注：接收不需要连接池，而发送需要连接池，是因为，接收在启动项目时就要注册监听，数目是固定的，而发送则会随着时间数目不断在变动，需要连接池，性能更优。

重点代码：

private static void initMQObjectPool() {

　　

private static Map<String, GenericObjectPool<MQObject>> mqObjectPool = new ConcurrentHashMap<String, GenericObjectPool<MQObject>>(100);

MQObjectFactory factory = new ActiveMQObjectFactory(bean.getBrokerId());

GenericObjectPoolConfig config = new GenericObjectPoolConfig();

config.setMaxTotal(MaxTotal());

config.setBlockWhenExhausted(BlockWhenExhausted());

config.setMaxWaitMillis(MaxWaitMillis());

config.setNumTestsPerEvictionRun(NumTestsPerEvictionRun());

config.setTestOnBorrow(TestOnBorrow());

config.setTestOnReturn(TestOnReturn());

config.setTestWhileIdle(TestWhileIdle());

config.setTimeBetweenEvictionRunsMillis(TimeBetweenEvictionRunsMillis());

config.setMinEvictableIdleTimeMillis(MinEvictableIdleTimeMillis());

GenericObjectPool<MQObject> pool = new GenericObjectPool<MQObject>(factory, config);

mqObjectPool.put(bean.getBrokerId(), pool);

}

}
