解決：A child container failed during start

        新弄的電腦，項目怎麼都啓動不了，Tomcat一啓動就報錯：

        以「A child container failed during start」爲關鍵字找，基本上都說是Tomcat版本過高了，可是我以爲沒那麼簡單，由於我之前的電腦跑這個項目是Tomcat 8.0跑的，沒道理換個電腦就不行了，OK，那咱們換個思路，而後去找Caused by：後面跟的報錯，最後定位在這段日誌上：

        是maven下載的jar包有問題，所幸這位大佬和個人錯誤是如出一轍的，否則我還轉不過這個彎來，最後按照大佬的方法，把maven下載錯誤的jar刪掉從新下載，就OK了。

        方法1：可經過右擊項目名 ->  Run as -> Maven test ，這時控制檯會報哪一個jar包出錯。 （也能夠打開DOS命令窗口，切換至項目目錄，運行mvn test命令，和Eclipse的控制檯輸出信息一致）。

        方法2：若是方法1未出現任何錯誤信息，那麼就使用笨辦法。打開項目中的pom.xml文件，在本身的Maven本地倉庫去查找pom.xml文件中每個dependency節點所對應的jar包版本。一個一個對比，看看是否都正常下載。

        最後總結一下，最好備份一下本身的maven庫（能直接用的那種），就算有幾十個G也比找錯好多了。
