springboot 整合 redis 简单示例 （可设置缓存过期）

package com.example.demo.pojo; import com.fasterxml.jackson.annotation.JsonAutoDetect; import com.fasterxml.jackson.annotation.PropertyAccessor; import com.fasterxml.jackson.databind.ObjectMapper; import org.springframework.boot.autoconfigure.cache.CacheManagerCustomizer; import org.springframework.cache.annotation.EnableCaching; import org.springframework.cache.ehcache.EhCacheCacheManager; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.data.redis.cache.RedisCacheManager; import org.springframework.data.redis.connection.RedisConnectionFactory; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer; import org.springframework.data.redis.serializer.StringRedisSerializer; @Configuration @EnableCaching public class CacheManagerCustomizerInitializer { @Bean public CacheManagerCustomizer<EhCacheCacheManager> ehcacheManagerCustomizer() { return cacheManager -> { //自定义设置 System.out.println("ehcache cacheManager customizer."); }; } @Bean public CacheManagerCustomizer<RedisCacheManager> redisManagerCustomizer() { return cacheManager -> { System.out.println("redis cacheManager customizer."); }; } // 自己定义一个 RedisTemplate,改变默认的jdk序列化方式，转为json，方便之后进行key的删除，并取消警告信息 @Bean @SuppressWarnings("all") public RedisTemplate redisTemplate(RedisConnectionFactory factory) { RedisTemplate template = new RedisTemplate(); template.setConnectionFactory(factory); // Json序列化配置 Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class); ObjectMapper om = new ObjectMapper(); om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY); om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL); jackson2JsonRedisSerializer.setObjectMapper(om); // String 的序列化 StringRedisSerializer stringRedisSerializer = new StringRedisSerializer(); // key采用String的序列化方式 template.setKeySerializer(stringRedisSerializer); // hash的key也采用String的序列化方式 template.setHashKeySerializer(stringRedisSerializer); // value序列化方式采用jackson template.setValueSerializer(jackson2JsonRedisSerializer); // hash的value序列化方式采用jackson template.setHashValueSerializer(jackson2JsonRedisSerializer); template.afterPropertiesSet(); return template; } }
