NoClassDefFoundError 是一個(gè)異常涯保，表示 Java 虛擬機(jī)無(wú)法找到指定的類及刻。這個(gè)異常通常發(fā)生在以下情況下：
- 類庫(kù)版本問題：指定的類可能在特定的庫(kù)版本中不存在讥珍。請(qǐng)檢查類庫(kù)的版本是否與代碼中使用的版本兼容。
- 依賴問題：應(yīng)用程序可能缺少指定的類的依賴狸剃。請(qǐng)確保項(xiàng)目中包含了相應(yīng)的依賴。
于是查看了版本依賴問題

導(dǎo)致的原因梧兼，應(yīng)該是類庫(kù)版本的問題女仰，右側(cè)依賴選項(xiàng)也提示2.6.13.
隨后，在pom.xml文件中轧抗，將2.0.1.RELEASE 修改為 2.6.13
再次運(yùn)行恩敌，成功啟動(dòng)~
