#Redis #Springboot集成redis

本文介绍了如何在SpringBoot项目中集成Redis，包括在application.properties中配置Redis连接信息，使用RedisConfig.java设置FastJson序列化，以及创建RedisTool工具类进行数据存取操作。通过这些步骤，可以方便地在应用中调用Redis存储和检索数据。

1.application.properties

配置redis连接信息

#Redis数据库连接配置
spring.redis.host=122.115.36.168
spring.redis.port=6379
spring.redis.password=DEVElopQSX@$^123
spring.redis.timeout=1000

2.RedisConfig.java

配置Redis序列化，这里使用的是FastJson

package com.robot.config;

import com.alibaba.fastjson.support.spring.FastJsonRedisSerializer;
import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.CachingConfigurerSupport;
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.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.StringRedisSerializer;

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

@EnableCaching
@Configuration
public class RedisConfig extends CachingConfigurerSupport {

    @Bean(name="redisTemplate")
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<Object, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);

        FastJsonRedisSerializer<Object> serializer = new FastJsonRedisSerializer<Object>(Object.class);
        // value值的序列化采用fastJsonRedisSerializer
        template.setValueSerializer(serializer);
        template.setHashValueSerializer(serializer);
        // key的序列化采用StringRedisSerializer
        template.setKeySerializer(new StringRedisSerializer());
        template.setHashKeySerializer(new StringRedisSerializer());

        template.setConnectionFactory(redisConnectionFactory);
        return template;
    }

    @Bean
    public CacheManager cacheManager(RedisConnectionFactory factory) {
        // 生成一个默认配置，通过config对象即可对缓存进行自定义配置
        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig();
        // 设置缓存的默认过期时间，也是使用Duration设置
        config = config.entryTtl(Duration.ofMinutes(1))
                .disableCachingNullValues();     // 不缓存空值

        // 设置一个初始化的缓存空间set集合
        Set<String> cacheNames =  new HashSet<>();
        cacheNames.add("my-redis-cache1");
        cacheNames.add("my-redis-cache2");

        // 对每个缓存空间应用不同的配置
        Map<String, RedisCacheConfiguration> configMap = new HashMap<>();
        configMap.put("my-redis-cache1", config);
        configMap.put("my-redis-cache2", config.entryTtl(Duration.ofSeconds(120)));

        // 使用自定义的缓存配置初始化一个cacheManager
        RedisCacheManager cacheManager = RedisCacheManager.builder(factory)
                .initialCacheNames(cacheNames)  // 注意这两句的调用顺序，一定要先调用该方法设置初始化的缓存名，再初始化相关的配置
                .withInitialCacheConfigurations(configMap)
                .build();
        return cacheManager;
    }
}
