Spring Boot Redis如何将实体存储键的分隔符从:改为.？

Hey there! I've got you covered on this. When using Spring Data Redis with @RedisHash, the default key separator is a colon, but we can easily switch it to a dot either globally or for a specific entity. Here are two straightforward approaches:

1. Global Configuration (All Entities) #

If you want every entity annotated with @RedisHash to use a dot as the separator, just add this line to your configuration file:

For application.properties #

spring.data.redis.keyspace-separator=.

For application.yml #

spring:
  data:
    redis:
      keyspace-separator: "."

That's it! Now all your Redis keys will use a dot instead of a colon. For your Product entity, saving an instance with id 0 will create the key product.0.

2. Entity-Specific Configuration (Only for Product) #

If you only want the Product entity to use the dot separator (leaving others with the default colon), create a custom configuration class:

import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.core.mapping.KeyspaceConfiguration;
import org.springframework.data.redis.core.mapping.KeyspaceSettings;

import java.util.List;

@Configuration
public class ProductRedisKeyConfig extends KeyspaceConfiguration {

    @Override
    protected Iterable<KeyspaceSettings> initialConfiguration() {
        // Configure settings specifically for the Product class
        KeyspaceSettings productKeySettings = new KeyspaceSettings(Product.class, "product");
        productKeySettings.setSeparator(".");
        
        return List.of(productKeySettings);
    }
}

This configuration tells Spring Data Redis to use a dot as the separator only for the Product entity, while other entities will keep using the colon.

Verify the Result #

After applying either of these changes, when you call dao.save(product) with product.setId("0"), you'll find the key product.0 in your Redis database instead of product:0.
