RedisTemplate序列化机制存储的自定义更改

SpringBoot环境下的操作，记得导入Redis起步依赖

改变前：

存储的数据是序列化后的结果

改变后：

存储的是json字符串

步骤：
1.写一个自定义配置类
注意：需要修改泛型，把第二个参数User改成你要json序列化存储的bean类

package com.xuexi.cache.config;
import com.xuexi.cache.bean.User;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
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 java.net.UnknownHostException;

@Configuration
public class RedisConfig {
    
    

    @Bean
    @ConditionalOnMissingBean(name="redisTemplate")
    //需要修改泛型，把第二个参数User改成你要json序列化存储的bean类
    public RedisTemplate<Object, User> UserRedisTemplate(
            RedisConnectionFactory redisConnectionFactory)
            throws UnknownHostException{
    
    
        RedisTemplate<Object,User> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);
        Jackson2JsonRedisSerializer<User> ser = new Jackson2JsonRedisSerializer<User>(User.class);
        template.setDefaultSerializer(ser);
        return template;
    }
}

2.使用自定义的UserRedisTemplate
注意：属性名和上面配置类的方法名一致
例：

@Autowired
RedisTemplate<Object,User> UserRedisTemplate;



    @Override
    public void test01() {
    
    
        UserRedisTemplate.opsForValue().set("a",new User("zhangsan","s","s"));
    }
