问题分析

产生错误的原因应该是jedis从连接池获取连接时，拿到的连接是一个无效的（可能是一个已经过期的连接），这时候拿到连接并没有对连接做有效性验证，而是直接使用它，导致了上述问题。

解决方案

开启了redis连接池的两个配置参数testWhileIdle、testOnBorrow为True，分别表示 在空闲时检查有效性、在获取连接的时候检查有效性 检查到无效连接时，会清理掉无效的连接，并重新获取新的连接。

下面给出以Spring boot项目为例的redis配置类：
properties配置文件

### redis
spring.redis.database=0
spring.redis.host=redis.zhuma.com
spring.redis.password=pro_woshimima
spring.redis.port=6479
spring.redis.timeout=5000
spring.redis.pool.max_idle=500
spring.redis.pool.min_idle=200
spring.redis.pool.max_active=2000
spring.redis.pool.max_wait=5000
spring.redis.pool.test-on-create=false
spring.redis.pool.test-on-borrow=true
spring.redis.pool.test-on-return=false
spring.redis.pool.test-while-idle=true

接收上述配置的Redis属性对象：

package com.zhuma.demo.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;

@Configuration
@ConfigurationProperties(prefix="spring.redis")

    private String host;

    private String password;

    private Integer timeout;

    private Integer port;

    @Autowired
    private Pool pool;

    @Configuration
    @ConfigurationProperties(prefix="spring.redis.pool")
    class Pool {

        private Integer maxIdle;

        private Integer minIdle;

        private Integer maxActive;

        private Integer maxWait;

        private Boolean testOnCreate;

        private Boolean testOnBorrow;//在获取连接的时候检查有效性

        private Boolean testOnReturn;//当调用return Object方法时，是否进行有效性检查  

        private Boolean testWhileIdle;//在空闲时检查有效性

        public Integer getMaxIdle() {
            return maxIdle;
        }

        public void setMaxIdle(Integer maxIdle) {
            this.maxIdle = maxIdle;
        }

        }

        public Integer getMaxActive() {

        }

        public void setMaxActive(Integer maxActive) {
            this.maxActive = maxActive;
        }

        public Integer getMaxWait() {
            return maxWait;
        }

        public void setMaxWait(Integer maxWait) {
            this.maxWait = maxWait;
        }

        public Boolean getTestOnCreate() {
            return testOnCreate;
        }

        public void setTestOnCreate(Boolean testOnCreate) {
            this.testOnCreate= testOnCreate;
        }

        public Boolean getTestOnBorrow() {
            return testOnBorrow;
        }

        public void setTestOnBorrow(Boolean testOnBorrow) {
            this.testOnBorrow= testOnBorrow;
        }

        public Boolean getTestOnReturn() {
            return testOnReturn;
        }

        public void setTestOnReturn(Boolean testOnReturn) {
            this.testOnReturn= testOnReturn;
        }

        public Boolean getTestWhileIdle() {
            return testWhileIdle;
        }

        public void setTestWhileIdle(Boolean testWhileIdle) {
            this.testWhileIdle = testWhileIdle;
        }

    }

    public String getHost() {
        return host;
    }

    public void setHost(String host) {
        this.host = host;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public Integer getTimeout() {
        return timeout;
    }

    public void setTimeout(Integer timeout) {
        this.timeout = timeout;
    }

    public Integer getPort() {
        return port;
    }

    public void setPort(Integer port) {
        this.port = port;
    }

    public Pool getPool() {
        return pool;
    }

    public void setPool(Pool pool) {
        this.pool = pool;
    }

}
