redisTemplate.opsForValue().increment的返回值

根据提供的引用内容,redisTemplate.opsForValue().increment()方法的返回值是递增后的值。
以下是一个演示例子:
```java
Long result = redisTemplate.opsForValue().increment("key", 1);
System.out.println("递增后的值为:" + result);
```
该示例中,我们使用redisTemplate的opsForValue()方法获取到一个ValueOperations对象,然后调用increment()方法对指定的key进行递增操作,递增的步长为1。最后,我们打印出递增后的值。

redisTemplate.opsForValue().increment
这是 Redis 的一个操作,用于对某个 key 的值进行原子性的自增操作。其中 `redisTemplate` 是 Redis 的客户端,`opsForValue()` 方法返回一个操作字符串类型的值的对象,`increment()` 方法对指定的 key 进行自增操作。如果该 key 不存在,则会先创建并将值设为 0,再进行自增操作,并返回自增后的值。该方法还可以传入一个自增的步长参数。
redisTemplate.opsForValue().increment()
This Redis command is used to increment the value of a key by a specified amount. The `redisTemplate.opsForValue()` method returns an instance of `ValueOperations`, which provides various operations for working with Redis string values.
The `increment()` method of `ValueOperations` takes two parameters: the key of the Redis string value to increment, and the amount by which to increment the value. If the key does not exist, it is created with an initial value of zero before being incremented.
Example usage:
```
redisTemplate.opsForValue().increment("mykey", 2);
```
This would increment the value of the "mykey" key in Redis by 2. If "mykey" did not exist before, it would be created with a value of 2.
