【Spring Boot】访问操作redis

一、连接操作redis

Spring Boot中操作redis还是需要使用相关的启动器

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

按照之前的逻辑 我们还是要分析一下这个启动器的自动配置类RedisAutoConfiguration做了什么

@AutoConfiguration
@ConditionalOnClass({
   
   RedisOperations.class})
// 将spring.redis开头的配置和redis进行绑定
@EnableConfigurationProperties({
   
   RedisProperties.class})
// 引入了两个redis连接客户端，Lettuce（启动器默认使用）和Jedis的连接配置类
@Import({
   
   LettuceConnectionConfiguration.class, JedisConnectionConfiguration.class})
public class RedisAutoConfiguration {
   
   
    public RedisAutoConfiguration() {
   
   
    }

	// 注入redisTemplate类，认定key-value都是Object类型
    @Bean
    @ConditionalOnMissingBean(
        name = {
   
   "redisTemplate"}
    )
    @ConditionalOnSingleCandidate(RedisConnectionFactory.class)
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
   
   
        RedisTemplate<Object, Object> template = new RedisTemplate();
        template.setConnectionFactory(redisConnectionFactory);
        return template;
    }

	// 注入St
