shiro的源码学习（四）深入理解realm

1 public interface Realm {
2      String getName();//返回Realm的名字，唯一
3      boolean supports(AuthenticationToken token);//校验token
4      AuthenticationInfo getAuthenticationInfo(AuthenticationToken token) throws AuthenticationException;//返回用户信息
5 }

 1 public abstract class CachingRealm implements Realm, Nameable, CacheManagerAware, LogoutAware {
 2     private String name;
 3     private boolean cachingEnabled;//支持缓存，默认为true
 4     private CacheManager cacheManager; //注入缓存器
 5     public CachingRealm() {
 6         this.cachingEnabled = true;
 7         this.name = getClass().getName() + "_" + INSTANCE_COUNT.getAndIncrement();
 8     }

11         this.cacheManager = cacheManager;
12         afterCacheManagerSet();
13     }
14     public void onLogout(PrincipalCollection principals) {
15         clearCache(principals);
