步驟：
1、點選右側的datesource圖示，要是沒有該圖示，請去自行百度
2、點選 + 号
3、選擇 datasource
4、選擇 mysql
1、填寫一個連接配接名，随便填什麼都行
2、不用選擇，預設就行
3、填寫資料庫連接配接的 IP位址，比如本地資料庫可以填寫：localhost或者127.0.0.1
4、填寫資料庫開放的端口号，一般沒設定的話預設都是3306
5、填寫你需要連接配接的資料庫名
6、填寫資料庫的使用者名
7、填寫資料庫密碼
8、這裡會有一個驅動需要點選下載下傳，圖中是已經下載下傳好了
9、填寫自己的資料庫連接配接url，然後可以點選9所在按鈕進行測試連接配接，本地連接配接失敗檢查是否開啟了mysql服務
連接配接好了如上圖所示，可以看到自己的資料庫和表，選擇一個表右鍵，選擇Generate POJOs.groovy，然後在彈出視窗選擇需要生成的檔案夾所在即可。
首先轉到腳本目錄
然後 建立一個檔案 Generate model.groovy
粘貼代碼：

然後選擇剛才建立的檔案，選擇目錄實體類就會生成剛才所在的目錄
