zf2 redis 練手2

1. 接着上文，不可能每次都都去實例化redis，這很麻煩，並且redis的配置沒有分離，這樣耦合度很高，不利於後續的代碼修改，因此有修改了。

2. 首先仍是要啓動redis-server，

3. 在global.php

   
   

4.   return array(
        'redis_config'=>array(
       	'Server'	=>'127.0.0.1:6379',
       	'Database' 	=>'0',
       	'Namespace'	=>'session',
       	'Writable'	=>true,
           'Readable'	=>true,
           ),
   
       'service_manager' => array(
   	        'factories' => array(
   	            'Zend\Db\Adapter\Adapter\Redis' => function ($sm) {
   	            	$config = $sm->get('Configuration');
   	            	if(isset($config['redis_config'])){
   	            		//redis option
   	            	$config_redis = $config['redis_config'];
   	            	$redisOption = new \Zend\Cache\Storage\Adapter\RedisOptions();
   	            	$redisOption->setServer($config_redis['Server'])
   	            		->setDatabase($config_redis['Database'])
   	            		->setNamespace($config_redis['Namespace'])
   	            		->setWritable($config_redis['Writable'])
   	            		->setReadable($config_redis['Readable']);
   	            		return new \Zend\Cache\Storage\Adapter\Redis($redisOption)
   	            	}
   	            },
   	        ),
   	    ),
   );

   以後在調用的地方

5.  public function redisAction()
       {
       	//獲取redis
       	$redis = $this->getServiceLocator()->get('Zend\Db\Adapter\Adapter\Redis');
       	$redis->setItem('zzc', 'zhangzhican110@gmail.com');
       	die;
       }
