Eclipse 啟動Tomcat失敗
阿新 • • 發佈：2019-01-09
背景：專案從windows移植到Mac下，Windows執行正常，Mac就是死活不正常，嘗試過N中方法，已崩潰。
說明：tomcat沒問題，jar包都不缺，環境也沒問題。
錯誤日誌如下：

從第一行錯誤日誌到最後一行，檢視過N多篇部落格，沒啥用。
本專案錯誤為：缺失Spring-web-xxx.jar;專案執行的jar包沒新增到Deployment Assembly裡面。
具體新增步驟為：（真是想不到會出現這種問題）
1. 右鍵單擊工程專案 ->點選 properties
2. 選擇 Deployment Assembly
3. 點選 Add -> Java Build Path Entries -> Next
4. 選擇 Maven Dependencies -> Finish -> Apply -> OK
5.重啟服務。
新增步驟也可檢視如下部落格，帶圖，此處懶得截圖了：
