Redis经常会报出RedisConnectionFailureException: java.net.SocketException: Broken pipe_redistemplate broken pipe

【背景】： 在测试和生产环境上，偶尔会出现如下的redis异常。
在APP层面的现象就是界面提示：”网络连接异常”，但下次点击APP的时候，又可以正常使用了。

【问题原因】

Redis底层也创建了连接池，获取到了失效的连接池，并且Redis客户端尝试通过此连接池跟服务端进行通信， 导致抛出上面的异常。

【解决办法】

Redis配置的连接池使用jar包commons-pool-2.4.2.jar方式。

private boolean testOnCreate = false;
private boolean testOnBorrow = false;
private boolean testOnReturn = false;
private boolean testWhileIdle = false;

其中有如上述四个属性参数。只要配置 testOnBorrow = true 和 testWhileIdle = true 就可以。 其中 testOnBorrow = true 是获取链接的时候对链接的有效性进行检查，会影响效率，在高并发的前提下。所以一般只是配置 testWhileIdle = true ， 这个是在闲暇的时候进行检查，去除无效的链接。

【思考】

如果采用spring boot自动集成的方式，如何去设置testOnBorrow 这个参数呢？ 因为默认情况下，testOnBorrow 是false方式。难不成为了修改这个参数，重新去自定义一个Redis的Bean？？
