SPringBoot集成Redis

Redis搭建:

1.添加redis依赖

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
 </dependency>

2. 配置连接 redis
在application.yml文件中添加Redis的配置信息:

3.测试
在springboot自带的text中测试:
1… 注入 Redistemplate

2.测试代码

4.注意
Java在redis存储的内容在Redis中会乱码,因此我们要写一个配置文件防止乱码.

import org.springframework.data.redis.core.Redistemplate;

@Configuration
public class RedisConfig {

    /**

    @Bean
    public Redistemplate<String, Object> redistemplate(RedisConnectionFactory connectionFactory) {
        Redistemplate<String, Object> redistemplate = new Redistemplate<>();
        redistemplate.setConnectionFactory(connectionFactory);
        Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<Object>(Object.class);
        StringRedisSerializer redisSerializer = new StringRedisSerializer();
        redistemplate.setKeySerializer(redisSerializer);
        redistemplate.setHashKeySerializer(redisSerializer);
        redistemplate.setValueSerializer(jackson2JsonRedisSerializer);
        redistemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
        return redistemplate;
    }
}
