我尝试在SpringBoot项目中配置redis连接。应用程序启动时没有任何问题，但当我尝试测试任何Redis操作时，特别是当调用实际调用仓库的REST控制器时，我总是遇到相同的错误。
下面是我在pom.xml中使用的版本：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.6.6</version>
    <relativePath />
</parent>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

下面是我用来连接Redis的配置类：

@Configuration
@RequiredArgsConstructor
public class RedisConfigurationBuilder {

    private final RedisProperties redisProperties;

    @Bean
    public RedisConnectionFactory redisConnectionFactory() {
        try {
            RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration();
            redisStandaloneConfiguration.setHostName(redisProperties.getHost());
            redisStandaloneConfiguration.setPort(redisProperties.getPort());
            redisStandaloneConfiguration.setUsername(redisProperties.getUsername());
            redisStandaloneConfiguration.setPassword(RedisPassword.of(redisProperties.getPassword()));

            LettuceClientConfiguration clientConfig = LettuceClientConfiguration.builder().useSsl().and()
                    .commandTimeout(Duration.ofSeconds(2)).build();

            return new LettuceConnectionFactory(redisStandaloneConfiguration, clientConfig);
        } catch (Exception e) {
            throw new RuntimeException("Failed to configure Redis", e);
        }
    }

    @Bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory connectionFactory) {
        RedisTemplate<Object, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(connectionFactory);
        template.setDefaultSerializer(new GenericJackson2JsonRedisSerializer());
        template.setKeySerializer(new StringRedisSerializer());
        template.setHashKeySerializer(new GenericJackson2JsonRedisSerializer());
        template.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        return template;
    }
}

这是RedisProperties类，它从我的application.yml文件中读取属性：

@Component
@Getter
public class RedisProperties {

    @Value("${spring.data.redis.host}")
    private String host;

    @Value("${spring.data.redis.port}")
    private int port;

    @Value("${spring.data.redis.username}")
    private String username;

    @Value("${spring.data.redis.password}")
    private String password;

}

最后，这是我的应用程序。yml：

spring:
  application:
    name: "application-name"
  data:
    redis:
      host: {hostName}
      port: 6379
      username: {myUsername}
      password: {myPassword}
      ssl: 
        enabled: true

注意事项：在堆栈跟踪中，我将真实的主机名替换为{hostName}，只是为了隐藏我连接到的实际服务器。错误消息如下：
org.springframework.data.redis.RedisConnectionFailureException：Unable to connect to Redis; nested exception is io.lettuce.core.RedisConnectionException：Unable to connect to {hostName}：6379/< unresolved >：6379
这是我不断得到的错误的堆栈跟踪：
