springboot使用redis缓存乱码（key或者 value 乱码）一招解决

如果查看redis中的值是这样

创建一个配置类就可以解决

package com.deka.config;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.script.DefaultRedisScript;
import org.springframework.data.redis.core.script.RedisScript;
import org.springframework.data.redis.listener.RedisMessageListenerContainer;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
import org.springframework.scripting.support.ResourceScriptSource;@Configuration
public class RedisConfig {@Autowiredprivate RedisConnectionFactory redisConnectionFactory;@Autowiredprivate RedisTemplate redisTemplate;@Beanpublic RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory factory) {redisTemplate.setConnectionFactory(factory);Jackson2JsonRedisSerializer<Object> serializer = new Jackson2JsonRedisSerializer<Object>(Object.class);redisTemplate.setDefaultSerializer(serializer);//设置序列化Key的实例化对象redisTemplate.setKeySerializer(new StringRedisSerializer());//设置序列化Value的实例化对象redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());return redisTemplate;}@Beanpublic RedisMessageListenerContainer redisContainer() {final RedisMessageListenerContainer container = new RedisMessageListenerContainer();container.setConnectionFactory(redisConnectionFactory);return container;}@Beanpublic RedisScript<Long> limitRedisScript() {DefaultRedisScript<Long> redisScript = new DefaultRedisScript<>();redisScript.setScriptSource(new ResourceScriptSource(new ClassPathResource("scripts/limit.lua")));redisScript.setResultType(Long.class);return redisScript;}}
