... 6 more找了好久找不到原因，以为是jedis版本、redis版本、或者pool版本不匹配发现都不是。
最后在这里找到了答案https://www.cnblogs.com/machanghai/p/5497084.html
具体解决方案
将redis.conf中的bind 127.0.0.1 修改为 0.0.0.0
为什么不是注释掉(前面加#号)，注释掉会出现其他错误，具体我也不清楚。
修改后效果如下
...
# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT THE FOLLOWING LINE.
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
bind 0.0.0.0
# Protected mode is a layer of security protection, in order to avoid that
# Redis instances left open on the internet are accessed and exploited.
#
# When protected mode is on and if:
#
# 1) The server is not binding explicitly to a set of addresses using the
# "bind" directive.
# 2) No password is configured.
...java程序
package com.zhujunwei.jedis;
import redis.clients.jedis.Jedis;
public class TestJedis {
@SuppressWarnings("resource")
public static void main(String[] args) {
// Jedis jedis = new Jedis("192.168.40.147");
Jedis jedis = new Jedis("192.168.40.147",6379);
String name = jedis.get("name");
System.out.println(name);
}
}
运行结果
