Jedis 客户端实现

Jedis 简单使用

使用commons-pool连接池

- */
- private static JedisPoolConfig initPoolConfig() {
- JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
- // 控制一个pool最多有多少个状态为idle的jedis实例
- jedisPoolConfig.setMaxActive(1000);
- // 最大能够保持空闲状态的对象数
- jedisPoolConfig.setMaxIdle(300);
- // 超时时间
- jedisPoolConfig.setMaxWait(1000);
- // 在borrow一个jedis实例时,是否提前进行alidate操作;如果为true,则得到的jedis实例均是可用的;
- jedisPoolConfig.setTestOnBorrow(true);
- // 在还会给pool时,是否提前进行validate操作
- jedisPoolConfig.setTestOnReturn(true);
- return jedisPoolConfig;
- }
- /**
- * 初始化jedis连接池
- * <br>------------------------------<br>
- */
- @BeforeClass
- public static void before() {
- JedisPoolConfig jedisPoolConfig = initPoolConfig();
- // 属性文件读取参数信息
- ResourceBundle bundle = ResourceBundle.getBundle("redis_config");
- String host = bundle.getString("redis.host");
- int port = Integer.valueOf(bundle.getString("redis.port"));

- String password = bundle.getString("redis.password");
- // 构造连接池
- jedisPool = new JedisPool(jedisPoolConfig, host, port, timeout, password);
- }
- @Test
- public void testSet() {
- Jedis jedis = null;
- // 从池中获取一个jedis实例
- try {
- jedis = jedisPool.getResource();
- jedis.set("blog_pool", "java2000_wl");
- } catch (Exception e) {
- // 销毁对象
- jedisPool.returnBrokenResource(jedis);
- Assert.fail(e.getMessage());
- } finally {
- // 还会到连接池
- jedisPool.returnResource(jedis);
- }
- }
- @Test
- public void testGet() {
- Jedis jedis = null;
- try {
- // 从池中获取一个jedis实例
- jedis = jedisPool.getResource();
- System.out.println(jedis.get("blog_pool"));
- } catch (Exception e) {

- jedisPool.returnBrokenResource(jedis);
- Assert.fail(e.getMessage());
- } finally {
- // 还会到连接池
- jedisPool.returnResource(jedis);
- }
- }
- }
切记: 当出现异常时 要销毁对象 returnBrokenResource, 使用完之后要 还会连接returnResource
