生而为程序员，真对不起，Redis的队列简单实现

希望在被投新手帖之前能收到一些高手的指责
玩java3年多了，仍然只敢在新手区发帖的人伤不起……
想找自信，就去面试别人，想立志，还是要在eye发帖子

先是Redis的bean定义，@Configuration大赞！xml都见鬼去！

@Configuration
@PropertySource("classpath:mgr.properties")
//@ImportResource("classpath*:spring-config.xml")
public class RedisConf {

    @Value("${redis.url}")
    String redisUrl;

    @Value("${redis.port}")
    String redisPort;

    @Bean
    public JedisPoolConfig jedisPoolConfig(){
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        jedisPoolConfig.setMaxActive(50);
        jedisPoolConfig.setMaxIdle(10);
        jedisPoolConfig.setMaxWait(1000l);
        jedisPoolConfig.setTestOnBorrow(true);
        return jedisPoolConfig;
    }

    @Bean
    public JedisShardInfo jedisShardInfo(){
        return new JedisShardInfo(redisUrl, redisPort);
    }

    @Bean
    public ShardedJedisPool shardedJedisPool(){
        List<JedisShardInfo> jedisList = new ArrayList<JedisShardInfo>();
        jedisList.add(jedisShardInfo());
        return new ShardedJedisPool(jedisPoolConfig(), jedisList);
    }

    @Bean
    public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer(){
        return new PropertySourcesPlaceholderConfigurer();
    }

}

主要的@Configuration

@Configuration
@Import(RedisConf.class)
public class MgrConf {...}

Queue实现

public class JedisQueue<T> {

    private ShardedJedisPool shardedJedisPool;
    private String suffix = "_";
    private String name;
    private Class<T> clazz;

    public JedisQueue(ShardedJedisPool shardedJedisPool, Class<T> clazz) {
        this.shardedJedisPool = shardedJedisPool;
        this.clazz = clazz;
        this.name = clazz.getName();
    }

    public JedisQueue(ShardedJedisPool shardedJedisPool, Class<T> clazz, String suffix) {
        this.shardedJedisPool = shardedJedisPool;
        this.name = clazz.getName();
        this.clazz = clazz;
        this.suffix += suffix;
        this.name += this.suffix;
    }

    public void push(T... ts) {
        ShardedJedis jedis = shardedJedisPool.getResource();
        try {
            for (T t : ts)
                jedis.lpush(name, JsonUtils.toJson(t));
        } finally {
            shardedJedisPool.returnResource(jedis);
        }
    }

    public void push(Collection<T> collection) {
        ShardedJedis jedis = shardedJedisPool.getResource();
        try {
            for (T t : collection)
                jedis.lpush(name, JsonUtils.toJson(t));
        } finally {
            shardedJedisPool.returnResource(jedis);
        }
    }

    public T take() {
        ShardedJedis jedis = shardedJedisPool.getResource();
        try {
            while (true) {
                Threads.sleep(300l);
                if (!jedis.exists(name))
                    continue;
                String jsonT = jedis.rpop(name);
                if (jsonT != null) {
                    return (T) JsonUtils.toT(jsonT, clazz);
                }
            }
        } finally {
            shardedJedisPool.returnResource(jedis);
        }
    }
}

调用Queue

    @Autowired
    public void init(ShardedJedisPool shardedJedisPool){
        proxyQueue = JedisQueue.newQ(shardedJedisPool, Proxy.class);
        tiredQueue = JedisQueue.newQ(shardedJedisPool, Proxy.class, "tired");
    }
