若依下整合多个Redis

提前总结，因此项目已多处使用Redis1 故此我创建的Redis工厂只添加了Redis2并不影响Redis1。但如若还有Redis3、4、5可按照下述方法继续往Redis工厂里添加

下述代码添加到 RedisConfig

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.data.redis.core.BoundSetOperations;
import org.springframework.data.redis.core.HashOperations;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.stereotype.Component;@Value("${custom.redis.host}")private String customRedisHost;@Value("${custom.redis.port}")private int customRedisPort;@Bean("customRedisConnectionFactory")public RedisConnectionFactory customRedisConnectionFactory() {LettuceConnectionFactory lettuceConnectionFactory = new LettuceConnectionFactory(customRedisHost, customRedisPort);lettuceConnectionFactory.setDatabase(1);return lettuceConnectionFactory;}@Bean("customRedisTemplate")public RedisTemplate<Object, Object> customRedisTemplate(RedisConnectionFactory customRedisConnectionFactory) {RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();redisTemplate.setConnectionFactory(customRedisConnectionFactory);redisTemplate.setDefaultSerializer(new StringRedisSerializer()); // 默认使用StringRedisSerializerreturn redisTemplate;}
