SpringBoot中默认提供了StringRedisTemplate，有些场景我们需要存储的不仅仅是String类型，这时我们就需要自己构造一个RedisTemplate。

import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.boot.autoconfigure.data.redis.RedisProperties;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
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.RedisOperations;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@Configuration
@ConditionalOnClass(RedisOperations.class)
@EnableConfigurationProperties(RedisProperties.class)
public class RedisAutoConfiguration {

    /**
     * 构造RedisTemplate<String,Object></String,Object>
     *
     * @param redisConnectionFactory
     * @return
     */
    @Bean
    @ConditionalOnMissingBean(name = "redisTemplate")
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        // 设置连接池
        template.setConnectionFactory(redisConnectionFactory);
        // 设置Key的序列化方式为字符串
        template.setKeySerializer(new StringRedisSerializer());
        // 设置hash结构的key序列化方式为字符串
        template.setHashKeySerializer(new StringRedisSerializer());
        // 设置hash结构的value序列化方式为字符串
        template.setHashValueSerializer(new StringRedisSerializer());
        // 还可以设置很多...
        return template;
    }

    /**
     * StringRedisTemplate默认就有的,可以在这改变下StringRedisTemplate默认的配置
     *
     * @param redisConnectionFactory
     * @return
     */
    @Bean
    @ConditionalOnMissingBean
    public StringRedisTemplate stringRedisTemplate(RedisConnectionFactory redisConnectionFactory) {
        StringRedisTemplate template = new StringRedisTemplate();
        template.setConnectionFactory(redisConnectionFactory);
        return template;
    }
}

使用方式

/**
* 注入自定义的RedisTemplate
* 注意:泛型的类型一定要一致,否则会注入失败
*/
@Autowired
private RedisTemplate<String,Object> redisTemplate;
