3、SpringBoot整合Redis

3.1、自動配置類，RedisAutoConfiguration

@Configuration(proxyBeanMethods = false)
@ConditionalOnClass(RedisOperations.class)
@EnableConfigurationProperties(RedisProperties.class)
@Import({ LettuceConnectionConfiguration.class, JedisConnectionConfiguration.class })
public class RedisAutoConfiguration {
 
​
    @Bean
    @ConditionalOnMissingBean(name = "redisTemplate")
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory)
            throws UnknownHostException {
        RedisTemplate<Object, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);
 
        return template;
    }
​
    @Bean
    @ConditionalOnMissingBean
    public StringRedisTemplate stringRedisTemplate(RedisConnectionFactory redisConnectionFactory)
            throws UnknownHostException {
        StringRedisTemplate template = new StringRedisTemplate();
        template.setConnectionFactory(redisConnectionFactory);
 
        return template;
    }
​
}

3.2、自動配置檔案，RedisProperties

@ConfigurationProperties(prefix = "spring.redis")
public class RedisProperties {
​
    /**
     * 連線Redis通常使用0號資料庫
     */
    private int database = 0;
​
    private String url;
​
    private String host = "localhost";
​
    private String password;
​
    private int port = 6379;
​
    //安全連線
    private boolean ssl;
    
  //連線超時
    private Duration timeout;
​
    private String clientName;
​
    private Sentinel sentinel;
​
    private Cluster cluster;
​
    private final Jedis jedis = new Jedis();
​
    private final Lettuce lettuce = new Lettuce();
​
  //......
    
}

3.3、匯入依賴

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

3.4、配置連線

spring:
  redis:
   host: 127.0.0.1
   port: 6379

3.5、測試

@Test
public void test(){
  redisTemplate.opsForValue().set("key","value");
  System.out.println(redisTemplate.opsForValue().get("key"));
}
