解决redisTemplate向redis中插入String类型数据时出现乱码问题

redisTemplate.opsForValue().set("name","谷歌");

@SpringBootTest
class SpringDataRedisDemoApplicationTests {
 
    @Resource
    private RedisTemplate redisTemplate;
 
    @Test
    void testString() {
        // 写入String数据
        redisTemplate.opsForValue().set("name","谷歌");
    }
 
}

public class RedisTemplate<K, V> extends RedisAccessor implements RedisOperations<K, V>, BeanClassLoaderAware {
 
	@Override
	public void afterPropertiesSet() {
        ...
		if (defaultSerializer == null) {
 
			defaultSerializer = new JdkSerializationRedisSerializer(
					classLoader != null ? classLoader : this.getClass().getClassLoader());
		}
        ...
    }
}
   

public class RedisTemplate<K, V> extends RedisAccessor implements RedisOperations<K, V>, BeanClassLoaderAware {
 
	private @Nullable RedisSerializer<?> defaultSerializer;
	private @Nullable RedisSerializer keySerializer = null;
	private @Nullable RedisSerializer valueSerializer = null;
	private @Nullable RedisSerializer hashKeySerializer = null;
	private @Nullable RedisSerializer hashValueSerializer = null;
}

@Configuration
public class RedisConfig {
 
    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory connectionFactory){
        //创建RedisTemplate对象
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        //设置连接工厂
        template.setConnectionFactory(connectionFactory);
        //创建JSON序列化工具
        GenericJackson2JsonRedisSerializer jsonRedisSerializer = new GenericJackson2JsonRedisSerializer();
        //设置key的序列化
        template.setKeySerializer(RedisSerializer.string());
        template.setHashKeySerializer(RedisSerializer.string());
        //设置value的序列化
        template.setValueSerializer(jsonRedisSerializer);
        template.setHashKeySerializer(jsonRedisSerializer);
        //返回
        return template;
    }
}

@SpringBootTest
class SpringDataRedisDemoApplicationTests {
 
    @Autowired
    private RedisTemplate<String,Object> redisTemplate;
 
 
    @Test
    void testString() {
        // 写入String数据
        redisTemplate.opsForValue().set("name","百度");
        // 获取String数据
        Object name = redisTemplate.opsForValue().get("name");
        System.out.println(name);
    }
 
}
