如何解决嵌套异常是 io.lettuce.core.RedisException: java.io.IOException: An existing connection was forceed closed by the remote host
我在 springboot 应用程序中使用了 redis 缓存。突然它开始给出以下异常:
ERROR 1876 --- [http-nio-8004-exec-6] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing Failed; nested exception is org.springframework.data.redis.RedisSystemException: Redis exception; nested exception is io.lettuce.core.RedisException: java.io.IOException: An existing connection was forcibly closed by the remote host] with root cause
java.io.IOException: An existing connection was forcibly closed by the remote host

这是我的redis配置:
@Configuration
public class RedisConfig {
@Autowired
private Environment environment;
@Bean
public LettuceConnectionFactory redisConnectionFactory(){
return new LettuceConnectionFactory(new RedisStandaloneConfiguration(Objects.requireNonNull(
environment.getProperty("redis.hostname")),Integer.parseInt(Objects.requireNonNull(
environment.getProperty("redis.port")))));
}
}
谁能帮我解决这个问题?
