Redistemplate common collection instructions opsforzset (VI)

The basic configuration has been introduced in the previous 《RedisTemplate Instructions for common sets ( One )]》 Has been introduced in , Now let's introduce it directly opsForZSet() Use of methods ：

1、add(K key, V value, double score)

Add the element to the variable and specify the score of the element .

redisTemplate.opsForZSet().add("zSetValue","A",1);
redisTemplate.opsForZSet().add("zSetValue","B",3);

redisTemplate.opsForZSet().add("zSetValue","D",5);

2、range(K key, long start, long end)

​ Get the element of the specified interval of the variable .

​

Set zSetValue = redisTemplate.opsForZSet().range("zSetValue",0,-1);
System.out.println(" adopt range(K key, long start, long end) Method to get the element of the specified interval :" + zSetValue);

3、rangeByLex(K key, RedisZSetCommands.Range range)

Used to obtain information that meets the requirements of non - score Sort value of . This sort can only be used if there are the same scores , If there are different scores, the return value is uncertain .

//range.gt("A");
range.lt("D");
