Question

我正在尝试通过Jedis客户端连接到Redis服务器，但是我在连接时遇到了异常和堆栈跟踪-

org.springframework.data.redis.RedisConnectionFailureException：无法获取Jedis连接。嵌套的异常是redis.clients.jedis.exceptions.JedisConnectionException：无法从池中获取资源在org.springframework.data.redis.connection.jedis.JedisConnectionFactory.fetchJedisConnector（JedisConnectionFactory.java:204）在org.springframework.data.redis.connection.jedis.JedisConnectionFactory.getConnection（JedisConnectionFactory.java:348）在org.springframework.data.redis.core.RedisConnectionUtils.doGetConnection（RedisConnectionUtils.java:129）在org.springframework.data.redis.core.RedisConnectionUtils.getConnection（RedisConnectionUtils.java:92）在org.springframework.data.redis.core.RedisConnectionUtils.getConnection（RedisConnectionUtils.java:79）在org.springframework.data.redis.core.RedisTemplate.execute（RedisTemplate.java:194）在org.springframework.data.redis.core.RedisTemplate.execute（RedisTemplate.java:169）在org.springframework.data.redis.core.AbstractOperations.execute（AbstractOperations.java:91）在org.springframework.data.redis.core.DefaultHashOperations.get（DefaultHashOperations.java:49）在jdk.internal.reflect.GeneratedMethodAccessor122.invoke（未知来源）在java.base / jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke（DelegatingMethodAccessorImpl.java:43）在java.base / java.lang.reflect.Method.invoke（Method.java:564）在org.springframework.scheduling.support.ScheduledMethodRunnable.run（ScheduledMethodRunnable.java:65）在org.springframework.scheduling.support.DelegatingErrorHandlingRunnable.run（DelegatingErrorHandlingRunnable.java:54）在org.springframework.scheduling.concurrent.ReschedulingRunnable.run（ReschedulingRunnable.java:81）在java.base / java.util.concurrent.Executors $ RunnableAdapter.call（Executors.java:514）在java.base / java.util.concurrent.FutureTask.run（FutureTask.java:264）在java.base / java.util.concurrent.ScheduledThreadPoolExecutor $ ScheduledFutureTask.run（ScheduledThreadPoolExecutor.java:304）在java.base / java.util.concurrent.ThreadPoolExecutor.runWorker（ThreadPoolExecutor.java:1135）在java.base / java.util.concurrent.ThreadPoolExecutor $ Worker.run（ThreadPoolExecutor.java:635）在java.base / java.lang.Thread.run（Thread.java:844）引起原因：redis.clients.jedis.exceptions.JedisConnectionException：无法从池中获取资源在redis.clients.util.Pool.getResource（Pool.java:53）在redis.clients.jedis.JedisPool.getResource（JedisPool.java:226）在redis.clients.jedis.JedisPool.getResource（JedisPool.java:16）在org.springframework.data.redis.connection.jedis.JedisConnectionFactory.fetchJedisConnector（JedisConnectionFactory.java:194） ...另外24个引起原因：redis.clients.jedis.exceptions.JedisConnectionException：java.net.ConnectException：连接被拒绝（连接被拒绝）在redis.clients.jedis.Connection.connect（Connection.java:207）在redis.clients.jedis.BinaryClient.connect（BinaryClient.java:93）在redis.clients.jedis.BinaryJedis.connect（BinaryJedis.java:1767）在redis.clients.jedis.JedisFactory.makeObject（JedisFactory.java:106）在org.apache.commons.pool2.impl.GenericObjectPool.create（GenericObjectPool.java:888）在org.apache.commons.pool2.impl.GenericObjectPool.borrowObject（GenericObjectPool.java:432）在org.apache.commons.pool2.impl.GenericObjectPool.borrowObject（GenericObjectPool.java:361）在redis.clients.util.Pool.getResource（Pool.java:49） ...另外27个引起原因：java.net.ConnectException：连接被拒绝（连接被拒绝）在java.base / java.net.PlainSocketImpl.socketConnect（本机方法）在java.base / java.net.AbstractPlainSocketImpl.doConnect（AbstractPlainSocketImpl.java:400）在java.base / java.net.AbstractPlainSocketImpl.connectToAddress（AbstractPlainSocketImpl.java:243）在java.base / java.net.AbstractPlainSocketImpl.connect（AbstractPlainSocketImpl.java:225）在java.base / java.net.SocksSocketImpl.connect（SocksSocketImpl.java:402）在java.base / java.net.Socket.connect（Socket.java:591）在redis.clients.jedis.Connection.connect（Connection.java:184）

这是Jedis Pool的配置-

@Bean
    public JedisPoolConfig jedisPoolConfig() {
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        jedisPoolConfig.setMaxWaitMillis(5000);
        jedisPoolConfig.setMaxIdle(8);
        jedisPoolConfig.setMinIdle(1);
        jedisPoolConfig.setMaxTotal(10);
        return jedisPoolConfig;
    }

@Bean
public JedisConnectionFactory jedisConnectionFactory() {
        JedisConnectionFactory factory = new JedisConnectionFactory();
        factory.setPoolConfig(jedisPoolConfig());
        factory.setShardInfo(shardInfo());
        factory.setHostName(serviceConfiguration.REDIS_HOST_NAME);
        factory.setPort(serviceConfiguration.REDIS_PORT);
        factory.setUsePool(true);
        return factory;
}

请提出建议，为解决此问题应该更改或尝试什么？

确保您还正确配置了连接工厂Bean

 @Bean
  public JedisConnectionFactory redisConnectionFactory() {

    RedisStandaloneConfiguration config = new RedisStandaloneConfiguration("server", 6379);
    return new JedisConnectionFactory(config);
  }

ConnectException：连接被拒绝（连接被拒绝）-通过Jedis连接到Redis时
