Spring+Shiro搭建基于Redis的分布式权限系统（有实例）

摘要: 简单介绍使用Spring+Shiro搭建基于Redis的分布式权限系统。

这篇主要介绍Shiro如何与redis结合搭建分布式权限系统，至于如何使用和配置Shiro就不多说了。完整实例下载地址：https://git.oschina.net/zhmlvft/spring_shiro_redis

要实现分布式，主要需要解决2个大问题。

第一个解决shiro  session共享的问题。这个可以通过自定义sessionDao实现。继承 CachingSessionDao。

public class RedisSessionDao extends CachingSessionDAO {
    private final static Logger log = LoggerFactory.getLogger(RedisSessionDao.class);
</span><span style="color: #0000ff;">private</span> RedisTemplate&lt;String, Object&gt;<span style="color: #000000;"> redisTemplate;
</span><span style="color: #0000ff;">private</span> <span style="color: #0000ff;">int</span> defaultExpireTime = <span style="color: #800080;">3600</span><span style="color: #000000;">;

</span><span style="color: #0000ff;">private</span> CacheManager cm=<span style="color: #0000ff;">null</span><span style="color: #000000;">;

</span><span style="color: #0000ff;">public</span> RedisSessionDao(RedisTemplate&lt;String, Object&gt; redisTemplate,<span style="color: #0000ff;">int</span><span style="color: #000000;"> defaultExpireTime) {
    </span><span style="color: #0000ff;">this</span>.redisTemplate =<span style="color: #000000;"> redisTemplate;
    </span><span style="color: #0000ff;">this</span>.defaultExpireTime =<span style="color: #000000;"> defaultExpireTime;
}

@Override
</span><span style="color: #0000ff;">protected</span><span style="color: #000000;"> Serializable doCreate(Session session) {
    Serializable sessionId </span>=<span style="color: #000000;"> generateSessionId(session);
    cm </span>=<span style="color: #000000;"> CacheManager.create();
    </span><span style="color: #0000ff;">if</span>(cm==<span style="color: #0000ff;">null</span><span style="color: #000000;">){
        cm </span>= <span style="color: #0000ff;">new</span><span style="color: #000000;"> CacheManager(getCacheManagerConfigFileInputStream());
    }
    Ehcache ehCache </span>= cm.getCache(<span style="color: #800000;">"</span><span style="color: #800000;">sessioncache</span><span style="color: #800000;">"</span><span style="color: #000000;">);
    assignSessionId(session, sessionId);
    redisTemplate.opsForValue().</span><span style="color: #0000ff;">set</span><span style="color: #000000;">(sessionId.toString(), session);
    redisTemplate.expire(sessionId.toString(), </span><span style="color: #0000ff;">this</span><span style="color: #000000;">.defaultExpireTime, TimeUnit.SECONDS);
    ehCache.put(</span><span style="color: #0000ff;">new</span><span style="color: #000000;"> Element(sessionId.toString(),session));
    </span><span style="color: #0000ff;">return</span><span style="color: #000000;"> sessionId;
}

@Override
</span><span style="color: #0000ff;">protected</span><span style="color: #000000;"> Session doReadSession(Serializable sessionId) {
    </span><span style="color: #008000;">//</span><span style="color: #008000;">此方法不会执行，不用管</span>
    <span style="color: #0000ff;">return</span> <span style="color: #0000ff;">null</span><span style="color: #000000;">;
}

@Override
</span><span style="color: #0000ff;">protected</span> <span style="color: #0000ff;">void</span><span style="color: #000000;"> doUpdate(Session session) {
    </span><span style="color: #008000;">//</span><span style="color: #008000;">该方法交给父类去执行</span>

    }
@Override
</span><span style="color: #0000ff;">protected</span> <span style="color: #0000ff;">void</span><span style="color: #000000;"> doDelete(Session session) {

    Serializable sessionId </span>=<span style="color: #000000;"> session.getId();
    cm </span>=<span style="color: #000000;"> CacheManager.create();
    </span><span style="color: #0000ff;">if</span>(cm==<span style="color: #0000ff;">null</span><span style="color: #000000;">){
        cm </span>= <span style="color: #0000ff;">new</span><span style="color: #000000;"> CacheManager(getCacheManagerConfigFileInputStream());
    }
    Ehcache ehCache </span>= cm.getCache(<span style="color: #800000;">"</span><span style="color: #800000;">sessioncache</span><span style="color: #800000;">"</span><span style="color: #000000;">);
    redisTemplate.delete(sessionId.toString());
    ehCache.remove(sessionId.toString());
}

</span><span style="color: #0000ff;">protected</span><span style="color: #000000;"> InputStream getCacheManagerConfigFileInputStream() {
    String configFile </span>= <span style="color: #800000;">"</span><span style="color: #800000;">classpath:ehcache.xml</span><span style="color: #800000;">"</span><span style="color: #000000;">;
    </span><span style="color: #0000ff;">try</span><span style="color: #000000;"> {
        </span><span style="color: #0000ff;">return</span><span style="color: #000000;"> ResourceUtils.getInputStreamForPath(configFile);
    } </span><span style="color: #0000ff;">catch</span><span style="color: #000000;"> (IOException e) {
        </span><span style="color: #0000ff;">throw</span> <span style="color: #0000ff;">new</span> ConfigurationException(<span style="color: #800000;">"</span><span style="color: #800000;">Unable to obtain input stream for cacheManagerConfigFile [</span><span style="color: #800000;">"</span> +<span style="color: #000000;">
                configFile </span>+ <span style="color: #800000;">"</span><span style="color: #800000;">]</span><span style="color: #800000;">"</span><span style="color: #000000;">, e);
    }
}</span></pre>

第二个解决shiro cache的问题，这个可以通过自定义CacheManager实现，shiro默认的cache是基于ehcache的，自定义Redis实现的过程可以仿照shiro-ehcache.jar源码来实现。
