這個問題之前出現過一次，和同事討論了2天，解決了。后來合 了一下master的分支，問題又出現了，但是忘記了解決方法。現在記錄一下免得時間長了又忘記了。
問題描述：

解決辦法先放在前面：
快捷鍵搜索com.taobao.tair.impl.mc.ShieldTairManager，仔細看，出現在兩個包里，按照自己的業務，在所有子模塊中根據maven help插件搜索，排除掉其中一個。
解決路程：
看到報錯一大堆，前面的基本都不用管，看最后報錯比較簡短的那一句。
com.taobao.tair.impl.mc.ShieldTairManager was loaded by com.taobao.pandora.boot.loader.ReLaunchURLClassLoader@6da9dc6, it should be loaded by Pandora Container. Can not load this fake sdk class. please refer to xxxx（這里是文檔地址，公司保密協議不好透露） for the solution
意思是說ShieldTairManager 這個類是Pandora Container容器加載的，請參考某某文檔解決，
復制下來文檔鏈接在瀏覽器打開，發現沒有權限，阿里的權限控制是做的比較嚴格的，到處都限制，好吧，那就不看文檔了。
按照需要Pandora Container容器加載的思路，腦海里出現各種假設，難道這個類被別的人修改過了？難道本地啟動不起來了嗎？難道我本地啟動的不是Pandora Container容器嗎？
思路錯了就會把你帶到無盡的深淵當中。
無意當中拷貝了com.taobao.tair.impl.mc.ShieldTairManager，快捷鍵在項目中搜索，發現這個類出現在兩個jar包中，
按照之前本地debug段點調試，發現一個奇怪的現象，
什么？構造器中構造一個對象時你直接給我拋出一個異常？？拋出的異常和項目啟動時候拋出的異常是一樣的，com.taobao.tair.impl.mc.ShieldTairManager was loaded by..........
看看ShieldTairManager出現在哪個jar包中，發現出現在一個A包中和一個B包中，B包是自己的外部依賴C引進來的，是需要的，那就把A包從項目中排除吧，
好吧，搜索各個子模塊，去掉A包，項目本地啟動，完美解決。
小經驗總結：
1.看異常看最后一個報錯，最后一個一般才是錯誤的主要原因。注意是一般。
2.思路錯了會帶你到無盡的深淵，一條路走不通試試另一條路。
3.一個類出現在兩個jar包中，會出現奇怪的問題，必須排除掉其中一個或者改變依賴順序。
4.要堅韌，要有耐心。
