[TOC] # 簡介 redis中hashes類型可以看做具有String key和String value的map容器  # 命令行    # 代碼 ## 存數據 ~~~ @Test public void testHash() { Jedis jedis = init(); jedis.hset("cart:user02","書","高性能mysql"); jedis.hset("cart:user02","筆","圓珠筆"); jedis.hset("cart:user02","畫","八駿圖"); jedis.close(); } ~~~ ## 查詢 ~~~ @Test public void testSelect() { Jedis jedis = init(); Map<String, String> hgetAll = jedis.hgetAll("cart:user02"); Set<Map.Entry<String, String>> entrySet = hgetAll.entrySet(); for (Map.Entry<String, String> entry : entrySet) { System.out.println(entry.getKey() + ":" + entry.getValue()); } } ~~~ ## 自增 ~~~ Jedis jedis = init(); jedis.hset("cart:user", "價格1", "1"); jedis.hset("cart:user", "價格2", "1"); //給價格1的值+1 jedis.hincrBy("cart:user", "價格1", 1); jedis.close(); ~~~ ## 刪除 ~~~ Jedis jedis = init(); jedis.hdel("cart:user", "價格1"); jedis.close(); ~~~
