java沒錯navicat沒運作結果_運作eclipse.exe的程式時時沒有啟動Navicat.exe

運作程式時報錯：(Navicat.exe啟動借鑒手機百度-百度經驗@RSY_SXY《mysql如何啟動》)

HTTP Status 500 - Request processing failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is java.sql.SQLException: Cannot create PoolableConnectionFactory (Communications link failure

出現這種錯誤後，檢查navicat.exe

1、快捷鍵win+R，再輸入services.msc,點選确定

2、找到MYSQL，單擊右鍵，點選啟動

3，啟動後頁面

啟動後Navicat.exe
