SpringBoot集成Redis的方法及步骤

搭建环境，开启Redis服务

1.首先导入依赖

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

2.在application.yml中进行配置，配置如下，密码根据需求无密码可省略

redis:
  host: 127.0.0.1
  port: 6379
  database: 0
  #password: 123456

3.redis序列化器（可选)

主要是对 redis键值对进行序列化：一般只序列化键

import org.springframework.cache.annotation.CachingConfigurerSupport;
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.StringRedisSerializer;
​
@Configuration
public class RedisConfig extends CachingConfigurerSupport {
​
    @Bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory connectionFactory) {
        RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
​
        //默认的Key序列化器为：JdkSerializationRedisSerializer
        redisTemplate.setKeySerializer(new StringRedisSerializer()); // key序列化
        //redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer()); // value序列化
​
        redisTemplate.setConnectionFactory(connectionFactory);
        return redisTemplate;
    }
}

4.在Controller中注入RedisTemplate即可

  @Autowired
    private RedisTemplate redisTemplate;

接下来就可以通过redisTemplate进行操作了。
