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
cpp 复制代码
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 {

    @Autowired
    private RedisConnectionFactory redisConnectionFactory;

    @Autowired
    private RedisTemplate redisTemplate;

    @Bean
    public 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;
    }

    @Bean
    public RedisMessageListenerContainer redisContainer() {
        final RedisMessageListenerContainer container = new RedisMessageListenerContainer();
        container.setConnectionFactory(redisConnectionFactory);
        return container;
    }

    @Bean
    public RedisScript<Long> limitRedisScript() {
        DefaultRedisScript<Long> redisScript = new DefaultRedisScript<>();
        redisScript.setScriptSource(new ResourceScriptSource(new ClassPathResource("scripts/limit.lua")));
        redisScript.setResultType(Long.class);
        return redisScript;
    }

}
