农村电商平台发展现状优化设计三年级上册语文答案

其实这是在解决一个项目问题是发现的，因为原开发者的大意，造成了系统出现严重的逻辑问题。

因为系统系统采用分模块开发，某模块使用Spring提供的RedisTemplate进行值的读写，另一位使用了框架基于Jedis的一套公用方法进行值的读写，出现的问题就是写入的值，后面读取不到进而进行了无值判断逻辑。

那么是读取不到吗，我使用RDM客户端查看，发现出现了一堆键值都是乱码的内容

然后在代码中加入以下代码:

package com.example.springboot.config;
import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
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
public class RedisConfig {@Beanpublic RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory) {RedisTemplate redisTemplate = new RedisTemplate();redisTemplate.setConnectionFactory(redisConnectionFactory);Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);ObjectMapper objectMapper = new ObjectMapper();objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);jackson2JsonRedisSerializer.setObjectMapper(objectMapper);//重点在这四行代码redisTemplate.setKeySerializer(new StringRedisSerializer());redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);redisTemplate.setHashKeySerializer(new StringRedisSerializer());redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);redisTemplate.afterPropertiesSet();return redisTemplate;}
}

再存入redis就对了
