SpringBoot使用Redis缓存配置(多cachename,不同的ttl)

1.增加maven依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-cache</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

2.增加redis配置（application.yaml)

spring:
  redis:
    database: 0
    host: localhost

3.增加CacheManager配置

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.cache.RedisCacheConfiguration;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.cache.RedisCacheWriter;
import org.springframework.data.redis.core.RedisTemplate;

import java.time.Duration;
import java.util.HashMap;
import java.util.Map;

@EnableCaching
@Configuration
public class CacheConfiguration {
    @Autowired
    private RedisTemplate redisTemplate;

    @Bean
    public RedisCacheWriter writer() {
        return RedisCacheWriter.nonLockingRedisCacheWriter(redisTemplate.getConnectionFactory());
    }

    @Bean
    public CacheManager cacheManager() {
        Map<String, RedisCacheConfiguration> configurationMap = new HashMap<>();
        configurationMap.put("cache1", RedisCacheConfiguration.defaultCacheConfig().entryTtl(Duration.ofDays(1)));
        configurationMap.put("cache2", RedisCacheConfiguration.defaultCacheConfig().entryTtl(Duration.ofDays(2)));

        return RedisCacheManager.builder(writer())
                .initialCacheNames(configurationMap.keySet())
                .withInitialCacheConfigurations(configurationMap)
                .build();
    }
}
