估計(jì)是和dubbo有點(diǎn)沖突
dubbo報(bào)錯(cuò)總結(jié)
作為一個(gè)dubbo使用新手，有必要總結(jié)一些常見(jiàn)的dubbo問(wèn)題，提升解決問(wèn)題的套路。
1.dubbo consumer 調(diào)用provider報(bào)錯(cuò)（1）- No provider available
問(wèn)題：
No provider available from registry xxx from service xxx on consumer xxx may be providers disabled or not registrered。
如下圖所示：
原因：
根據(jù)源碼的截圖所示（下圖），就兩個(gè)原因：
1）No service provider
2）Service providers are disabled
解決辦法：
1).provider部署分支不正確，部署正確的分支。
2).consumer部署分支的zookeeper地址不正確。
2.dubbo consumer調(diào)用provider報(bào)錯(cuò)（2）
問(wèn)題：
com.alibaba.dubbo.rpc.RpcException: Rpc cluster invoker for interface xxx on consumer 10.2.4.63 use dubbo version 2.6.0.2 is now destroyed! Can not invoke any more.
原因：
調(diào)用鏈路：invoke()–>checkWhetherDestroyed()
consumer端調(diào)用的時(shí)候，發(fā)現(xiàn)出現(xiàn)實(shí)例已經(jīng)destory，就拋出此異常
懷疑是由于內(nèi)存不足，dubbo進(jìn)程觸發(fā)了spring的destroy()方法，同時(shí)就執(zhí)行到了AbstractClusterInvoker.destroy()，但是此時(shí)進(jìn)程并沒(méi)有掛掉，所以就出現(xiàn)了可以調(diào)用，但是調(diào)用失敗的情況。
解決方法：
1）查看provider服務(wù)器是否內(nèi)存不夠，kill掉不相干的進(jìn)程。
2）重啟provider服務(wù)。
3.dubbo consumer 調(diào)用provider報(bào)錯(cuò)（3）- NoSuchMethodException
問(wèn)題：
Caused by: com.alibaba.dubbo.common.bytecode.NoSuchMethodException: Not found method “getSocialResourceByRegionId” in class com.missfresh.product.center.service.impl.SocialResourceServiceImpl.
原因：
dubbo服務(wù)部署的分支里沒(méi)有相關(guān)接口的實(shí)現(xiàn)。
解決方法：
部署對(duì)應(yīng)的分支。或者是直接部署master。
4.dubbo consumer 調(diào)用provider報(bào)錯(cuò)（4）- Thread pool is EXHAUSTED!
問(wèn)題：
com.alibaba.dubbo.rpc.RpcException: Failed to invoke the method queryProductSalsPromotionTagList in the service com.missfresh.product.center.service.IProductCategorysService. Tried 1 times of the providers
原因：
如上圖所示，provider服務(wù)支持的最大線程數(shù)為300。
解決方法：
檢查程序中并發(fā)采用的線程池初始化值，是否合理。最大線程個(gè)數(shù)不能大于300.
總結(jié)
以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
