Springboot整合Redis，Json序列化

重写RedisConfig

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;

import java.net.UnknownHostException;

@Configuration
public class RedisConfig {
    
    

    @Bean
    @SuppressWarnings("all")
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) throws UnknownHostException {
    
    
        RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
        template.setConnectionFactory(redisConnectionFactory);

        // json序列化配置
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);

        // String 的序列化
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();

        // key采用String的序列化方式
        template.setKeySerializer(stringRedisSerializer);
        template.setHashKeySerializer(stringRedisSerializer); // hash
        template.setValueSerializer(jackson2JsonRedisSerializer); // value
        template.setHashValueSerializer(jackson2JsonRedisSerializer); // hash的value
        template.afterPropertiesSet();

        return template;
    }


}

简单的pojo

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.stereotype.Component;

import java.io.Serializable;

@Component
@AllArgsConstructor
@NoArgsConstructor
@Data
public class User implements Serializable {
    
     // 几乎所有的pojo类都会序列化

    private String name;

    private int age;

}

测试类

import com.fasterxml.jackson.core.JsonProcessingException;
import com.jyuxuan.redis.pojo.User;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.RedisTemplate;

@SpringBootTest
class RedisClassApplicationTests {
    
    

    @Autowired
    @Qualifier("redisTemplate")
    private RedisTemplate redisTemplate;
    

    @Test
    public void test() throws JsonProcessingException {
    
    
        // 使用json传递对象
        User user = new User("学习不易",20);
        redisTemplate.opsForValue().set("user",user);
        System.out.println(redisTemplate.opsForValue().get("user"));
    }

}
