealmSecurityManager的注入之后

public void setRealms(Collection<Realm> realms) {
    if (realms == null) {
        throw new IllegalArgumentException("Realms collection argument cannot be null.");
    }
    if (realms.isEmpty()) {
        throw new IllegalArgumentException("Realms collection argument cannot be empty.");
    }
    this.realms = realms;
    afterRealmsSet();
}

protected void afterRealmsSet() {
    applyCacheManagerToRealms();
    applyEventBusToRealms();
}

protected void applyCacheManagerToRealms() {
    CacheManager cacheManager = getCacheManager();
    Collection<Realm> realms = getRealms();
    if (cacheManager != null && realms != null && !realms.isEmpty()) {
        for (Realm realm : realms) {
            if (realm instanceof CacheManagerAware) {
                ((CacheManagerAware) realm).setCacheManager(cacheManager);
            }
        }
    }
}

AuthenticatingSecurityManager注入之后

protected void afterRealmsSet() {
    super.afterRealmsSet();
    if (this.authenticator instanceof ModularRealmAuthenticator) {
        ((ModularRealmAuthenticator) this.authenticator).setRealms(getRealms());
    }
}

AuthorizingSecurityManager注入之后

protected void afterRealmsSet() {
    super.afterRealmsSet();
    if (this.authorizer instanceof ModularRealmAuthorizer) {
        ((ModularRealmAuthorizer) this.authorizer).setRealms(getRealms());
    }
}
