我是靠谱客的博主 真实夕阳，最近开发中收集的这篇文章主要介绍Failed to invoke the method getXXX in the service Tried 3 times of the providers [xxxx dubbo填坑异常信息常规排错非常规解决，觉得挺不错的，现在分享给大家，希望可以做个参考。
概述
首先大的背景是这样的，公司的测试服务器是过年前才调好的。经过一番测试没有任何问题。用的框架是dubbo+zookeeper。过完春节回来，改了一个需求，用jenkins发版后。测试发现，dubbo总是提示消费端无法调用服务端的服务。异常信息如下：

... 67 more如上述代码所示：dubbo的消费者总是无法调用服务端的服务，并尝试了3次自动终止尝试。
常规排错
常规的解决办法如下：
主要就是检查配置文件，并查看服务是否成功注册
1.将服务的连接时间修改的久一点
<dubbo:service interface="" ref="" timeout="1200000"/>2.检查客户端接口和服务端接口的实现类是否一一对应
3.传输的参数过大，导致服务端返回给客户端的时候出现问题
经检查不是
4.返回的数据，没有进行序列化，导致结果返回不了给客户端
经检查是序列化的
5.进入zookeeper的控制台，通过ls命令查看服务是否注册成功
经检查服务是注册成功的
我把能用的常规方法用了一遍，依旧没有奏效
非常规解决
从根源去解决。
首先消费端只是提示调用服务超时。于是我去找服务端，服务端也没有报错。有关查询的操作也都是没有问题的。但是插入却不行。于是我定位到是数据库的问题。
找到测试数据库服务器df -h 我的天。数据库服务器磁盘使用量为100%。好了，问题就出在了这里。是数据库服务器没有了容量，难怪只有查询没问题，插入却不行。由于数据库的插入不行，所以导致service层服务拿不到返回值，以至于dubbo消费端提示服务端连接超时。
从服务器删除多余的log文件，释放磁盘空间后。问题解决。
这个问题解决了三天，一直在想是dubbo，zookeeper的问题。我把dubbo和zookeeper全部重新安装配置后，都没有解决。真的是把所有常规的方法都用了。绞尽脑汁也没想到会是这里出了问题。
所以以后解决问题还是不要只看问题的表面，要往问题的本质去考虑。
最后
以上就是真实夕阳为你收集整理的Failed to invoke the method getXXX in the service Tried 3 times of the providers [xxxx dubbo填坑异常信息常规排错非常规解决的全部内容，希望文章能够帮你解决Failed to invoke the method getXXX in the service Tried 3 times of the providers [xxxx dubbo填坑异常信息常规排错非常规解决所遇到的程序开发问题。
