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。

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

我好帅
